Service instructions navien gst. An overview of the types of gas boilers is Navien. Key product features

Autonomous heating and hot water supply turn private house into a comfortable home that provides considerable savings and does not depend on the appetites of resource suppliers.

Installing your own boiler allows you to independently adjust the heating mode, based on the need and climatic conditions, and not the average annual schedule for the supply of coolant.

The choice of equipment in the distribution network is extensive, but finding the most successful option is quite difficult.

The cost of European models of boilers is too high, the quality of domestic samples often leaves much to be desired.

Consider one of the most good options combining affordable price and high quality.

Gas Navien boilers are products of the South Korean industrial concern KyungDong NAVIEN.

The company specializes in the production and design heating equipment working on various types fuel - liquid, solid, gas and electricity.

Navien Deluxe is a series of double-circuit wall-mounted gas boilers that replaced the discontinued Navien Ace family.

The design and feature set have not changed much, although some points have been improved and supplemented.

The units supply the coolant (RH) to the heating system and at the same time provide housing hot water(DHW).

Korean developments were carried out taking into account Russian conditions and are specialized to work with unstable parameters in all directions - gas and water pressure, power fluctuations. The equipment fully complies with the norms and standards in force in the territory of the Russian Federation.

Navien boilers are equipped with a special device that compensates for voltage fluctuations in the network up to 30%.

What models are included

The Deluxe series includes the following models of boilers:

• 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 boilers with an open combustion chamber, which are distinguished by air supply directly from the room.

All types of boilers are produced in various options by power:

• 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.

So, 24 and 16 kW boilers 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.

Specifications

Consider specifications Boilers Navien Deluxe:

There may be some changes or additions in the values ​​​​of the parameters of the boilers, resulting from the improvement of the design by the manufacturer.

Advantages and disadvantages

It is customary to attribute to the advantages of Navien Deluxe boilers:

• The ability to provide hot water supply along with the organization of home heating.
• Environmental safety of equipment.
• Adaptability to Russian technological and climatic conditions.
• Simple and reliable control, the presence of a remote control.
• The presence of a self-diagnosis system through a group of sensors that monitor all systems and components of the unit.

The disadvantages of the units are:

• Dependence on the availability of electricity, gas and water.
• High noise level.
• The ability to use only standard components.

All the features of the Navien Deluxe boilers, in fact, are specific design features and can be fully compensated for by proper operation and maintenance.

Device

The Navien gas double-circuit boiler heats the coolant and circulates it in the system.

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

To obtain the desired temperature, a certain amount of the cooled return is mixed, after which the coolant is sent to the system.

The combustion mode is regulated by the feed fresh air performed by the fan.

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

Where is used

Gas double-circuit boilers Navien Deluxe are designed for heating and supplying hot water in private homes.

The power of the boiler corresponds to the area served, which makes it easier to choose the right device.

For heating industrial or public buildings, the use of the Navien Deluxe series is not recommended, since the specific capabilities of the equipment in such conditions will not be fully disclosed.

Often, such equipment is installed in apartments, if their size allows you to install equipment of similar power.

What's Included

The package of boilers Navien includes:

• Primary and secondary heat exchangers.
• Expansion tank for 8 liters.
• Gas heater closed or open type.
• Three-way valve with electric motor.
• Fan for organizing turbocharging.
• Circulation pump.
• Sensor system connected to the control board.
• Built-in voltage regulator.
• Remote control.
• Body with external connections.

Depending on the model and series, some additional components may be present. Constant development and improvement of the design contributes to the complication of old and the emergence of new elements.

User manual

The operation of Navien boilers takes place automatically and practically does not need human participation.

The only thing required from the owner is installation comfortable temperature OV. If liquefied gas is used as fuel, it is necessary to monitor the timely replacement of cylinders.

The ability to operate for a long time without specialized service checks is a feature of Navien equipment, which is convenient for users and relieves them of concern about the condition of the unit.

If any malfunctions occur, the corresponding error code appears on the display, the water pressure is shown by a pressure gauge, which allows timely detection of system leakage.

The owner may be required to purchase and install a special filter or water softener, which will extend the life of most boiler components - the heat exchanger, pump or three-way valve. If the water supply is from your own well, the installation of a softener becomes a necessity.

Do-it-yourself device setup

To configure the boiler, set the debug mode. Then you should adjust the gas pressure limits - minimum and maximum.

From circulation pump air must be released by unscrewing the plug. This is done after a set of pressure during the circulation of RH.

The boiler operation is set using DIP switches.

• It is possible to turn on automatic de-airing with DIP switch No. 1, which will start circulation for 2 hours and de-air little by little automatically.
• Switching on switch #2 sets the system to maximum power, at which the maximum gas pressure can be adjusted.
• When switch No. 3 is turned on, the boiler is switched to forced operation mode when minimum power, at which the minimum gas pressure setting is performed.

All switching must be done with the power off.

Boiler adjustment should be entrusted to specialists from service center. Independent performance of work is possible only in case of urgent need and the absence of a guarantee contract.

Main malfunctions and their solutions

Faults that occur are shown on the display as a numerical code. Each of them corresponds to a certain error, i.e. a signal from a certain sensor about the failure of the corresponding node.

There may be additional codes, which should be carefully read in the user manual.

Instructions for use gas boiler Navien vividly describes the sequence of execution of commands to control this device, which is able to operate under such conditions when equipment from competitors simply stops.

In favor of this speaks how completely electronic system control, and the key principles applied to regulate the operation of the boiler. Navien, a product from a Korean manufacturer, is reliable, stable, able to cope with frankly emergency operating conditions.

Key product features

The boiler is distinguished by a low price. Nevertheless, the instructions for the Navien gas boiler are very detailed, the installation of any modes is thoroughly described. Thus, one can understand how seriously the manufacturer approached the presentation of the main aspects of management to the ordinary buyer. Users will have no problem setting up and using the device.

The system follows the same goal. electronic control, as well as adjusting other key parameters. To understand how versatile Navien equipment is, here is a short list of its abilities to work under non-standard conditions.

1. To protect and smooth out voltage surges in the power supply network, an adjustment circuit using a microprocessor chip is used. When parameters are changed, the electronics maintains a mode that allows all boiler components to function normally. This not only prolongs the life of the unit, but also eliminates some of the malfunctions of the Navien gas boiler, which could be caused by false alarms of the sensors. This feature of the electronics is very important, since the voltage of the power grid can fluctuate within 30% or more of the nominal value.
2. Possible blockages and malfunctions of Navien wall-mounted gas boilers caused by non-standard water pressure are minimized. The design is thought out so that it works confidently even when the indicator drops to 0.1 bar. This makes the unit ideal for installation on higher floors. apartment buildings, where periodically there is a drop in water pressure in the cold water circuit.
3. Malfunctions associated with non-standard gas pressure indicators are successfully neutralized by the Navien gas boiler device. Nozzles, protection systems, supply assurance are such that the unit works confidently even with a critical drop in supply pressure to 4 mbar. This is an extremely low figure that cannot be used by most modern systems with electronic control.
4. According to the instructions of the Navien gas wall-mounted boiler, freezing of the heating system will be prevented even if the gas supply is stopped. To prevent emergency operation when the coolant temperature drops below 5 degrees Celsius and it is impossible to ignite the burner, the built-in pump starts forced continuous circulation of water in the system, which prevents it from freezing.
5. Since all systems of this brand are equipped with a double heat exchanger for separate heating of hot water and heating medium, you can flexibly set the priority modes. It is even possible to set the conditions for preheating water for hot water supply. Electronics allows very convenient settings, and the instruction of the Navien double-circuit gas boiler will clearly show the user how to do this.

The equipment of this company provides for an extended control principle. The remote control from which the parameters and modes are configured is remote. It is also used as an external sensor-thermostat to measure and maintain the temperature in the room.

The engineering features of Navien products, which set high parameters for its quality, and also confirm the opinion of some experts about the unlimited life of boilers, include the following facts.

1. Corrosion-free separate stainless steel heat exchangers for high heat transfer.
2. Automatic pressure maintenance system in the heating system. If the pressure is exceeded, the water is drained, if the indicator is insufficient, it is taken from the cold water supply system, according to the instructions for the Navien gas boiler of a specific model. A pressure gauge is used to control the pressure.
3. The incoming water passes through the filter and is effectively cleaned.
4. Personal drain channels are provided to get rid of water in the coils if forced circulation is not possible.
5. The electronics controls the gas supply so precisely that the temperature of the water in the system can be set with an accuracy of 0.1°C.
6. AT summer period time, you can change the operating mode to meet only the need for hot water. This is easy to do both according to the instructions for Navien floor-standing gas boilers, and according to the documentation for other models.
7. To save fuel, there is a customizable "Away from Home" mode, when the boiler can maintain the minimum temperature in the room.

Key system weaknesses

With all the functionality, stuffed with electronics, convenience and ignoring difficult working conditions, gas boilers Navien is not without some shortcomings. Users often encounter cases where the device refuses to work because the electronics signal a critical error. This arises from different reasons, including those associated with the high sensitivity of the sensors. Let's take a look at two of the most common mistakes.
Smoke removal
If there are problems with the removal of combustion products, a fault code of 10 Navien gas boilers occurs. According to the user manual, there can be several reasons for such a signal:

• failure of the turbine (engine or due to a problem in the snail mechanism);
• incorrect connection of pressure sensor tubes;
• chimney blockage;
• large length of the pipe leading to the outside (the maximum length is indicated in the instructions);
• gusts of wind.

Most often, users experience the following picture:

• chimney of acceptable length;
• not clogged;
• the pressure sensor tubes are in order, since no intervention was made in the design.

Many are upset, thinking that the problem is in the operation of the turbine. However, oddly enough, most often the reason is strong wind on the street. According to the manufacturer, it is recommended to install boilers with the chimney exit on the leeward side of the building.

As a result of the fact that at different times of the year the wind blows differently, therefore, heating systems may refuse to work at the signal of the sensor, signaling a malfunction 10. One of the solution methods is to remake the chimney.

Since this cannot be done quickly, you can open the case of the device and disconnect the air supply pipe. The turbine will begin to take it out of the room, the boiler will start working. The solution is temporary, but it works.

Flame sensor failure

Malfunction error 03 of Navien gas boilers is caused by poor fuel quality. The mechanics of the problem is as follows:

• gas is supplied;
• the pressure in the line is sufficient so that the sensors do not raise an alarm;
• during ignition, there is no sufficient heating of the sensor electrode, since the distribution of temperature zones of the flame is disturbed.

The problem is solved exclusively by the selection method. The first thing to check is the cleanliness of the gas supply nozzles. If they are clean and fuel is supplied, the second step is to select the position of the sensor electrode. It must be in the hot phase of the flame for the signal to be correctly identified.

Such an error is rare where gas is supplied good quality, since the products of this company do an excellent job with any pressure indicators. But in regions with low quality gas treatment, a malfunction with code 03 is quite common. Sometimes it is necessary to change the position of the sensor electrode several times during one heating season.

In general, the manufacturer's heating systems are a fairly cheap, technologically advanced solution, ideal for coping with unusual working conditions. They can be extremely useful as they are very reliable and durable. All components are made by enterprises of Korea and Japan, the assembly is of high quality, the boilers meet all international standards.


Like any complex device, Navien boilers are not without problems. However, in most cases, the user does not encounter troubles when operating equipment from this manufacturer.

Navien gas boilers are compact in size, and also meet all European quality standards and safety and comfort requirements that such equipment must meet. Gas boilers are made from high quality material, they are distinguished by quality, efficiency and reliability. Read the instructions for connecting the Vaillant gas boiler.

The most important advantage of Navien gas heating equipment is adaptability to the difficult conditions of the Russian climate, to the low level of incoming pressure of the liquid coolant and gas, as well as to constant power surges in the electrical network.

Initially, Navien boilers are configured to work with natural gas, but there is the possibility of converting some boiler models to liquefied gas. To do this, you will need to purchase a manifold with nozzles.

Navien gas boilers are able to work even on low-quality fuel. They do not notice voltage drops, even if the surges reach a level of 30%.

A failure of a gas heater can only occur if the pressure level in the heating system, but this fact also becomes “+”, because if the coolant leaks, the boiler will stop working, which will protect the entire system from more serious problems.

All heating gas boilers are covered with anti-corrosion material.

Also, the cost of Navien gas boilers makes it affordable for almost the entire population of the country.

Boiler start

After completing all installation work and carrying out pressure testing, the first commissioning start-up of the boiler equipment is carried out. All work is carried out by the workers of the service center with the execution of the relevant documents, which in the future will preserve the manufacturer's warranty obligations.

When starting the Navien boiler, the instructions must be followed impeccably. Sequence of work:

1. The circuits are filled with water through the make-up unit of the unit, built into the structure, with a special faucet from below, next to the tap water inlet.
2. They monitor the pressure gauge, when the pressure rises to 2.0 atm, the valve is closed.
3. Remove air pockets. At the first start, they are performed in manual mode, and at subsequent ones - through automatic system. They start the process from the most remote battery, opening the Mayevsky faucet, alternately passing through all the points of the heating circuit.
4. After etching the air lock, the pressure in the circuit will drop, so re-feeding will be required.
5. Dump the air mixture from the circulation pump.
6. To turn on the unit, press the "Power" button.
7. The electric ignition will work and the unit will start, after which it is necessary to adjust the temperature regime.

Setting

"Navien" is programmed for winter (heating and DHW) and summer (DHW) modes of operation - with the icons "Snowflake" and "Sun". The temperature control in the network on the LCD panel is performed when the “radiator” icon is lit on it. In some versions, they start the "Heating mode", in others they scroll the knob. Flashing LED fixes set temperature water.

If the icon just lights up without pulsing, the actual temperature in the network is displayed. By selecting the icon, through "+" or "-", increase or decrease the temperature. After a couple of seconds, the LED stops flashing and shows the actual temperature. The heating temperature is regulated from 40.0 C to 80.0 C. If it is set incorrectly, an error code will be displayed.

Note! Adjustment DHW temperature carried out in a similar way, only on the remote control pictograms with a crane, the range is from +30 to +60 C.

The main advice of experts concerns safe operation boiler:

1. The room where the unit is located must be well ventilated.
2. The unit must have a separate independent connection to the mains.
3. The boiler must operate in a complete assembly and a protective case.
4. It is forbidden for the user to repair gas equipment boiler.
5. The boiler must be subjected to an annual inspection by Gorgaz representatives.
6. The owner of the boiler must periodically check the joints of the boiler and the gas pipeline for tightness with a soapy solution.

Additional Information. In the event of leaks, immediately close the gas valve, ventilate the room and call the emergency gas service.
