Gas wall-mounted boilers Navien - operation and troubleshooting

Setting the gas pressure of Navien boilers

To set the gas pressure of Navien boilers (Ace, Deluxe, Prime, Atmo), you will need a differential digital pressure gauge with a mm H2O scale.
A table with gas pressure values ​​for various Navien boiler models is given at the end

1.With the boiler turned off, attach a pressure gauge to the gas pressure control fitting on the burner

2. Turn on the boiler

3. Set DIP switch 3 on the control board to the “ON” position, which will correspond to the minimum load.

4. Set the minimum gas pressure according to the table using the screw for setting the minimum pressure (Increase - counterclockwise, decrease - clockwise)

5. Set DIP switch 3 on the control board to the “OFF” position (Main state)

6.Set DIP switch 2 on the control board to the “ON” position, which corresponds to the maximum load

7. Set the maximum gas pressure in accordance with the table using the adjusting screw (Increase - counterclockwise, decrease - clockwise)

9. Disconnect the differential pressure gauge hose from the gas valve fitting

10. Set the DIP switch to the “OFF” position (Main state)

11. Turn on the boiler

12 . Check the tightness of the gas valve (Fitting). If abnormal noises appear, you need to check the boiler for gas leaks.

Hello! Tell me, is it possible to programmatically reduce the boiler power and if so, how to do it?

Will they lie to you if you succeed, because this is determined by the very model of this particular boiler. (IMHO)

The boiler power can be reduced to 13 kW. Without loss of power for hot water supply. To do this, set DIP switches No. 8-9-10 on the boiler control unit in a certain position. Settings for different powers are given in the user manual. After installation, it is necessary to check and adjust, if necessary, the gas pressure on the burner MIN and MAX according to the installed power.

Is it true that there is no loss of power on the hot water supply? The maximum pressure on the burner at 24 is 88, and 16 is already 43. Do you want to say that with such a difference the DHW will heat the same?

In the DHW preparation mode, the wall units switch to maximum power themselves.

How can it switch if it is “pinched”, i.e. ordered no more? If it has provision for adjusting the maximum heating power, usually through software, with knobs and buttons, then yes, but if the supply is limited by a valve, then it’s a big deal.

Setting dips - sets a certain range of maximum gas pressure on the burner. Fine tuning is done by turning the resistor. It is installed next to the DIP. When operating on DHW, with boilers set to 13-16-20, the maximum pressure on the burner corresponds to 20 kW. The minimum is 11-16 mm. 10K-13K-16K-20K-24K are the same boiler (Korean version). Like 35K-40K. For boilers of the “European” type (Coaxial) - the 24K has a larger secondary heat exchanger. “It is possible to tighten the maximum heating power without loss of hot water on any modern boilers.

How I set up the Navien boiler, hysteresis on the burner

The boiler heats up, life goes on, but something told me that everything is not so rosy, first of all, a mistake was found among many buyers of gas boilers, they all buy with a reserve of power “just in case,” well, I, like everyone else, I took it with a reserve, with a reserve for hot water supply and frosts, i.e. It turned out that in warm weather outside, the Navien boiler continues to cycle , which is very unfortunate for it, and can lead to breakdown, first of all, there may be a breakdown of the ignition system , since it constantly lights the boiler, and most often wears out, this is not for me I want to.
As an inquisitive researcher, with a stopwatch in my hands, I studied the cycles of the boiler in different modes of its operation, in warm weather, in cold weather, and decided to test the capabilities of the boiler at work depending on the temperature in the room, for this I selected the room mode in the boiler settings.

At first everything was happy, the boiler obediently stood up, waiting for the set temperature to drop, but the joy was short-lived, cold was already creeping across the floor (the heat from the radiators, which cut off the cold air from my many windows, disappeared, and the house became not very comfortable, in the upper part the room where the remote control for the boiler, in which the temperature sensor is located, hung. It was in a warmer zone, we immediately understood that this was not suitable for us, at first there were thoughts of hanging the remote control down, closer to the floor, but, firstly, this is inconvenient for control, secondly, it can be ruined by domestic cats, thirdly, the boiler may not turn off at all, trying to catch up with the temperature below, when it is already hot in the middle part of the room in height.

The room temperature test did not pass and was not suitable for me, at the same time I remembered the person who connected the gas, who advised that the boiler should not be turned on in this mode.

Time passed, but the cycles did not give me peace, and one day it occurred to me, while regularly observing the boiler, that the hysteresis (delta) in the turn-on-switch-off segment of the gas boiler was probably too small, and I would like the boiler to drive the coolant longer to a higher level. low CO temperature, but it was unclear how to do this, I certainly know how to program, but programming languages ​​for this boiler are inappropriate, and I don’t have equipment to connect to the “brains” of the boiler, and one day, purely by chance, I came across one well-known forum for a person who knows how to do this, and with the help of only one remote control, by entering the engineering menu of the Navien boiler!

This is literally what needs to be done. to change the delta between boiler start-stop.

1. With the Navien boiler remote control turned off, press the + and - buttons for 5 seconds

2. The number 8 or 9 or 10 will appear on the remote control display (for me)

3. Again, use the + or - buttons to change the value (this is delta) in the range from 2 to 20 (I set it to 12)

4. We wait 5 seconds, after which the boiler remote control goes out

5. Turn off the boiler by removing the plug from the socket for at least 10 seconds

6. Temperature difference value saved

Having done all this, I immediately realized the difference, the intervals between starts and stops of the boiler increased, although it raised the delta by only 2 degrees!, a useful thing, the engineering menu of the Navien boiler!

Features of the Navien gas boiler

Navien produces devices of various capacities designed to provide heating for gas-fired homes. However, the technical features of the models allow them to be converted to an autonomous gas supply, that is, connected to cylinders.

A wide range of models allows you to choose a model to suit any needs and capabilities.

• wall and floor;
• single-circuit and with hot water supply;
• with atmospheric and closed combustion chamber;
• with different heating outlet sizes (three options: 20, 25, 32);
• with different chimney diameters;
• and of course, the models differ in power and size.

The manufacturer did not neglect the design.

The devices have an elegant appearance and fit well into a kitchen or any other interior.

Security systems supplied with Navien boilers:

• Modulated turbocharging.
• Protection against coolant freezing.
• A special chip (SMPS) protects against 30% power surges.
• A control panel with a temperature sensor that allows you to maintain t constant and adjust the operation of the boiler to special circumstances.

Modulated turbocharging. The system is based on the interaction of a fan supplying combustion air and a pressure sensor (APS).

The fan rotation intensity changes in proportion to how much gas is supplied at the moment. This allows you to use resources economically and increase efficiency without wasting fuel.

Owners take the choice of equipment such as a gas boiler seriously. Read information about the Baxi gas boiler, the manufacturer, as well as the unit models on our website.

Read about the purpose of an air valve for heating here. Operating principle and design features.

Setting up a Navien gas boiler with your own hands

Among the numerous boilers, the Navien brand is one of the most popular in the domestic market. It is reliable and affordable. They produce equipment of this brand of different capacities and configurations. The boilers look stylish and fit into any interior. In addition, they are equipped with protection against voltage surges, coolant freezing and other equally useful functions.

Korean Navien heating units have proven themselves to be reliable units. That is why buyers increasingly give preference to them and are interested in how to configure them correctly. Can I do this myself? What does this require?

Features of setting up the Navien boiler

All settings are made using a remote control equipped with a room temperature sensor. It is included with the device. All commands are Russified and simple, which makes controlling the boiler much easier. You can activate the device with a remote button, which can also pause the operation of the unit.

Air temperature

Setting it up is simple: hold down the radiator button until the image of a “house with a thermometer” appears. While it is flickering, the desired indicators are entered. You can set the desired parameters using the minus/plus buttons. Temperature range - from 10 to 40 degrees. The settings are saved automatically.

Temperature adjustment

You can adjust it by pressing the button with a picture of a radiator. To set the desired temperature range, use the plus/minus buttons with the radiator icon flickering. The settings are saved automatically and displayed on the screen. Temperature range 40-80 degrees.

"Outside Home"

Performs the function of heating water without heating. You can enable this mode by holding the arrow and the “water tap” button. After this icon appears on the screen, the mode is considered running. The temperature in the room will also be displayed on the screen.

When should you enable the “away from home” function?

It is optimal for the summer period, when heating is not required, but there is a need for an uninterrupted supply of hot water.

Setting the hot water temperature

You can set the necessary parameters in the following way: hold down the “water tap”, set the temperature using plus/minus. Temperature range - 30-60 degrees. The settings are saved automatically.

For reference! The “Hot water priority” mode is regulated differently. To do this, hold down the “water tap” until the symbol appears and then enter the necessary data. This mode is designed to provide the room with water at a given temperature in the required volume.

Timer mode

Allows you to set the desired boiler mode. It can function by turning itself off after a set period of time automatically. To set the timer, you need to hold down the image of the radiator until the “clock” icon appears. After this, the desired work interval is set. After adjustment, the room temperature will be displayed on the screen.

How to change the boiler startup/shutdown frequency?

When faced with the problem of frequent shutdown/startup of the system, you can adjust the frequency of stopping and starting within a few minutes. To do this, you need to simultaneously hold down the plus/minus buttons and select the appropriate value for starting and shutting down the system. After this procedure, the boiler should be disconnected from the network for a maximum of 10 seconds and started again so that it operates in the new mode.

Design and main elements of the boiler

It is important to know your boiler in order to carry out basic maintenance. Although the model may vary from model to model, the main elements can be found in the case:

• combustion chamber;
• heat exchanger;
• expansion tank;
• gas burner;
• circulation pump;
• Control block.

Particular attention should be paid to the design of the lower part of the case, since this is where the inputs and outputs of the circuits are connected, and other important parts are located.

Gas wall-mounted boiler NAVIEN

When a consumer is faced with the question of choosing the right gas water heater for heating, he has to keep in mind a considerable number of parameters that ensure its effective and economical operation. In this regard, it is necessary to divide domestic and foreign units. Unfortunately, not all “foreigners” are able to withstand the difficult Russian operating conditions - poor quality of the coolant, changes in gas and water pressure, periodic shutdowns of electrical energy. True, many foreign analogues are currently already adapted to the conditions of our country. For example, the famous South Korean line of “Navien Ace” models with a manual where it is discussed that these boilers are used in Russia.

The Navien Ace brand is a wall-mounted version of a double-circuit unit. A similar model refers to Navien equipment with an open firebox and real exhaust of combustion products. What is included in the boiler design?

Boiler equipment

The design of the unit includes:

• Two pipe coils are made of stainless steel, this ensures their long and good operation.
• Remote monitor of the control unit, which is completely Russified. For the Russian consumer this is a very important condition.
• Built-in circulation pump.
• Expansion tank.
• Valve for protection.
• Mayevsky crane operating in automatic mode.
• Bypass valve, which can also be adjusted in automatic mode.
• Traction meter.
• AC stabilizer.
• Remote control, which is convenient in terms of maintenance.

The South Korean boiler navien ace is fully equipped with Japanese automation. In this case, the manufacturer provides a warranty period of 2 years. This is a fairly small device with impressive technical properties. The operating instructions for Navien boilers make it easy to understand all the details of setting up the device, modes and temperature ranges.

Classification

Gas boilers “Navien Ace” are divided into two categories:

The first device is a simple convection boiler with an open firebox, where the weather removal of combustion products is used. The second is more improved and has a turbocharged burner. This makes it possible to supply gas very efficiently and burn it during unstable supply, which is associated with pressure surges. Also, another option is equipped with a specialized SMPS control system, which is based on highly sensitive chips. They are responsible for monitoring and regulating gas combustion processes. In all other respects, both options are no different from each other.

Two models can be classified as multifunctional equipment. Adapted to difficult operational requirements, they are one of the very economical radiator designs that are currently on the Russian market. A significant component of the design is the remote control. This is quite convenient when you can set modes and indicators from a distance, quickly making adjustments.

However, what is unusual is that Navien gas boilers will usually operate not only in automatic mode, but also in manual mode. This is even more comfortable when the temperature outside the window changes sharply. Manual installation makes it possible to more accurately set parameters and indicators, which eliminates the smallest errors during operation of heating equipment.

Navien ace gas boilers can be called multifunctional units. They operate on natural gas or liquefied bottled gas. To switch from one type of gas to another, only the burner should be replaced. No other changes will be required.

What should you pay attention to during installation?

Steel gas boiler Navien Ace

Since instructions are included with the equipment, there are no difficulties with installing and connecting the device. Doing it on your own is not a problem. Even an amateur can understand the instructions. Moreover, it is written in Russian.

The only thing that professionals ask you to pay attention to is the method of removing carbon monoxide. They can be removed through a simple weather-resistant chimney connected to the house's smoke exhaust system or installed as a separate structure. However, if you are not satisfied with any option, you can create a coaxial type chimney. Its installation is many times easier. But keep in mind that coaxial structures are used exclusively in cases where the heated area of ​​the house will not exceed 110 m2. They can be installed with boilers whose power will not exceed 11 kW.

Operating modes

Like many heating appliances, Navien boilers have winter and summer operating modes. On the display, the mode change button is indicated by the “Snowflake” and “Sun” icons.

By pressing this button again, you can change the options:

• Winter mode activates heating and hot water supply.
• Summer is only hot water supply for household needs.

You can adjust the coolant temperature on the remote control when the heating radiator icon lights up on the display.

In some models, to do this you need to press the “Heating Mode” button, in others you need to turn the knob with this icon.

A flashing radiator icon means that the numbers you see show the set temperature of the coolant.

If the “radiator” just lights up, the actual temperature in the heating is displayed.

Having selected “radiator”, you need to press the “+” or “-” keys to increase or decrease the temperature. A few seconds after the desired temperature is set, the radiator icon stops blinking, and the display will show what temperature the coolant is now, and the device will begin to gradually heat it (or cool it) to the selected one.

How to turn off the heating on a Navien Ace boiler: switch to summer mode

Thanks to their reliability and low price, Navien Ace boilers produced by the Korean company Navien have become the most popular brand in Russia. Due to their modern design, Navien Ace boilers are considered the most compact wall-mounted boilers on the market.

In addition, their modern appearance will easily fit into almost any interior.

Ease of operation will allow both elderly people and children to set a comfortable level of heat and hot water temperature for themselves. But with the onset of spring, people are increasingly asking one question: “How to turn off the heating on a Navien ace boiler?”

It is this question that we decided to answer in this article.

We have prepared detailed instructions for Navien Ace: how to turn off the heating and / or increase the heating of hot water.

First, let's look at the control panel and what is on it:

1. There is a display on the control panel; this is where the current operating mode of the boiler and the set temperature of the heating system and hot water are displayed.

2. The icon in the form of a radiator shown on the display means that the boiler is now operating according to the temperature of the water in the heating system (in the batteries).

3. The inscription Fact is the actual temperature of the water inside the radiators.

4. To set the water temperature in the heating system, you must press the key with the image of a radiator.

After pressing the key, using the + - keys, you can set the required temperature of the heating fluid.

After selecting the required temperature, you will see the radiator image blinking and the display will change to “set”.

Upon reaching the set temperature, the boiler will turn off and start again when the water in the heating system cools.

5. There is a timer on the control panel. To switch to this mode, you need to press the key with the image of a radiator three times.

By setting the time on the timer, you set the time the boiler is inoperative. After this time, the boiler will operate for 30 minutes and turn off again. This operating mode will allow you to choose how much time in a day the boiler will operate.

6. By pressing the key with the image of a radiator, you can select the heating mode according to the room temperature.

Thanks to the presence of a thermostat in the control panel, it is possible to operate the boiler according to the air temperature in the room. That is, the boiler will not pay attention to the temperature of the coolant in the pipes.

Its task will be to heat the air in the room to a temperature comfortable for the owner.

7. By clicking on the mixer image, you can select the hot water heating temperature.

8. But still, how to turn off the heating on a Navien Ice boiler? To do this, press the key

After this press, the boiler goes into the “Away” mode, or as it is also called, “Summer mode”. In this mode, the boiler completely stops working for heating and switches only to heating hot water.

The hot water temperature will be equal to the temperature you set in the previous paragraph.

The minimum temperature of the coolant can reach 40 C, and the maximum should not exceed 80 C.

9. Also, on the control panel, there is a button to turn off the boiler.

When pressed, the boiler will turn off.

Once turned on, it will light the burner (if necessary at that time), and continue to work, executing the commands of the last mode in which it was turned off. If the key icon lights up red, this means there is a problem with the boiler.

To resolve it, it is best to immediately contact your nearest Navien service center.

Well, we have figured out how the Navien Ace boiler control panel works. Now you know how to turn off the heating on a Navien ace boiler, as well as much more. Thanks to this knowledge, you will never again ask the question “Navien Ace how to turn off the heating,” and when hot days come, you will not sweat in a stuffy apartment or house. If you have any questions, feel free to ask us by phone. Or write in the chat on this page. Always happy to help!

Precautionary measures

The room where the boiler is located must be well ventilated.

Gas cylinders, if used, should be stored in a separate cool room.

Do not dry things on gas heating pipes.

The power supply parameters must meet the requirements for the specific model (For example, 220V, 50 Hz).

The unit must be plugged into a separate outlet (other devices cannot be plugged into it); extension cords and adapters are not allowed.

Do not touch the body of the device with wet hands or plug it into the mains.

A working device must be in a protective housing.

You cannot install or repair gas equipment yourself - this is the work of government services. Once a year, these services will conduct a preventive inspection of the boiler.

If bubbles appear, immediately turn off the gas valve, provide air flow and call emergency services.

Tips and recommendations for operating the Navien boiler

The main advice from experts regarding the safe operation of the boiler:

1. The room where the unit is located must have good ventilation.
2. The unit must have a separate independent connection to the electrical network.
3. The boiler must operate in a fully assembled and protective housing.
4. The user is prohibited from independently repairing the gas equipment of the boiler.
5. The boiler must undergo an annual inspection by representatives of Gorgaz.
6. The boiler owner must periodically check the joints of the boiler and the gas pipeline for leaks with a soap solution.

Additional Information. If leaks occur, immediately turn off the gas valve, ventilate the room and call the emergency gas service.

Navien gas boilers have been used by Russian consumers for a long time. They have rightly earned the trust of customers. The lightweight layout with the widest range of modern water heating functions allows you to choose these models from a large list of offers on the heating equipment market.

Korean-made Navien heating boilers are popular in our country. They are reliable and at the same time affordable in price. Due to the great demand for these devices, setting up a Navien gas boiler is a pressing issue among buyers.

Filling the boiler and heating system with water

Error code 02 indicates that there was an attempt to start the boiler, but there is no water in the system, or there is not enough water. What to do:

1. The appliance is unplugged and the gas supply is cut off.
2. At the bottom of the boiler, among many elements, you need to find a make-up valve. Turning it counterclockwise opens it, and turning it clockwise closes it.
3. When the tap is open, monitor the pressure gauge. You need to close the tap when it shows 1.3 - 2 bar.
4. Now the boiler is connected again, gas is supplied and the start is made.

Don't worry if error 02 appears again. This may be caused by the fact that after bleeding the air (which is automatically done at startup), the water level is again insufficient. The filling operation must be repeated.

How to increase the time between starting and shutting down a gas boiler?

If there is a problem with frequent switching on and off (“clocking”) of a gas boiler, you can change the difference between starting and stopping the unit. This is possible using the Navien engineering menu:

1. Turn off the remote control and press two buttons “+” and “-” at the same time.
2. A number from 2 to 20 appears on the display. Usually 8 or 10.
3. Use the “+” and “-” keys to increase the delta value between start and shutdown.
4. After 5 seconds, the remote control goes out.
5. The boiler is turned off and then turned on again.

Now the gas unit will operate in a new mode.

Draining water from the boiler and hot water supply system

If the boiler is not planned to be used for a long time (especially in winter), it is recommended to drain all water from the heating and hot water circuits. What to do:

1. The unit is de-energized and the gas valve is closed.
2. The valves of the heating system (2 pieces) and cold water are closed.
3. The tap that is usually used opens (above the sink, for example) and drains hot water from the system.
4. The tap in the DHW system is closed.
5. A plug is opened at the bottom of the housing and water from the heating is drained.

Navien gas boiler - instructions for safe use and care

Heating installations with Korean “roots”, Navien, are constantly used both in private houses outside the city and in residential areas.

What is the reason for this popularity, what design features does the equipment have and what difficulties may a buyer encounter when purchasing a Navien gas boiler.

Instructions for safe use (operation), selection of model and good care. We'll tell you about everything further.

Specifications of the Navien gas water heater

Navien produces devices of various capacities designed to provide heat supply to gasified houses. However, the technical characteristics of the models allow them to be converted to an independent gas supply, in other words, connected to cylinders.

A large range of models makes it possible to choose a model to suit any needs and capabilities.

There are boilers:

• wall and floor;
• single-circuit and with hot water supply;
• with atmospheric and closed firebox;
• with a variety of outlet sizes for heat supply (three options: 20, 25, 32);
• with a wide variety of chimney diameters;
• and of course, the models differ in power and size.

Gas Double-Circuit Boiler NAVIEN 24 Review and Feedback!

The manufacturer did not neglect the design.

The devices have a beautiful overall appearance and fit perfectly into a kitchen or any other interior.

Security systems equipped with Navien boilers:

• Modulated turbocharging.
• Protection against freezing of the coolant.
• A specialized chip (SMPS) protects against 30% voltage surges.
• A control panel with a thermal converter, which makes it possible to maintain t constant and adjust the operation of the boiler to special circumstances.

Modulated turbocharging. The system is based on the mutual action of a fan supplying combustion air and a pressure sensor (APS).

The fan rotation intensity changes in proportion to how much gas is flowing in now. This makes it possible to use resources practically and increase efficiency without additional fuel consumption.

Design and important elements of the boiler

You need to know your own boiler in order to perform very simple maintenance operations. Although the model differs from model, important elements can be found in the case:

• firebox;
• pipe coil;
• expansion tank;
• atmospheric burner;
• circulation pump;
• Control block.

Much attention should be paid to the design of the part that is located at the bottom of the case, since this is where the inputs and outputs of the circuits are connected, and other main parts are located.

Gas boiler Navien | How to use a gas boiler

Navien boiler diagram

Closer to the wall there are 4 connecting pipe sections:

1. Feed input.
2. Return inlet (with safety valve).
3. Hot water outlet.
4. Cool water.

Next is a small section of gas supply pipe.

A hot water filter is placed in front of the return inlet, and a drain plug is located even closer.

A make-up tap is placed in front of the DHW outlet, with which the system is filled with water.

The working principle of the anti-freeze system. When the temperature in the pipes drops below the -10° mark, the pump automatically turns on, which circulates the coolant and prevents it from freezing.

If the temperature drop continues and it reaches -6°, the burner is activated, which heats the water to +21°.

Operating modes

Like many heating devices, Navien boilers have winter and summer operating modes. On the screen, the mode change button is marked with the “Snowflake” and “Sun” icons.

By pressing this button again, you are allowed to change the options:

• Winter mode uses heat supply and hot water supply.
• Summer is only hot water for household needs.

You can set the temperature of the coolant on the remote control when the icon with a heating radiator lights up on the screen.

In some models, for this you need to press the “Heat supply mode” button, in others you need to turn the knob with this icon.

A flashing heater icon means that the numbers you see show the set temperature of the heating medium.

If the “heater” just lights up, the actual temperature in the heating supply is displayed.

Having selected a “heating device”, you need to press the “+” or “-” keys to make more or lower the temperature. A couple of seconds after the desired temperature is set, the heating device icon stops blinking, and information appears on the screen about what temperature the coolant is currently in, and the device will begin to gradually heat it up (or cool it) to the selected temperature.

You can set t in the heat supply within the range from 40 °C to 80 °C with a plus sign.

Temperature control of hot water supply

To make more or less hot water, you need to press the tap icon on the remote control.

By turning the knob or adjusting the temperature using the plus and minus buttons, you can set the required heating level. It is recommended to do this not while taking a shower, but in advance.

The adjustment step is 1 °C. The limits within which t varies: from +30 to 60 °C.

Navien boiler, instructions.

Precautionary measures

The room where the boiler is located must be well ventilated.

Gas cylinders, if used, must be stored in a separate, cool room.

You cannot dry things on gas heating pipes.

The parameters of the electrical network must meet the requirements for a specific model (For example, 220V, 50 Hz).

The device must be plugged into a separate outlet (other devices cannot be plugged into it); extension cords and adapters are not allowed.

Do not touch the body of the device with wet hands or plug it into the network.

The operating device must be in a protective housing.

You cannot install or repair gas-powered equipment on your own - this is the work of government services. Once a year, these services will conduct a boiler inspection.

Sometimes it is necessary to check all joints of the boiler and pipeline for leaks. Applying a thick, soap-based solution will indicate if there is a gas leak.

If bubbles occur, immediately turn off the gas valve, provide air flow and call emergency services.

It is not allowed to clean the unit while it is running. To clean the housing, you must turn it off, turn off the gas and allow the device to cool.

After this, the body can be wiped with a soft cloth or sponge.

Filling the boiler and heating system with water

Error code 02 indicates that there was an attempt to start the boiler, but there was no water in the system, or there was not enough water. What to do:

1. The appliance is unplugged and the gas supply is cut off.
2. In the bottom of the boiler, among most of the components, you need to find a make-up valve. Turning it counterclockwise opens it, and turning it clockwise closes it.
3. When the tap is open, you need to monitor the readings of the device to determine the pressure value. You should close the tap when it shows 1.3 - 2 bar.
4. Now the boiler is reconnected, gas is supplied and the start-up is carried out.

Don't worry if error 02 occurs again. This may be caused by the fact that after bleeding the air (which is done automatically at start-up), the water level is again insufficient. The filling operation must be repeated.

Water drain from the boiler and hot water supply system

If the boiler is not intended to be used for a long time (especially during winter), it is recommended to drain all water from the heating circuits and DHW. What to do:

1. The device is de-energized and the gas valve is closed.
2. The valves of the heating system (2 pcs.) and cold water are closed.
3. The tap that is used in most cases is opened (above the sink, for example) and hot water is drained from the system.
4. The tap in the DHW system is closed.
5. A plug is opened at the bottom of the housing and the water from the heating supply is drained.

Water drainage may be required during system maintenance.

Cleaning the heating water filter

Filters collect all the impurities present in the water mass.

Sometimes they need to be cleaned, for this:

1. Remove water (see previous paragraph).
2. Wait for the equipment to cool completely.
3. A filter is located not far from the drain plug. To remove it, first remove the mounting bracket, then pull out the filter itself.
4. It must be washed under pressure with drinking water.
5. Then the assembly is performed in reverse order.

If you do not clean the filters in a timely manner, the boiler will become very hot.

Potential breakdowns and how to fix them

Navien error codes:

• 01 – overheating (check if the pump does not stop working and if the filter is clogged).
• 03 – no gas (check if the tap is open).
• 04 – incorrect flame signal (check the serviceability of the gas valve, replace the electrodes or board).
• 05 – 06 – Short circuit on the temperature meter or open circuit.
• 09 – failures with the fan.
• 10 – failures with smoke removal (check the functionality of the fan, whether the chimney is clogged, the connection of the fan tubes is correct, gusty wind could also be the cause).
• 013 - Short circuit on the OM flow meter.

If the boiler does not give any errors, but does not stop working significantly worse, the reason may be a clogged filter or an airy system.

Navien boilers, like any other equipment, require serious care and proper handling. Constant checks and warranty monitoring can help avoid problems.

Double-circuit wall-mounted gas boiler Navien, reviews, connection

For several decades, the Navien gas boiler has been perceived by experts as the most practical solution to all problems associated with hot water supply and heating of residential and other premises. In modern private housing, such devices can undoubtedly be called an ideal way out of the situation, as a result of which such devices are increasingly being installed as an additional option in apartment buildings.

gas boiler Navien Ace

1. During the operation of this device, there is no need to allocate a separate boiler room for it. In other words, such a device can be safely installed directly in the kitchen.
2. The funds you spend installing a Navien Ace wall-mounted gas boiler will fully pay off within a year of active use of such devices, since they ensure extremely economical fuel consumption.
3. Modern heat generators are equipped with a multi-stage safety system that provides the ability to protect them from overheating in the event of malfunctions in the operation of the water pump. It should be noted that the device automatically turns off the burner if the gas supply is completely interrupted.
4. All modern models of gas boilers are equipped with a specialized external temperature sensor and the latest electronic components, which ensure that the heat level is constantly maintained at the required level and allows optimal adjustment of the heating intensity.

This is why Navien gas heating boilers have become so widespread today. You can read reviews about these devices on a variety of resources, and you will undoubtedly be convinced that they are almost always positive.

Almost every Navien floor-standing gas boiler is specially equipped with a separate gas supply system, as a result of which it is supplied both for heating the room and for heating water, so the hot water supply system can be used without any damage to heating efficiency.

In the automatic control system of circuits, which are equipped with Navien gas boilers, technical characteristics have priority in the direction of hot water supply. Thus, as soon as the user opens the water supply tap, the heating circuit is completely turned off, and the burner begins to function solely to support the hot water supply so that the water can be heated in flow mode.

If you need to ensure a constant supply of hot water in large quantities, then it is best to use a specialized integrated boiler in combination with a double-circuit gas boiler, since with its help you can eliminate prolonged shutdowns of the heating circuit, which will always allow you to maintain the required temperature in your room. apartments.

Among other things, it is worth noting the fact that these special types of boilers provide a constant supply of hot water of 70 liters, and their storage tanks have specialized protection against scale and are able to function normally even with minimal water pressure.

If you find that the hot water consumption is too high, then in this case it will be possible to additionally connect a specialized indirect boiler to the double-circuit boiler, the volume of which can be up to 1000 liters. Often, the boiler connection manual contains instructions for operating the Navien gas boiler.

Features of Navien boilers

It is worth noting one more advantage that Korean Navien gas boilers have. Reviews from consumers often indicate that wall-mounted boilers are small in size and have sufficient throughput for most apartments, as a result of which it is simply impractical to install floor-standing equipment in such rooms.

This will have virtually no effect on the performance of such devices, especially since almost all modern manufacturers are trying to minimize the total mass of the heat generators used in their devices in order to ensure the versatility of their equipment and the ability to install it even in small rooms.

If we talk about what are the main advantages of gas boilers over solid fuel ones, we should highlight, at a minimum, their productivity and efficiency. In this case, there is no difference whether we are talking about the use of liquefied or natural gas - in any case, the operation of the Navien gas boiler will be much more economical and will pay for itself after a couple of years of active operation.

How boilers work

The technical design of wall-mounted devices includes the following elements:

• burner;
• frame;
• a water pump designed to circulate water;
• expansion pump;
• heat exchanger

The connection diagram for the wall-mounted double-circuit gas boiler Navien is extremely simple: during the installation of the boiler, it is quite enough to simply connect the pipes to the mixers, and also bring them to the entrance to the heating system.

All modern boilers differ from each other depending on which burner they use. If we are talking about boilers with an open burner, then such devices require the installation of a specialized chimney, which operates on the principle of natural draft. In this case, oxygen for the burner is taken from the room in which the boiler is installed, as a result of which it will be necessary to ensure a constant supply of fresh air.

It often happens that when a person does not follow the operating rules when using a Navien gas boiler, the message “Error 03” appears on the indicator, but this problem is often quickly solved by qualified specialists.

The design of a closed burner involves the use of a specialized coaxial chimney, through which oxygen is supplied and various combustion products are removed. Such systems are activated by forced draft through a fan, which is initially built into the boiler structure, and the pipe is vented outside through the wall.

In the process of choosing a suitable boiler, you will need, first of all, to correctly calculate the boiler power, which is measured in kW and determined by the possible heating area of ​​the boiler. Moreover, before installing the Navien gas boiler, make sure that when heating every 10 m2 of living space, the boiler spends approximately 3 kW of power.

It is best if the heat generator has several outputs and inputs at the same time, especially if you decide to buy such a device in order to provide heating and hot water supply in a country cottage. By using multiple outputs, you can provide the ability to install additional components and devices, among which, in particular, pool heat exchangers, indirect boilers, water floors and much more should be noted.

When deciding on ignition, experts recommend paying attention exclusively to electronic ignition, since in this case you will not have any need to approach the boiler to activate it - you can simply activate the automatic system or turn on the device remotely.

Among other things, piezo ignition does not have a constantly burning ignition device, which can cause malfunctions of the Navien gas boiler and affects the overall safety of using such units.

To protect against surges, it is best to ensure that the boiler is initially equipped with a specialized voltage stabilizer, which will allow you to repair Navien gas boilers less often.

It is worth noting the fact that it is best to use boilers with additional operational reliability, since any errors when interacting with gas can lead to disastrous consequences.

In particular, it is worth noting several main functions, the action of which is aimed at preventing danger.

1. Flame sensor. Using this device, the attenuation of the fire is determined, and if this happens, the automation is activated, which completely turns off the gas supply.
2. Lockout thermostat. If the water overheats, this situation is detected by the sensor, and it sends a signal to automatically turn off the gas supply.
3. A shut-off device that is triggered when the coolant level is insufficient.
4. Blockers that are activated when the gas supply is completely stopped, as well as when the water supply is turned off and voltage drops.

All these types of systems are designed to provide the most effective protection of a residential complex from all kinds of explosions or fires, therefore, if the above parameters are present, the gas boiler you install will in any case maintain trouble-free operation for many decades, successfully heating your home.
