Gas boiler Navien price.

The Korean brand "Navien" rapidly broke into the Russian market of heating equipment. Against the backdrop of expensive and constantly rising in price analogues of imported production, the Navien gas boiler has taken the best position in the price niche for the average wallet. Navien's specialization in the production of reliable and energy-efficient gas boilers allows us to offer the consumer high-quality and functional equipment, sometimes half the price of famous brands.

It is well known in Russia that South Korea is famous for talented engineers and developers who implement innovative technologies in our daily lives, and the Navien gas boiler is another confirmation of this. The price for a Navien deluxe 24k gas boiler on store shelves starts at 30 thousand rubles.

Gas boiler Navien design features:

So, we present to your attention the Navien wall-mounted gas boiler, in which a two-circuit system with a closed combustion chamber fits. These modifications are widely represented on the Russian market. Consider their differences from each other, device and technical characteristics. and also let's talk about what advantages Korean manufacturers promise us and try to find the shortcomings that Navien's engineers are silent about.

The first thing you should pay attention to is all the Navien gas boilers we are considering, fully adapted to Russian operating conditions. As we have already mentioned, a double-circuit system, in addition to its direct purpose - to serve as a source of heat in heating systems, allows you to provide the homeowner with hot water in sufficient quantities.

Structurally, the Navien gas boiler can be divided into two types: the first is turbocharged, that is, they are made with forced draft using a fan. The second is atmospheric with natural draft and removal of combustion products. Each model, and there are only four of them, is represented by a wide variety of capacities - up to seven modifications. This range allows you to find a suitable version of the boiler with the most suitable power. The most powerful wall-mounted gas boiler Navien from the manufacturer KyungDong Navien is able to heat a living area up to 400 m2.

Turbocharged wall-mounted boilers with closed combustion chamber represented by three models: Navien Smart Current, Prime Coaxial and Deluxe. The hallmark of the Korean enterprise in the domestic market is the device H Avien deluxe 24k. Instructions for the device in Russian, for which special thanks to the Korean comrades.

Technical characteristics of boilers Navien Smart Current Coaxial, Navien Prime Coaxial

Navien deluxe 24k specifications

If you are planning to equip a coaxial type chimney, then you should buy a Navien Delux coaxial gas boiler, respectively, which is equipped with a coaxial chimney. This design is a device when one pipe is inside another pipe. A pipe with a smaller diameter, which is located inside, ensures the removal of combustion products, the outer pipe serves to supply air necessary to maintain combustion in a closed chamber.

The diameter of the coaxial pipe for this boiler is 60 x 100 mm. In addition, the Deluxe coaxial boiler allows installation with a so-called separate chimney if the situation requires it. When installing a separate system, the exhaust of combustion products is attached to the central outlet. The pipe providing the air supply is attached to the right or left branch pipe, depending on the situation at the place where the chimney is arranged.

Navien deluxe 24k customer reviews are generally positive, and given the 24-month warranty and the low price per unit, the purchase is becoming more and more attractive.

Wall-mounted gas boiler from Navien with open combustion chamber represented by only one double-circuit boiler without turbocharging model: Navien Ace atmo.

Navien Ace atmo manual

Each such boiler has an “A” index in its name, which indicates that the device is atmospheric. And as we mentioned earlier, the removal of combustion products is carried out using natural draft through the chimney. The room where the boiler is installed should be more thoroughly ventilated.

In case of insufficient or low ventilation of the heated room, the combustion process may be disturbed. Firstly, the service life of the boiler is reduced, and secondly, with insufficient ventilation, carbon monoxide can accumulate in the room, which causes poisoning of the household.

Boiler Navien Device and main elements

The double-circuit gas boiler Navien in its arsenal contains all the modern components that are included in the standard set of the device. You can see them in more detail in the figure below:

The heat exchanger is made of stainless steel. Compared to a traditional copper heat exchanger, this solution increased the corrosion resistance by 6 times, which led to an increase in the service life of the gas boiler. Despite the advantages of stainless steel in corrosion resistance, the thermal conductivity is still inferior compared to copper heat exchangers. The company's engineers have developed a special simulated turbocharging system.

This system works with a change in fan speed. The command to change the speed comes on a signal from the air pressure sensor. Changing the fan speed provides the required air to the full volume of the closed combustion chamber, so the engineers have increased the efficiency of the boiler without increasing the gas consumption. And the efficiency of a stainless steel heat exchanger is equal to the efficiency of boilers with a built-in copper heat exchanger.

The company's engineers have taken care of the technology that constantly adapts the operation of the boiler to home conditions. This is facilitated by a remote control panel. The company's engineers provided the remote control with a temperature sensor, which is already included in the total cost of the equipment.

Remote boiler control panel with built-in room temperature sensor

It is worth noting here that most competitors sell such an option as a temperature sensor separately. For better adaptation of the boiler, it is recommended to mount the remote control panel at a height of one and a half meters from the floor. A place must be chosen where there are no drafts and where direct sunlight does not fall.

The correct air temperature readings to which the sensor reacts and transmits to the electronic control board depend on the selected installation location of the remote control. The remote control itself is mounted with screws, and it is connected to the boiler with just two wires. On the remote control unit you can see all the data on the operation of the boiler, as well as possible malfunctions or errors. Temperature indicators of air, coolant, and water, as well as the exact time, all this is displayed on the display.

Before turning on the Navien gas boiler, it is worth checking the reliability of the electrical wiring, among other things, it is necessary to ground the boiler, which will serve as protection against possible electric shock.

The main elements of the lower part of the Navien boiler

  1. heating water filter
  2. drain plug
  3. safety valve
  4. make-up tap outlet
  5. heating water supply (inlet) 3/4 inch
  6. heating water return (outlet) 3/4 inch
  7. domestic hot water 1/2 inch
  8. cold domestic water supply 1/2 inch
  9. gas supply 3/4 in.

Recommendations for installing the boiler are quite standard: The easiest way to make a protective screen is from a sheet of metal. Stainless steel sheet is the best for this purpose. The sheet should be installed between the boiler and the wall. The manufacturer prudently includes a mounting plate in the delivery set.

Boiler Navien errors and malfunctions

So let's summarize the review of the Navien gas boiler

Advantages

  • Any consumer can afford to buy a Navien gas boiler. The price-quality ratio clearly speaks in favor of the Navien Deluxe 24k boiler from a Korean manufacturer.
  • An unexpected decision to install a heat exchanger made of a material such as stainless steel makes the boiler more durable.
  • A remote control unit with a built-in temperature sensor adapts the operation of the boiler to constantly changing conditions, which makes staying indoors more comfortable.
  • the presence of a protective chip against a power surge
  • wide range of models and colors
  • 100% supply of original inexpensive spare parts

Disadvantages:

According to some reviews, the noise level is slightly too high for the declared parameters. Perhaps, as one of the solutions - installing the boiler in a specially designated place.
The reverse side of Korean quality - original spare parts are suitable.
Some consumers are skeptical of Asian companies, preferring "European" quality.

Taking into account the technical characteristics of the Navien Deluxe 24k and the ratio of price and quality, it is probably possible to pay special attention to Korean-made boilers when choosing a gas boiler. It is really reliable and up-to-date for a high-grade .

It is well known that South Korea is a high-tech country that supplies the widest range of modern household appliances around the world, including the states of the former USSR. And more recently, this list has been replenished with heating equipment running on natural gas. We present to your attention a product of a well-known Asian brand - the Korean gas boiler Navien, which has been sold in the Russian Federation for several years and managed to gain a certain positive reputation.

Model range of wall-mounted boilers Navien

It should be noted that the first reviews of Russian users about this product were not too enthusiastic. There are objective reasons for this, one of them is frequent leakage of connections, which was eliminated by replacing an expensive set of gaskets. Another nuisance was that the Navien Ace boiler offered at that time pestered users with a late start-up of the burner, when the coolant in the batteries had time to cool down pretty much.

The company has clearly worked on the bugs, as there are much fewer negative reviews, and the number of supporters of the South Korean manufacturer has grown significantly, primarily due to the reasonable price of decent quality products. At the moment, under the Navien brand, 3 types of suspended gas heat generators are offered:

  • atmospheric;
  • turbocharged;
  • condensation.

The atmospheric series of units with an open combustion chamber is represented by the Navien Atmo brand boiler, which replaced the not-so-successful Ace model. The heat generator is adapted to difficult operating conditions, which is reflected in the low operating pressure of gas (from 8 mbar) and water in the centralized network (from 0.6 bar). The series includes 4 boilers with a capacity of 13, 16, 20 and 24 kW, equipped with a copper heat exchanger for heating and a separate stainless steel one for heating water for domestic hot water needs.

Note. Only double-circuit boilers Navien are supplied to Russia and the CIS countries, both in wall and floor versions. In addition, all Navien units are equipped with modulating burners, an integrated expansion tank and circulation pump, as well as an electric ignition system.

The unit is controlled automatically by means of a remote control. In addition to the minimum set of protective automation, the boiler has an additional system that prevents the coolant from freezing. At the same time, the manufacturer prohibits filling the heating system with antifreeze, the heat generator is not suitable for this. The main specifications of the Atmo series are as follows:

  • water heating temperature in the heating system - 80 ° C, operating pressure up to 3 bar;
  • in the DHW circuit, water is heated up to 60 ° C;
  • gas pressure - from 8 to 18 mbar;
  • Efficiency - 86%;
  • water pressure in the network - from 0.6 to 8 bar.

Turbo models

The line of wall-mounted boilers Navien with a closed combustion chamber includes as many as 3 series of units:

  • Deluxe - 7 heat generators with power from 13 to 40 kW.
  • Prime - 6 products with a capacity of 13-35 kW;
  • Smart TOK - 6 heaters from 13 to 35 kW.

For reference. The hanging boiler Navien Ace Turbo is a thing of the past, and its place is taken by the Deluxe and Prime brand units.

The difference between supercharged heaters is that the air supply to the closed combustion chamber is carried out forcibly by means of a fan, its performance is controlled by the controller. Air entering through the coaxial chimney from the street enters the sealed housing, where it is captured by the fan. Thanks to forced injection, all these models have an increased efficiency of 92%.

This is where the fundamental differences between turbocharged units and atmospheric ones end. Their equipment is just as rich: the Navien Deluxe wall-mounted gas boiler is equipped with an expansion tank, a pump and an additional heat exchanger for hot water. In addition, the device withstands voltage drops of ± 30 V from the nominal value, and also automatically turns on heating when the coolant temperature drops below 6 ° C, bringing it to 21 ° C.

The Prime series, as well as the Deluxe Coaxial boiler, is equipped with a closed combustion chamber and other functional elements listed above. The difference is in the additional weather-compensated automation module that controls heating depending on environmental conditions. The SmartTOK series is even more automated, these boilers can be controlled remotely via the Internet. To do this, you need to have a smartphone and download a special application to it.

Condensing heat generators

Unlike the modifications discussed earlier, the Navien NCN and NCB boiler heat exchanger is made of stainless steel and is designed to take away not only direct, but also latent heat released during gas combustion. Hence the high efficiency of the units, the manufacturer declares it at the level of 98%. The complete set of products is the same as for turbocharged boilers, only the controller has an extended number of functions, for example, programming the climate in the house for a week in advance. The NCN series consists of 4 products with a heat output range of 21-40 kW, NCB - of 4 heaters from 24 to 40 kW.

As for the technical characteristics, in condensing heat generators, hot water for the heating system can be heated up to 90 ° C, and for hot water - up to 65 ° C. The maximum water pressure in the centralized network has also been increased, the boiler can withstand up to 10 bar. The air supply is forced, it can be carried out both with the help of a coaxial and a separate chimney. That is, the homeowner can choose whether to take air from the street or from the boiler room.

Floor standing boilers Navien

This type of heat generators is positioned by the manufacturer as universal, they can operate on diesel fuel and natural gas. In fact, Korean floor-mounted gas boilers are just as well stuffed with automation as their wall-mounted counterparts. The difference is in the installation method and the maximum power of some models. The line includes 4 series:

  • LST, 8 products from 13 to 60 kW.
  • LFA, 6 heaters from 13 to 40 kW.
  • GA, 7 boilers with a capacity of 11-35 kW.
  • GST, 5 units from 35 to 60 kW of power.

In terms of technical characteristics, they are also close to suspended ones, the maximum operating temperature is 80 ° C, pressure - 3 bar. Efficiency index - 91%, air supply method - forced injection.

How to turn on the Navien boiler

A feature of South Korean heaters is the presence of remote control panels, which are supplied with all products. The attached instruction manual states that the boiler can be turned on either using the remote control or using the buttons on the front panel of the unit. This operation is simple: you need to press the "power" button, its location is shown in the diagram:

After starting, the boiler will automatically start working in the mode that was last set on the remote control. To change the settings, you need to take the manual and use it to correctly set all modes. Before starting a new heat generator, you need to install it, connect it to all engineering networks and fill the heating system with water, focusing on the boiler pressure gauge. The location and purpose of the nozzles is shown in the figure:

Navien boiler errors

During start-up and operation, various error codes may appear on the display of the device, indicating a malfunction of the boiler or malfunctions in the heating system. The decoding of all codes is given at the end of the instruction manual, but not always in an understandable language. We will give an explanation of frequently occurring errors.

If the boiler stops and error 02 appears on the display, this indicates that the flow sensor has been triggered in the heating system. The reasons may be:

  • the circulation pump is out of order or disconnected from the power supply;
  • there is air in the system;
  • the filter at the coolant inlet to the boiler is clogged;
  • there was a leak, and make-up does not work;
  • the sensor itself or its electrical circuit is faulty.

When the unit does not start, and error 03 is on the screen, the cause is in the flame sensor. It works if it “does not see” the fire, which means that there may be problems with the gas supply or its pressure is too low. Also, the cause may be contamination of the ignition electrodes or the surface of the sensor. The failure of the sensor itself or the absence of a signal due to an open circuit cannot be ruled out.

Conclusion

South Korean Navien boilers using natural gas have become familiar to many users, although they have appeared relatively recently. In general, their work is characterized positively, but there are significant shortcomings. For example, a ban on the use of antifreeze in the system, which is very important in harsh winter conditions.

Popular Models

The time has come to consider the most popular models of Navien gas boilers, in demand among domestic consumers. It is they who deserve the highest ratings from users, providing them with warmth.

The double-circuit gas boiler Navien ATMO 24AN is made according to the traditional convection scheme and is equipped with an open combustion chamber. With a power of 24 kW, it can warm up to 240 square meters. m. of living space, spending up to 2.47 cubic meters. m / h (this is the maximum figure). The DHW capacity reaches 13.7 l/min. The primary heat exchanger is made of copper, the secondary heat exchanger is made of durable steel. If necessary, the device can be reconfigured to work with liquefied gas.

For more convenient control, remote controls with built-in thermostats are connected to the unit (such a remote control is supplied). Inside them, all the necessary piping is provided - these are expansion tanks and circulation pumps. The estimated cost of equipment varies between 23-26 thousand rubles.


Before us is a mounted boiler Navien, created on the basis of a burner with a closed combustion chamber. Unlike the previous model, a clear minus catches the eye - this is a steel primary heat exchanger. If we analyze the reviews of experts, we can find out that copper heat exchangers are the most stable and easy to repair, but equipment with them is more expensive. The power of the presented unit is 24 kW, the capacity of the DHW circuit is up to 13.8 l / min. It is electronically controlled with a diagnostic system and a room thermostat. The efficiency of the device is 90.5%, the cost is 24-26 thousand rubles.

It is endowed with a closed combustion chamber, an electronic control system, a remote control, a control option via the Internet, a self-diagnosis system, a programmer for operating modes, built-in piping and an outdoor temperature sensor. In other words, this is the most stuffed device from the Korean Navien. Thermal power is adjustable in the range from 8 to 24 kW, the performance of the DHW circuit is up to 13.8 l / min. The efficiency is 91%, the maximum gas consumption reaches 2.79 cubic meters. m/hour. It is possible to operate the device on liquefied gas.

Owner reviews

Before you buy a good gas boiler from Navien, it would not hurt to study the reviews of already established users. They will point out weaknesses and help to give a preliminary assessment of certain models.

Gas boiler Navien DELUXE 24K

Alexei, 29 years

The boiler was chosen for a long time - before we settled on Navien, we re-read a bunch of reviews and reviews. After numerous consultations with sellers and heating specialists, we settled on this model. All the same specialists were engaged in the installation, he did not dare to do anything. The first winter was successful, there were no breakdowns during operation. Very convenient control - the remote control was placed next to the sofa in the living room. You set the temperature, and the unit standing in the kitchen independently maintains the required mode.

Advantages:

  • Compactness - compared with some other devices, in particular, from Proterm. As a result, the Navien Deluxe boiler turned out to be thinner;
  • Low noise level - a couple of times in winter we visited neighbors and heard how their boiler from Baksi was working, rattling and howling with a fan;
  • The quick achievement of the set temperature is important after our long business trips, when you enter the house and want to quickly feel comfortable.

Disadvantages:

  • The absence of controls on the gas boiler itself, as is implemented in other heating units - in this, specialists from Navien made a mistake;
  • Sometimes there is not enough DHW performance - two open taps lead to a decrease in temperature.

An excellent device with minor imperfections (like everyone else, probably).

Gas boiler Navien DELUXE COAXIAL 24K,

Stepan, 37 years

I never trusted modern double-circuit gas boilers, and my instinct was fully justified. Friends persuaded me to take a model from Navien, they say, it works perfectly and is inexpensive. I was just finishing the construction of the house and urgently needed heating. I took a double-circuit, and after a year and a half I began to count the number of breakdowns. Not the most reliable device, so I can not advise anyone to buy it. If we are already doing heating, then we need to install an ordinary floor single-circuit with an indirect heating water heater - it will turn out inexpensively and quite reliably.

Advantages:

  • It maintains the temperature of hot water well - perhaps this is the only truly positive feature of this gas boiler from Navien;
  • No need to buy a harness - everything is already provided inside;
  • Self-diagnosis can show errors and failures.

Disadvantages:

  • The heat exchanger was probably made of foil, since it was the first to fail. They called the master, he shook his head and said that stainless steel is nonsense, that it was necessary to take a boiler with a copper heat exchanger;
  • One of the buttons on the remote control quickly failed;
  • The gas boiler from Navien often shows errors that are not actually there - probably the electronics are buggy.

Gas boiler Navien GST 35KN

Olet, 57 years old

For my country house, I purchased a powerful 35 kW floor-mounted double-circuit boiler. This choice was quite obvious - I trust full-fledged floor units more than densely arranged wall modifications. I was not mistaken in my choice - the gas boiler pleased me with trouble-free operation, the Koreans did a good job. And the performance of hot water supply here is impressive, up to 22.1 l / min - not a single wall-mounted sample can boast of such a characteristic. The unit is located in the basement, from which a control panel with a room thermostat rises to the first floor.

Advantages:

  • It is convenient to program the operating modes for the week ahead. Since I am in the city on weekdays, the device operates in anti-freeze mode, saving money in my wallet. By Friday evening, he begins to fill the house with warmth, so my family and friends come to an already warm home;
  • Nothing prevents you from simultaneously opening hot water taps in the shower and above the kitchen sink - there is enough performance for all points of water intake;
  • It can run on liquefied gas, it helped out a lot in the first year, then a gas pipeline appeared in the village.

Disadvantages:

  • For the first year, the Navien gas boiler stood in a small boiler room on the ground floor, but then it had to be moved to the basement - it makes a noticeable noise;
  • Frequent switching on and off of the burner - reacts literally to the smallest temperature changes;
  • It took almost a week to start the boiler and set it up - the specialists said that the logic of this device is not the most understandable.

Despite the flaws at the very beginning, further use goes without problems.

Gas boiler Navien SMART TOK 24K

Arkady, 61 years old

The time has come to make a major overhaul in the house, at the same time we decided to modernize the heating system. They threw out all the old pipes, installed modern bimetallic batteries, and at the same time changed the gas boiler by buying a double-circuit Navien with remote control. I was very pleased with the ability to control heating at a distance - I have a program with regulators on my smartphone, it works wherever there is Internet access. The thickness of the case is only 29 cm, so it does not stick out against the background of kitchen cabinets. Works faithfully and flawlessly.

Advantages:

  • In my opinion, this is the most thoughtful gas boiler - specialists from the Korean company Navien did a good job to give consumers an excellent heating unit with advanced remote control;
  • It is possible to control the climate in the house depending on the outside temperature. Programming is also provided, but I haven’t had a chance to use it yet (maybe we’ll try it on our next vacation);
  • No need to buy a pump and a tank - everything is already inside, without taking up space.

Disadvantages:

  • In the very first thunderstorm, the electronics burned out - as it turned out, in gas boilers (of any manufacturer, and not just from Navien), this is the most flimsy place. I had to put additional protection;
  • It took a long time to deal with the intricacies of control - in an effort to make the device very flexible in settings, the developers endowed it with a huge number of various adjustments (often not very necessary and not the most understandable);
  • You can’t repair it yourself - this is not a technique that you can handle with your own hands.

The gas boiler from Navien pleased with its automation, and you can not pay much attention to the shortcomings. The main thing is to protect the electronics from electrical overloads.

Autonomous heating and hot water supply turn a 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 successful options that combine affordable cost and high quality.

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

The company specializes in the production and design of heating equipment operating on various types of 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 the dwelling with hot water (DHW).

Korean developments were carried out taking into account Russian conditions and are specialized to work with unstable parameters in all areas - 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 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.

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 the technical characteristics of Navien Deluxe boilers:

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 supply of fresh air, which is 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

Navien Deluxe gas double-circuit boilers 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 that is required from the owner is to set a comfortable temperature for the heating. 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.

It is necessary to release air from the circulation pump 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.
  • Turning switch #2 on switches 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 at minimum power, at which the minimum gas pressure is adjusted.

All switching must be done with the power off.

Boiler adjustment should be entrusted to specialists from the 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.
