Operation of the Navien Deluxe gas boiler: installation of double-circuit wall-mounted models with your own hands + reviews from owners

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?

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.

Recommendations for use

For long-term and uninterrupted operation of the boiler, the operating rules and manufacturer's requirements must be observed.

For example, during a break in operation (2-3 days), you should not turn off the device from the network, as this will invalidate the operation of the icing system. Do not allow ice blockage to form. If it does form, then you should warm it up with a hairdryer.

If there is a long period of downtime, for example in the winter, it is worth draining all the water. There is no need to allow the circuits to freeze. This is quite dangerous and detrimental to the system.

It is recommended to clean the filters regularly. This procedure will protect the boiler from overheating and increase its service life.

Setting up a Navien boiler yourself is, of course, saving money and time, but if you have any questions or doubts, you should still seek help from specialists. In addition, the installation of heating equipment must be carried out by experienced craftsmen. This will give you confidence in its reliability and safety.

Design features of Navien gas boilers

Manufacturers of Navien produce devices of different capacities, floor-mounted, wall-mounted and with a hot water supply function. They can be connected both to a centralized line and to gas cylinders. The units have a modern appearance that allows them to fit into any home interior. Navien gas boilers are equipped with a safety group, which includes:

• modulating turbocharging;
• protection against coolant freezing;
• SMPS chip that protects against power surges;
• temperature sensor control panel, which allows you to adjust the operation of the unit to certain circumstances.

The most common model of Navien gas units is Deluxe, so let’s look at them in more detail.

Power-on problems

There may be several reasons for such a malfunction.:

• There is no voltage in the network (or it has decreased too much, it has become less than 150 V).
• No gas.
• The boiler is blocked by a protection system that was activated due to a critical error (overheating above 98°).

Other reasons for failure may also occur . First of all, you should check the voltage in the network.

The boiler is capable of compensating for fluctuations of up to 30%, but with more significant changes, it simply will not start. You can solve the issue by using a separate outlet and installing a stabilizer.

If all possible causes have been checked and eliminated, but the boiler continues to be silent, you should invite a specialist . Perhaps the cause was a failure of the control unit, a breakdown, or another serious problem.

You should not attempt to resolve the issue yourself; this may cause the final destruction of the unit.

Doesn't start for a long time

The boiler is started when certain conditions are reached. If the temperature or pressure of water (OB, DHW) is within the specified range, heating will not start until it cools down .

A possible cause may also be partial clogging of the water filter, which slows down the flow and changes the circulation mode. It may be difficult for the circulation pump to operate if it is clogged with lime deposits or small debris.

Installation and connection procedure

Let us immediately note that the installation and connection of any model of Navien gas boiler, as well as its first start-up, must be carried out by a specialist from an authorized service structure.

Otherwise, the manufacturer will not fulfill warranty obligations. However, the owner should know how the process is carried out in order to control the work of the hired contractor.

Providing conditions for installation

South Korean equipment for heating coolant and hot water can process both main gas and liquefied gas mixtures. The blue fuel options available for use are indicated on the plate. It is attached to the right side of the body.

Information about what type of gas can be processed in the Navien boiler can be found in the table on the right panel of the housing. Using gas that does not correspond to the declared one may lead to failure of the unit or an accident.

To connect the boiler, you will need to connect a power supply line to the location. The device cannot be connected to the electrical network through adapters or extension cords.

Requirements for the electrical line for the boiler:

• The power supply source for operating a boiler of this brand must have the following parameters: 220V, 50Hz. Deviations from these standards may result in either fire or loss of performance.
• It is prohibited to connect any electrical equipment parallel to the boiler to the source. Failure to comply may result in a short circuit.
• The socket should be located 30 cm from the heater body.
• The unit must be located at least 60 cm away from electrical appliances of all types.
• The boiler body must be grounded.

In the room intended for the location of gas equipment, a flawlessly functioning exhaust and supply ventilation system must be organized.

The window should have a transom that can be easily opened for ventilation. The door should have a ventilation gap or grille at the bottom.

It is not allowed to locate gas equipment in rooms with a characteristic high level of humidity: in bathrooms, in swimming pools, in showers and bathhouses. Dampness and insufficient air flow interfere with the normal operation of the boiler. In addition, its operational life is reduced.

Boilers cannot be installed in open areas. They are not intended for contact with atmospheric negativity. It is prohibited to place where explosive and flammable substances, as well as bulk building materials, are stored.

Choosing a location

In most cases, wall-mounted gas boilers are located in kitchens or hallways that have a window or only a vent for ventilation.

To install floor-standing models, boiler rooms are installed, separated from residential and functional spaces in the house. In any case, sufficient space should be provided for convenient maintenance and repair of the unit.

Let's consider the rules for choosing a location for a wall-mounted gas appliance as the most common solution for our compatriots:

• Hanging is allowed on a wall made of non-flammable building material. If the wall material is capable of igniting and sustaining combustion, the surface must be lined with a non-combustible finish.
• The unit must not be located near emergency exits or staircases.
• There must be at least 0.6 m between the opposite wall and the front panel of the gas equipment. A similar distance must be maintained between the boiler and any electrical appliances.
• Between the side panel of the case and the nearest structure or piece of furniture you need to leave 0.2 m.
• There should be 0.8 - 1.1 m between the floor plane and the lower edge of the unit hung on the wall.

To mount the wall-mounted model, it is advisable to find a place on a load-bearing wall. If the strength of the wall is in doubt, it should be strengthened. The boiler is fixed with anchor bolts.

If there is a suspicion that the heater will make excessive noise during operation, it is recommended to use buffer substrates on the wall made of non-flammable material.

Connecting the speaker to communications

For the gas heater of coolant and sanitary water to operate, the dual-circuit heating device must be connected to communications. We have already talked about laying a separate power line. Everything must be done in accordance with the PUE regulations.

In order to understand the nuances of connecting a gas boiler, you should carefully study its structural structure. Due to the fact that an inexperienced contractor confuses a gas pipe with a water supply branch, a serious emergency situation may result.

Now you need to connect branches from cold water supply systems, gas supply and heating return pipes to the boiler. And you have to remove from it the heated coolant supply line, the hot water supply pipe to the mixers and the chimney.

All stages of connecting a Navien brand gas boiler must be performed according to a diagram drawn up in advance by the gas service with which the contract was concluded and by the plumbers servicing the house. It takes into account the technical features of a particular room and the recommendations of the equipment manufacturer.

Connecting the gas boiler to communications must be carried out by a representative of the organization with which an agreement has been concluded for the supply of blue fuel, inspection and maintenance of gas-using equipment

After installation, all connections of pipes transporting water must be checked for leaks. Both heating and water supply lines need to be tested. Gas pipelines also require inspections, which are simply covered with a soap solution at the connection points to detect leaks.

It is recommended to insulate pipes that are not involved in the heating process. These are partially heating routes and all water supply branches. As thermal insulation, it is better to use foam insulation that follows the shape of the pipe.

All pipelines connected to the boiler must be equipped with taps to shut off the device in the event of a threat or breakdown. The boiler should be connected to a source of liquefied gas through a reducer, and to a group of cylinders - through a gas manifold.

All communications entering and exiting the boiler must be equipped with taps, which are required to shut off the flow of medium in the event of repair or replacement of equipment, as well as in the event of a threatening situation.

Upon completion of the installation operations, the boiler is started for the first time, which must be performed by a representative of the organization supplying you with gas. Then adjustments are made according to your personal preferences and requirements for the indoor microclimate, as well as in accordance with the time of year.

Features of the first launch

The first start-up and adjustment operations are carried out by representatives of the service center, who installed the boiler and connected it to communications. All actions are documented.

The owner of the equipment needs to keep these papers, because they constitute written confirmation for the subsequent fulfillment of warranty obligations.

Before carrying out installation work, a diagram must be drawn up. The contractor must provide the customer with an estimate of the materials he will have to purchase.

For the first launch you need:

• Fill the boiler and the circuits connected to it with water . This is done through a make-up unit located on the bottom of the boiler, equipped with its own tap. They are also used if for some reason the pressure in the gas boiler drops during operation.
• Monitor the pressure during filling . When the pressure gauge shows 2 atm, the tap should be turned off.
• Remove air pockets manually . Next, excess air will be removed from the unit automatically, but for the first time after filling the heating circuit with coolant, they must be eliminated using a Mayevsky tap from each device, starting from the furthest one.
• Replenish the water in the heating circuit so that the coolant takes up the space that was previously occupied by air that had not been removed.
• Bleed air from the circulation pump built into the boiler.

After the above steps, you need to start the equipment by pressing the “Power” button. Then you need to start setting the priority temperature regime for the owners.

If, after filling the communication systems and bleeding the air, error code 02 appears on the display, you need to use the make-up tap to replenish the water. It is also needed to relieve water pressure in the circuits

Specifics of the setup

Navien boilers come with a remote control panel. It is with its help that the settings are made. All commands and modes on the panel are written in Russian, buttons for all functions are accompanied by extremely clear graphic icons.

In the lower right corner of the remote panel there is a button that is used to turn the unit on/off. One press activates the boiler in the mode set by the owner. Pressing again will stop the heater.

To control the boiler and select the appropriate operating program, gas processing equipment from Navien is equipped with remote controls

You can turn on the heating with temperature control of the coolant as follows:

• We find a button on the panel with an icon resembling a battery. Press until a similar symbol appears on the display.
• We select our priority temperature using the buttons with the “+” and “-” icons located in the center of the bottom of the panel. We increase and decrease from 40º to 80ºС in the most familiar way.
• We similarly designate the period during which the coolant will heat up.

Everything is extremely simple. If the “battery” icon on the display is pulsating, then it shows the parameters that we have just set. If it stops blinking, it means it displays the actual temperature at the moment.

In order to set the heating mode with the optimal temperature, you need to find the desired function on the remote control and set the priority temperature

To set the mode according to which the boiler will start/shut down, focusing on the temperature background in the room, perform the following steps:

• We find a button on the panel with an icon resembling a battery. However, now we wait until an exaggerated image of a house with a “thermometer” inside appears.
• We return again to the “+” and “-” buttons to select our priority temperature background in the room. It varies in the range from 10º to 40ºС.
• A flashing house will show us the selected temperature, a non-blinking house will show us the actual temperature parameter at that moment.

Upon completion of all the actions performed, there is no need to press any buttons to save; the settings we selected are automatically saved.

To select the desired water temperature, you need to find the function indicated by the shower head on the remote control and set the desired value. Note! It is prohibited for another person to change the temperature during hygiene procedures.

You need to choose the optimal temperature for preparing sanitary water as follows:

• We find the button for controlling the “Hot water” mode. Press it and wait for a pulsating image of a working shower head to appear in the upper right corner of the display.
• Again we use the “+” and “-” buttons to find the optimal temperature for us. It can be set in the range +30 – (+60)ºС.
• We are waiting for the shower to finish flashing. This means that the boiler automatically saved the set level and switched to operating mode in accordance with it.

If the unit is to be used only in the summer or was purchased for the preparation of hot water, the “Hot water priority” function comes into play. The procedure for selecting it is slightly different from the method described above. The difference is that a double symbol will appear: a shower and a circle of three arrows.

Selecting this mode will force the boiler to heat sanitary water even when it is not in use. Those. the heater activates and prepares water, and after 10 minutes it turns off if no one opened the taps during this period.

If the heated water is consumed, as indicated by an open tap and a drop in pressure, the boiler will always prepare water at the set temperature. It works to heat water only when there is a need for it. If you switch the equipment to another mode, this one automatically stops working.

Navien boilers can only operate to heat hot water. To do this, they need to be switched to the “Priority of hot water” mode (scheme of 3 points at the top) or “Away from home” (scheme of two points below)

You can switch the Navien boiler to a mode that only heats water by using another function. Our compatriots know it under the name “Winter-Summer”. However, it is correct to call it “Outside the Home”. The button to select it is located in the lower left corner.

There is a timer to set the period of continuous operation of the gas unit and turn it off when it is not particularly necessary. It is controlled according to the absolutely simple scheme described above. The range of capabilities of the timer device is designed for an interval from 0 to 12 hours.

What models are included in it?

The Deluxe series includes the following boiler models:

• Deluxe.
• Deluxe Plus.
• Deluxe Coaxial.
• Deluxe Atmo.

The first three models practically do not differ from each other, having only minor differences in the design of the chimney or the amount of gas supply.

The Atmo model is a boiler with an open combustion chamber, which is distinguished by the supply of air directly from the room.

All types of boilers are available in various power options:

• 13k (kW).
• 16k (kW).
• 20k (kW).
• 24k (kW).
• 30k (kW).
• 35k (kW).
• 40k (kW).

Some models are created on the basis of one standard size with software-limited functionality.

Thus, boilers with a power of 24 and 16 kW are of an identical design, but the 16 kW models have slightly reduced power. This gives the units a noticeable power reserve, allowing them to freely overcome load changes and external influences .

Detailed instructions on connecting and commissioning a wall-mounted version of a gas boiler:

Knowing the specifics of installing, connecting and configuring a gas boiler is useful both for independent home craftsmen and for owners who invite plumbers and gas workers to perform the work described above.

Possession of information will ensure the correct execution and proper control of all actions. Then the boiler will work perfectly, will not create problems and will last for an extremely long time.

Navien Deluxe gas pressure values

Device

The Navien gas double-circuit boiler heats the coolant and ensures its circulation in the system.

A gas burner combined with a primary tubular heat exchanger heats the OM flow, which passes through a three-way valve at the outlet.

To obtain a given temperature, a certain amount of cooled return water is mixed in, after which the coolant is sent into the system.

The combustion mode is regulated by the supply of fresh air, which is provided by the fan.

Hot water is heated by a secondary heat exchanger (plate). The operation of all devices is monitored by a system of sensors that signal to the control board about the occurrence of certain problems.

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.

What to do if the aspirated air leaks?

For the Atmo model range with an open (atmospheric) burner, the primary heat exchanger is made of copper.

The appearance of a leak is almost always associated with its destruction. Purchasing a new heat exchanger is not an easy and expensive task, so most often the issue is solved by soldering the fistula .

To carry out repairs, you should contact a technician from the service center, since this requires a qualified specialist who can dismantle the unit, find the fistula that has arisen, solder it properly, simultaneously rinse the heat exchanger and install it in place without damage.

The work is complex and requires the participation of a trained person.
