Among domestic heating equipment, a special place belongs to BaltGaz products. It compares favorably with quality comparable to the best European models, competitive price and characteristics inherent exclusively to Russian-made heaters.

Neva Lux 7211

Wall-mounted heating boilers of the Neva and Neva Lux series are in constant demand among Russian consumers. These are high-tech units made using the latest technologies and the most modern materials.

Error E1 - no flame

The ignition clicks for about a minute, the burner does not ignite.
The electronic control unit does not see the presence of a flame and the column goes into emergency mode. Reason #1.

Presence of air in communications. If the column is idle for a long time, or after its installation, the pilot burner will operate only after air has been removed. The system should be purged by constantly turning on the column. Since ignition lasts no more than a minute, after completion you should reopen the water tap until ignition occurs.

Reason #2.

There is no gas in the cylinders or the tap on the descent to the column is closed. Fully open the shut-off valve. Check LPG gas cylinders. Replace them if necessary.

Reason #3.

There is no contact between the block and the flame sensor. The contacts coming out of the electronic unit should be serviced, if necessary, cleaned, pressed for a good connection, and worn ones should be replaced.

Reason #4.

Flame sensor outside the flame zone. Adjust the position of the flame sensor so that its electrode is in the gas combustion zone. Make sure that the electrode does not touch other metal components. Clean the electrode from carbon deposits.

Reason #5.

The gap between the spark plug and the igniter is broken. Due to constant heating and cooling, the ignition burner nozzle is deformed, which increases the gap to the spark plug. Once every two years, or during regulated maintenance, the gap should be adjusted to 4...5 mm.

e1

Error e1. This malfunction indicates low fluid pressure in the heating circuit.

The reasons may be as follows:

• The heating circuit has become airy or the pressure has dropped to its minimum point. Increase the fluid pressure in the system, remove air from the heating circuit.
• The bypass valve is installed incorrectly or is faulty; to check, follow these steps: set the boiler to heating mode, then close the shut-off valve to the heating circuit.
  The bypass should redirect the liquid not into the heating circuit, but pass it through the bypass line (at the same time it will heat up). And, if it is faulty, replace it with a new one, installing all the taps in the position in which they were before the check.
• Pump failure. It is necessary to remove it from the device, disassemble it, wash it, and clean it of accumulated deposits. If this does not work, replace it.
• There is a breakdown in the electrical circuit of the pressure sensor.
  Using a multimeter, test the circuit for an open; if found, repair it. DHW sensor Visually check all contacts and connectors. If this does not give the expected result, replace it with a working device. Occurs often in Neva Lux 2073.
• A slow-moving rod or sticking of the measuring device rod in the heating circuit, the cause could be a failure of the membrane on the flow sensor.
  To begin, remove this sensor from the device, turn the boiler (pump) on and off, in a similar way you can remove the boiled rod. If this does not work, check the condition of the membrane; if it is worn or deformed, replace it.
• There is a malfunction in the flow sensor, or the integrity of the connecting wire is broken. Perform an electrical circuit check and also check the connections of the controller board connectors. If the problem persists, replace the flow sensor. Typical for the Neva Lux 2083 model.
• Failure in the electric motor of the three-way valve. Repair is not possible, complete replacement is necessary.

Features of operation

Before you start using Neva Lux, read the manufacturer's instructions. Yes, the boiler is easy to use, but following basic rules will help extend its service life and protect your home from unexpected problems.

On the outer cover of the housing there are two regulators - for heating and domestic hot water. Setting to “zero” means excluding the circuit from operation. Nearby is a reset button.

The operating algorithm of Neva Lux is based on the “set it and forget it” principle. It is enough to set the temperature once, and its parameters will not change under any circumstances.

If the electricity goes out, the mode will be restored automatically when it appears.

The control program includes an economical mode, which allows you not to turn off the heater during short-term departures. It is possible to program several days in advance. The remote control provides additional convenience to the user.

When gas supply stops, to prevent defrosting of the heating system in winter, a mode is provided to prevent freezing of the coolant. In this case, water circulates through the system when the burner is not working.

Neva Lux control panel

Connecting external temperature sensors makes it easier to control the temperature. The sensor is installed in the room farthest from the heater. If the air temperature in it drops below the programmed one, the boiler will turn on (burner) and restore the parameter. It is allowed to install 2-3 sensors simultaneously in different places.

An outdoor temperature sensor also makes the task easier, but its inclusion in the circuit is not recommended due to various types of interference in the form of solar heating, wind, or air with high/low humidity. Such a sensor is installed in proven places that eliminate or minimize the impact of “harmful” factors.

Gas boiler NEVALUX-8224 is a wall-mounted double-circuit gas boiler with an open combustion chamber and an LCD display designed for apartment heating and hot water supply in multi-storey buildings, as well as in private cottages with an area of ​​up to 240 m2. The use of one bithermic heat exchanger for heating and hot water supply allows reducing the cost of the device while maintaining all consumer functions.

The NEVALUX-8224 gas boiler is significantly different from the previous generation NEVALUX boilers. The combustion chamber is water-cooled, which increases the service life and increases the reliability of the boiler. The primary heat exchanger, responsible for heating the water, is designed on the basis of pipes of increased diameter, which significantly slows down the process of scale formation, extends the service life and reduces the frequency of service.

The external cladding of the boiler is made of metal-plastic with a triple degree of corrosion protection, consisting of primer, galvanization and enamel coating. The metal-plastic cladding ensures reliable operation of the boiler for several decades.

There has been another improvement in the appearance of the boiler - a new control panel. Boiler control has reached a modern level, has become intuitive and more informative. The function of connecting a remote control, an external street sensor, and a personal computer has been added. An outdoor temperature sensor will provide information to the boiler for more economical operation, and connection to a PC will simplify service and diagnostics of the boiler. The Italian-made electronic board that organizes all these functions is optimized for Russian operating conditions. These innovations will allow the boiler to ensure stable operation and increased safety.

Distinctive features of the gas boiler NEVALUX-8224:

• Two separate heat exchangers for heating and domestic hot water circuits

Piping for heating equipment

The lineup

The manufacturer's product line includes several wall-mounted Neva Lux models with compact dimensions, the power of which varies from 12.7 to 30 kW.

The model is initially intended for use in apartments and small houses with an area of ​​up to 110 square meters. m. This unit has two circuits and a closed chamber, with a power of 12.7 kW. Equipped with a bithermal heat exchanger and an electronic ignition system. Capable of heating up to 9 l/min when using DHW. The use of a common heat exchanger led to a reduction in cost while maintaining functions. Features low gas consumption.

Heater diagram Neva Lux 7218

• The power of this double-circuit heater with one bithermic heat exchanger is 18 kW. Designed for living space up to 180 sq. m. It features a more powerful pump, as a result of which the heating rate of hot water reaches 14 liters per minute.
• A double-circuit boiler with one bithermal heat exchanger is designed for rooms with a heating area of ​​up to 240 sq. m. m.
• It differs from the above model by connecting a remote control, an outdoor temperature thermostat and a personal computer. There are two heat exchangers, one of which is copper and the other is made of steel plates. Designed for 240 square meters of area. Runs on liquefied gas. Equipped with a closed chamber, cooled by water and a forced smoke removal system.
• This double-circuit model with an open chamber is intended for use in heating systems of apartments and houses with a total area of ​​up to 300 sq. m. m. Equipped with one bithermic heat exchanger.
• Neva Lux 8624. This model, with a power of 24 kW, is equipped with two heat exchangers and an open combustion chamber. The Italian electronic board is adapted to our conditions.

As you can see, along with proven budget models, the manufacturer supplies their updated versions at a higher price. The firebox of the latter (the designation begins with an eight) was water-cooled. The heat exchanger for heating water is made from tubes of increased diameter, which slows down the appearance of scale.

The external cladding is made of metal-plastic. Three layers - primer, galvanization and enamel - reliably protect the boiler from corrosion. They feature improved control panels.

Design and principle of operation of Neva and NevaLux speakers

The BaltGaz line includes several instantaneous gas boilers, differing in their operating principles and internal design features. All manufactured equipment can be divided into several groups:

• Type of ignition - there are semi-automatic and automatic models. The first ones (4011, 5111) during operation use a constantly burning wick, ignited by a piezoelectric element. The second, with automatic ignition, runs on batteries. The gas is ignited by a spark supplied to the burner device.

Using modulation - gas instantaneous water heaters Neva and Neva Lux operate using hydraulic (5111, 5611) and electronic (6011,6014) changes in water heating power. There are models without automatic adjustment of combustion intensity.

The design of Neva and NevaLux geysers is constantly being modified and modified. New models are being produced, the design of which is adjusted taking into account the wishes of consumers.

The technical characteristics of water heaters manufactured by Baltgaz are described in detail in the following table:

How to light a device with electronic ignition

Before turning on the column, you must make sure that there is a flow of clean air in the room, since oxygen is burned during operation. All Neva devices are produced adjusted to a specific type and gas pressure - real G20, liquefied G30 with a corresponding pressure of 1.3 kPa and 2.9 kPa.

For example, consider how to light

gas water heater Neva 4511 and Lux ​​5611 with electronic ignition from LR20 batteries with a voltage of 1.5 V (additionally, take a look at the publication - why the
Neva water here).
These devices have continuous hydraulic flame modulation. The front panel is equipped with an observation window, gas and water adjustment knobs, and a digital monitor. To turn it on, you need to install the batteries in the battery compartment; you will understand in advance that the contacts of the batteries and the battery compartment are not oxidized.

Neva Lux 4511

Open the shut-off valves in front of the device. Then turn the toggle switches to a small position. If ignition occurs for the first time, or after a long period of inactivity of the device, air should be removed from the system. To do this, you will need to open and close the water valve a couple of times to continue ignition, since spark discharges last about seven seconds. After switching on, being careful not to get close to the inspection window, you must make sure that the flame burns evenly, blue, without yellow edges that appear if the burner is clogged.

The stream is adjusted using a knob; if the water meter unit has low pressure, it must be set to a small position, and at the outlet of the device you will receive a small, average amount of water. If the pressure in the middle of the line is high and you need a considerable amount of water, the regulator must be set to the maximum value. If, at low pressure, you set the maximum value, then the column

will go out, it may also go out if the tap is opened to a small flow. In order for it to light up again, you need to turn the regulator to a small position or increase the flow pressure.

You can adjust the temperature using the gas control knob - the maximum position increases its flow rate and the temperature of the outlet stream, a small position - vice versa. Plus, you can adjust the temperature of the outgoing stream by changing its flow rate with the hot water valve - opening it more, the temperature will decrease, tightening it, it will become higher.

But we must not forget that the resulting temperature is exhausted by the power of the device, with a large flow rate, especially in winter, as a rule, it has a low temperature.

When setting the flow adjustment toggle switch to a small position, and the gas regulator to the maximum, the heat exchanger will overheat, the column

will go out because the overheating meter will trigger. To turn on the device again, you need to close the hot water tap, then open it again. Using toggle switches, reduce gas consumption or increase water consumption. Overheating of the heat exchanger leads to the appearance of scale and noise during operation. This reduces the efficiency of the device and reduces the output flow; therefore, it is not recommended to dilute a hot stream with a cold one, since the operating life of the device is reduced. As a matter of user experience, the temperature should not be set above 60 degrees.

To turn off the unit, just close the tap and make sure that the main burner has gone out. If it is turned off for a long time, you should close the gas and water shut-off valves.

This code means that the water temperature has exceeded the permissible value

It is strictly recommended to connect heating boilers through a stabilizer (for the boiler) or a UPS; this will save you from unnecessary costs for replacing the control board.

Checking the polarity in the plug-socket connection: turn the plug 90 degrees and insert it back into the socket or stabilizer.

Check grounding: the main cause of errors installed in apartments.

In the private sector, circuit testing is carried out with a device - a megger; when measuring resistance, R should show no more than 4 ohms.

The simplest testing of a pump is performed by turning its shaft manually and assessing the condition of the mechanical part based on how easily the shaft turns.

Low coolant pressure in the system: if the boiler pressure gauge needle leaves the green sector and turns to red), it is necessary to increase the pressure to the minimum threshold of 1 Bar

The make-up valve is located at the bottom of the heating installation, next to the connection pipe for the cold water pipe.

It opens counterclockwise until the characteristic noise of the incoming liquid appears; do not forget to close the tap in the reverse order, otherwise the pressure will creep into the reverse red zone and the relief valve will begin to operate (water will flow).

Leakage: easy to identify by walking around the house, looking at puddles on the floor

Focus on pipe connections, heating radiators, mounted appliances

The water supply tap in the system is closed: you need to check the position of the controls of the taps, valves on the main line and bypass. Most likely, the heating circuit pipe is blocked in some area.

The coarse filter on the main line is clogged: it gradually becomes clogged with sediment from the heating system, and if the mesh has not been washed for a long time, dirt can cause an error.

The pressure switch is faulty: the sensor is initially set to a value of 0.45 bar. and when the pressure in the heating circuit increases, its contacts close, a switch-on permission signal is sent to the board, a drop in pressure leads to a break in the circuit, and an error is generated - blocking the operation of the boiler in emergency mode.

The safety valve has failed.

Failures in the gas supply to the house: often the gas supply pressure on the main line decreases and the boiler does not return to operating mode. The check comes down to igniting all the burners on the stove at maximum mode. Flames with a characteristic shade will indicate the absence of problems with the fuel supply, and their intensity and stability will indicate the constancy of the pressure and its normal value.

You also need to check:

1. The position of the shut-off valve controls: the gas supply valve to the house may have been accidentally turned off or the shut-off valve was activated during a power outage.
2. Serviceability, condition of technical devices: meter, reducer (with autonomous gas supply), main filter, filling level of the tank (gas tank, cylinder group).

Resistance between pins 1 and 3 – 6.5; 1 and 4 – 7.4 (for SIT SIGMA 845048 block).

If there is a discrepancy, the gas valve is replaced (turn-to-turn short circuit). If R = ∞ – open circuit, R = 0 – short circuit.

The electronic board is faulty: a fault in the electronic circuit also causes an error to appear in the boiler.

Defects are identified by inspection for deformation, melting, breaks, condensation, etc.

The new board may not be configured correctly.

If the cause of equipment failure is the board, contact the service center indicating the alphanumeric marking of the node.

Typical faults

Boiler error codes can be found in the operating instructions

Any complex equipment fails after prolonged use. The main indicator of reliability is quick commissioning through repairs with the elimination of typical faults. A warranty card is issued for any heating equipment and installation work. Therefore, calling a technician during the warranty period will be free - the manufacturer’s warranty will cover equipment malfunctions, and the installer company will eliminate installation defects.

A list of major equipment errors can be found on a special display.

Error 01

In the Neva Lux boiler, this type of error means that the device cannot be ignited.

1. Check valve opening and gas supply. If necessary, call the gas service.
2. The gap between the spark plug and the burner should be 5 mm. Adjust.
3. Isolate the breakdown site when the candle is broken.
4. Clean the dirty spark plug.
5. Ring the ignition transformer circuit.

Error 03

An uninsulated chimney allows condensation to accumulate, which impedes operation.

Accumulation of condensate in pipes causes error type 03.

• The chimney is clogged or its structure is damaged.
• Depressurization of the pressure switch tube or disruption of its electrical network.
• Fan failure.

Error 04

Error 4 indicates insufficient pressure in the heating circuit. This interferes with the functioning of the components and contributes to overheating of the boiler.

1. Increase the pressure in the circuit.
2. Remove the air lock using the air bleed valve.
3. Check the pressure sensor.
4. Clean the pump and inspect the connections.

Installation and connection

Before you begin installing and connecting the Neva Lux boiler, think over and sketch out a diagram. The project determines where and how the unit will be inserted, taking into account subsequent piping, and also creates a connection diagram to the electrical network.

The diagram itself will be useful in the future when replacing or repairing the unit. You can install and connect the Neva Lux boiler yourself. There is nothing complicated there. The main thing is to comply with the operating conditions set out in the manufacturer’s instructions. But it’s better to trust the professionals. Thanks to their experience and special knowledge, they will accurately determine the required list of strapping elements and carry out the work at the proper level.

On average, the installation process takes 3-4 hours. This is an approximate time. Installing additional thermostats and connecting to the control system may take longer.

Neva Lux boilers are easy to install because they are ready-to-use safe units.

In addition, to such boilers you can connect an indirect heating boiler, a forced smoke removal fan, or a room thermostat, thanks to which the equipment is highly economical.

The company's new product is the Turbo boiler

As the Lux models were used, both negative and positive consumer reviews accumulated. Over time, all the necessary adjustments resulted in the production of a separate series of heating equipment.

Neva Turbo boilers are, in fact, a modified version of the already familiar Lux modification, taking into account the shortcomings of previous versions. The models have the following technical characteristics:

• Closed combustion chamber - forced air supply is carried out using fans. Smoke removal occurs using a special device through a coaxial chimney.

Automation - gas double-circuit mounted boiler Neva Turbo, a station completely ready for operation. Heating control and safety are achieved using a multi-level system of sensors and valves. There is a self-diagnosis system that automatically performs tests and displays fault messages on the LCD display.

Controls: Simple push-button controls. Using a simple regulator, you can set the required temperature, provided that the programmer is installed, you can set operating conditions for several days or a week. A room thermostat is supplied as an additional package. The sensor sends a signal to turn off the heating when the room is heated to the required temperature.

Turbo boilers are energy-dependent. The boiler is powered by connecting to a regular 220 V mains voltage. For stable operation, you will need to install a UPS and a generator.

Ease of maintenance and operation

Regardless of the chosen model, installation of a mounted boiler is quick and without the need for additional costs. The manufacturer places the main emphasis on ease of installation and subsequent operation. Therefore, the company’s boilers, in fact, represent a station ready for operation.

It is enough to connect the installation to the heating and power supply system and start heating your house or apartment. In practice, provided the heating system is already ready, all work takes about 3-4 hours.

After installation, there is no need to worry about the safety of the station. The sequence of operation of the automation completely eliminates the possibility of gas leakage and the creation of an emergency situation, even if an unplanned power outage occurs.

The main differences between Neva boilers

Simple design and operation make it possible to distinguish Neva boilers among all domestic heating equipment. Today, in terms of their characteristics, boilers are in no way inferior to foreign equipment and have a more attractive price.

The Turbo modification provides economical gas consumption and, subject to proper operation, fully pays for itself within a few years.

Main technical characteristics and features of Neva company equipment

Please note that wall-mounted gas boilers on the market are available with open and closed combustion chambers. What does it mean? In the first case, combustion products are removed naturally, through the chimney to which the device is connected. The air required for normal gas combustion is taken from the room.

In the second case, the gas boiler is connected to a coaxial chimney, the design of which is made according to the “pipe-in-pipe” principle. Through the inner pipe, combustion products are forced out, thanks to the built-in fan, and air is supplied through the outer pipe, which comes from outside the room.

Wall-mounted double-circuit gas equipment is capable of performing two tasks aimed at heating the coolant and sanitary water. Heat exchangers are installed separately, one is designed to heat the coolant, the second is designed to heat sanitary water.

Household appliances of this type are distinguished by a wide power range, which allows you to select a unit for installation in an autonomous heating system for a house of any size

When choosing a device, it is important to take into account that 1 kW is required for normal heating of 10 m2. So, if a house, for example, has an area of ​​200 m2 in which there is a need for hot water supply, then in order for the system to operate stably, efficiently and economically, you will need to buy double-circuit gas boiler Neva of any model with a capacity of 24 kW

in which there is a need for hot water supply, then for the system to operate stably, efficiently and economically, you will need to buy a Neva double-circuit gas boiler of any model with a capacity of 24 kW.

Design features of the Neva boiler

Despite the fact that the Neva wall-mounted boiler is small in size, its design contains everything necessary for stable and high-quality operation of the equipment. Therefore, having chosen these heating boilers, you will not need to buy a separate circulation pump or expansion tank, the task of which is to promptly remove air from the heating system. According to experts, the built-in expansion tank can significantly increase the safety, reliability and stability of the heating system.

The main advantage of a built-in expansion tank from a remote tank is that there is no need to constantly check the coolant level; the equipment will do this for you. In addition, since there is no need to install an expansion tank, it is possible to significantly save on the installation of the heating system.

All models of gas boilers presented by Neva are equipped with pressure gauges, which are installed on the equipment panel

It is important to know that as the temperature increases, the pressure in the system increases and vice versa. The system should be replenished if the pressure drops below 1.5 atmospheres. Note that Neva wall-mounted appliances are able to continue to operate effectively at reduced gas and water pressure

Note that Neva wall-mounted appliances are able to continue to operate effectively at reduced gas and water pressure.

Let's return to the contours of the device, namely the one that is responsible for heating sanitary water intended for everyday needs. So, for its manufacture, stainless steel is used, the advantage of which is its high resistance to corrosion, thereby increasing the durability of the device.

If you want to extend the operational life of your equipment, it is recommended to install a filter on the water supply pipe through which water is supplied to the boiler, with the help of which the water will be purified and softened. Shut-off valves should be installed in front of the filter and on the return line, which will allow equipment maintenance and filter replacement to be carried out without unnecessary difficulties.

Other faults

If the device does not turn on:

• There is no power, contact the supply company.
• The fuse has burned out, you need to replace it, it is located on the board.
• A leak inside the boiler, which led to liquid getting onto the board and causing a short circuit. Dry the board on the battery or with a hairdryer and let it dry for two days.

Popping sounds during operation:

• Adjust gas pressure.
• Poor air flow in the room, clean the chimney duct, open the window or door while the boiler is operating.
• Accumulation of a large amount of soot in the burner group.

There is a smell of gas:

• If there is a gas leak, you must immediately contact the gas service.
• Low fluid pressure, contact water supply.
• If the heat exchanger is clogged, clean it using special chemicals.

Error E8 no traction

The column turns off after 2..5 minutes of operation. Restarting becomes possible only after cooling down - 2..3 minutes.

Reason #1.

Lack of draft in the chimney. Clean the chimney.

Reason #2.

Soot on the heat exchanger. Increased accumulation of soot on the heat exchanger, which prevents the passage of carbon monoxide into the chimney. To resolve the problem, the column must be serviced.

Reason #3.

The traction sensor is faulty. The traction sensor works to break. Over time, the sensor becomes very sensitive to vibrations and may turn off the column during heating. Therefore, if this error occurs, the sensor will be checked for functionality.

Air supply and flue gas removal (errors 6**)

The system for supplying air and removing flue gases generated during the operation of a gas boiler can be natural or forced. Therefore, some errors may not occur for different devices. But we'll look at them all.

Error No. 601. The draft thermostat is triggered when the contact is broken or the smoke exhaust thermostat is internally damaged. It is also possible that the air vent system is clogged.

Error No. 602. The same thing, only for VMC type combustion chambers.

Error No. 604. The Hall sensor is faulty (it needs to be replaced) or the speed of the fan blades is low (it needs to be cleaned or also replaced).

Error No. 607. The contacts of the controlling pneumatic relay were closed before the fan turned on. This detail confirms that there is sufficient draft before ignition. To eliminate early closure, you need to carefully remove the pneumatic relay and blow out its tubes, removing dirt or condensation. If this does not help, the part will have to be replaced.

The air relay is connected to the exhaust chamber with a silicone tube. Sometimes there is a condensate trap there. If the problem is with the pressure switch, then first you need to check the integrity of the tube

Error No. 610. Thermal fuse contacts are open. This part needs to be replaced.

Error No. 612. Same as error No. 604, but on early Ariston models.

How to turn on the Neva column

Automatic water heaters turn on independently. When the water supply tap is opened, the ignition unit sends a signal to produce a spark. The gas supplied to the burner ignites. After closing the water consumption tap, the column turns off.

Semi-automatic instantaneous boilers are distinguished by the fact that a pilot burner is used for ignition. To bring the column into working condition, you need to light the wick. For this purpose, a piezoelectric element is provided in the internal device. After igniting the pilot burner, the water heater continues to operate in automatic mode.

You can adjust the Neva column using water flow and gas pressure regulators. If the device has a modulating burner, the consumer sets the heating temperature, after which the electronics changes the combustion intensity depending on the pressure in the pipeline and other operating parameters.

Model range of boilers Neva Lux

The luxury series, well known to consumers, is divided into two categories:

1. For heating an apartment or house, a wall-mounted single-circuit Neva boiler is best suited. Instead of a DHW circuit, you can install an indirect heating boiler. The modulation burner installed in such boilers, thanks to automatically changing combustion intensity, makes it possible to achieve high efficiency of the equipment. The 8618 single-circuit gas boiler attracts buyers with its low cost and simplicity of design, as well as the absence of complex energy-dependent automation.
2. The double-circuit boiler 7218 luxury series from the Neva company has extremely positive reviews due to its practicality and efficiency. Modern automation allows you to accurately monitor the temperature of the coolant and water in the DHW circuit. In addition, some models provide additional outlets for the underfloor heating system. The installed automation is capable of controlling each circuit separately. The most popular models are 7218 and 8224.
