How to set up a Navien gas boiler - operating instructions. Navien wall-mounted boiler instructions. Gas boilers "Navien Ace" - operating instructions and advantages of the model Operating instructions for the navien boiler

Instructions for use gas boiler Navien colorfully describes the sequence of commands to control this device, which is capable of operating under conditions when competitors’ equipment simply stops.

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

Key Product Features

The boiler is distinguished by its 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 communicating the main aspects of control to the average buyer. Users will have no problems setting up and using the device.

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

1. To protect and smooth out voltage surges in the power supply network, a regulation circuit using a microprocessor chip is used. When changing parameters, the electronics maintains a mode that allows all components of the boiler to function normally. This not only extends the service life of the unit, but also eliminates some malfunctions of the Navien gas boiler, which could be caused by false alarms of the sensors. This feature electronics is very important, since the power grid voltage can fluctuate within 30% or more of the nominal voltage.
2. Possible blockages and malfunctions of Navien wall-mounted gas boilers caused by non-standard water pressure are minimized. The design is thought out in such a way that it works reliably even when the indicator drops to 0.1 bar. This makes the device ideal for installation on upper floors apartment buildings, where there is a periodic drop in water pressure in the cold water supply circuit.
3. Malfunctions associated with non-standard gas pressure indicators are successfully neutralized by the Navien gas boiler device. The nozzles, protection systems, and supply provision are such that the unit operates confidently even with a critical drop in supply pressure to 4 mbar. This is an extremely low indicator that cannot be used by most modern systems with electronic control.
4. According to the instructions for the Navien gas wall-mounted boiler, freezing of the heating system will be prevented even if the gas supply is stopped. To prevent emergency mode when the coolant temperature drops below 5 degrees Celsius and the burner cannot be ignited, the built-in pump begins 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 hot water and heating coolant, priority modes can be flexibly configured. It is even possible to set the conditions for preheating water for hot water supply. The electronics allow for very convenient settings, and the instructions for the Navien double-circuit gas boiler will clearly show the user how to do this.

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

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

1. Separate heat exchangers from of stainless steel, not subject to corrosion, providing high heat transfer.
2. System automatic maintenance pressure in the heating system. If the pressure is exceeded, the water is drained, and if the pressure 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 pressure.
3. The incoming water passes through the filter and is effectively purified.
4. Personal drain channels are provided to get rid of water in the coils if forced circulation is not possible.
5. Electronics control the gas supply so precisely that the water temperature in the system can be set with an accuracy of 0.1°C.
6. In summer, you can change the operating mode to provide only the need for hot water. This is easy to do both according to the instructions for floor-standing gas boilers Navien, and according to the documentation for other models.
7. To save fuel, there is a customizable “Away” mode, when the boiler can maintain a minimum temperature in the room.

Key system shortcomings

With all the functionality, crammed with electronics, convenience and ignoring difficult working conditions, Navien gas boilers are not without some drawbacks. Users often encounter cases where the device refuses to work because the electronics indicate critical error. This occurs by various reasons, including those associated with the high sensitivity of sensors. Let's look at two of the most frequently repeated mistakes.
Smoke removal
If there are problems with the removal of combustion products, fault code 10 of Navien gas boilers appears. According to the user manual, there may be several reasons for this signal:

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

Most often, users experience the following picture:

• chimney of permissible length;
• not clogged;
• The pressure sensor tubes are in order, since no intervention was made to the structure.

Many people get upset, thinking that there are problems with 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 exiting on the leeward side of the building.

As a result of the fact that in different time The wind blows differently every year, so heating systems may refuse to work based on a sensor signal, signaling a malfunction 10. One of the solution methods is to remake the chimney.

Since this cannot be done quickly, you can open the device case 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 are as follows:

• gas is supplied;
• the pressure in the line is sufficient so that the sensors do not raise an alarm;
• When igniting, the sensor electrode does not warm up sufficiently, since the distribution of the temperature zones of the flame is disrupted.

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 recognized.

This 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, fault 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 represent a fairly cheap, technologically equipped solution, ideal for coping with non-standard operating conditions. They can be extremely useful because they are very reliable and durable. All components are produced by enterprises in 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 any problems when using equipment from this manufacturer.

If we consider the turnover of heating devices on the domestic market, we can see that consumers give preference to European equipment. However, the Korean Navien mounted boiler, the price of which is lower than its Western counterparts, occupies the top position among other heating devices. This is due to the durability of the product and the availability of warranty service. Also read: “Gas boiler from Beretta - simple, reliable and functional”

What types of Navien wall-mounted boilers are there?

Made in Korea.

A company from Asia loudly declared itself and its products, so the choice of European brands was reduced. Products from a Korean company can compete with gas units from any European manufacturer. Therefore, user reviews about the Navien gas boiler are only positive.

One of the most popular and reliable is the double-circuit mounted boiler unit of the Ace line. Such devices may have an open or closed combustion chamber. The functional component of the device is durable, which is noted by users and specialists. At the same time, the price of the Navien mounted boiler is much lower than the equipment offered by European brands.

The line is represented by several devices:

• Navien Ace ATMO;
• Navien Ace-20k;
• Navien Ace TURBO.

The last model is worth considering first. This boiler is available in two variations - Korea and Coaxial. Wall-mounted equipment for the heating system has a rated power of 13-40 kW. Moreover, this indicator does not depend on the modification. The Navien gas boiler, according to reviews, is ideal for use in the climatic conditions of our country.

The equipment is characterized by its ability to operate in difficult operating conditions: pressure surges in the gas pipeline, and voltage surges in the power supply network. Even being for a long time not turned on, such a boiler will start without problems and perform its functions 100%.

The wall-mounted double-circuit boiler is characterized by the following:

• application for heating water and heating residential buildings;
• the equipment contains a steel heat exchanger coated with anti-corrosion, which significantly reduces the cost of the equipment in comparison with boilers equipped with copper heat exchangers;
• Navien Ace gas boiler (operating instructions included with each model) is easy to use;

Wall-mounted hardware has brains. This means that the unit ensures that the coolant does not freeze in the pipelines of the heating system. Automation works in two cases. The first is when the water temperature drops to 10 degrees. At this time the time is turned on. The second situation occurs when the coolant temperature is less than 6°C. In this case it turns on gas-burner, warming up the coolant to 21 degrees.

The Navien Ace TURBO double-circuit boiler and the 16k model will operate when the voltage in the power supply network is reduced to 30%. IN Navien instructions Ace 16k also states that the boiler will not turn off when the water pressure in the system is 0.1 bar.

Navien products have positive reviews. This is due to the long period of use and high efficiency of the unit. The equipment is characterized by high fuel and electricity savings. This is facilitated by the presence of turbocharging and an APS sensor, which monitors air pressure.

Characteristics of Navien Ace ATMO and Navien Ace 20k

The boiler is equipped with uninterruptible voltage.

The company's products include double-circuit boilers with and without turbocharging. The latter belong to the Ace ATMO line. They have the same functions as the turbocharged version. Korean gas boilers Navien Ace reviews are largely positive, which once again indicates the quality of the product.

This unit is equipped with the same chip that ensures uninterrupted operation during power surges as the above-described models. A distinctive feature of the device is the absence of turbocharging, which ensures silent operation.

Navien Ace 20k, like other units of the Korean brand, is fully adapted to climatic conditions Russia. The device operates reliably at low gas and water pressure, which makes it possible to use them in multi-storey buildings. residential buildings. This expands their scope of application. Organizing the removal of combustion products can be carried out in different ways:

• by installing a horizontal (conventional) chimney;
• at separate system smoke removal;
• by mounting in a vertical position.

It is important to note that some variations of equipment from Navien support remote control using a phone or tablet.

The instructions for using the Navien gas boiler colorfully describe the sequence of execution of commands to control this device, which is capable of operating under such conditions when equipment from competitors simply stops.

This is supported by both the fully electronic control system and the key principles used to regulate the operation of the boiler. Navien, a product from a Korean manufacturer, is reliable, stable, and able to cope with frankly emergency operating conditions.

Navien is a large South Korean corporation that produces universal, high-quality and reliable gas boilers. Navien devices are distinguished by trouble-free operation, practicality and functionality. These devices have an open or closed combustion chamber; their functional part is durable. At the same time, their cost is lower when compared with European analogues.

Navien presents a universal water heating system

Navien Ace gas boilers are not afraid of low pressure of gas and water, they are not afraid of voltage drops in the network. The operation of Navien gas boilers is characterized by a long service life and economical gas consumption. All Navien gas devices comply with the standards and regulations of the Russian Federation and have the appropriate certificates.

Frost protection system stability

If the room temperature drops, then automatic protection system is triggered from freezing. When the temperature of the heating water drops more than 10 degrees Celsius, it automatically starts circulation pump, resulting in constant circulation of coolant in the heating system. If the temperature of the heating water drops to 6 degrees Celsius, the burner is automatically turned on and the coolant warms up to 21 degrees Celsius.

Safety of operation during frequent power surges

According to the instructions, the voltage can fluctuate within ±30 percent due to the triggering of the Switched - Mode Power Supply (SMPS) protective chip on the microprocessor. Wherein boiler operation does not stop, which prolongs its service life and prevents breakdowns.

Operating conditions for heating and hot water:

• subject to low inlet pressure in the gas pipeline system, stable and safe operation of the Navien Ace gas boiler is possible at a gas pressure of four mbar (40 millimeters of water column);
• subject to low incoming water pressure in the water supply - stable operation of the Navien Ace gas boiler is possible provided that the incoming water pressure drops to 0.3 bar, which lets apply this gas device in houses where there is low water pressure in the water supply system, including where there are frequent pressure drops in the water supply system.

Rational design

Gas boilers Navien are different small in size and light weight, they are convenient to transport, they are easy to install and it is possible rational use room area. For ease of installation, the connecting tubes are located on both sides of the device, which greatly simplifies the piping and installation of the Navien Ace gas boiler.

Fuel preheating (KR series)

At low temperatures, the viscosity of the fuel increases, resulting in a waxing effect, which significantly impairs the flammability of diesel fuel and the operation of the Navien gas boiler becomes unstable. This feature of operation is relevant for regions with harsh climates, therefore arctic and winter diesel fuels were created for these conditions.

Gas devices Navien work on any diesel fuel Russian production However, the cost of winter or arctic diesel fuel is much higher than that of summer diesel fuel, and the use of summer fuel is impossible at low temperatures without preheating it.

The heating element, which is built into the burner of the Navien gas unit, preheats it before supplying fuel to the nozzle, resulting in high-quality fuel atomization and uninterrupted ignition. Due to preheating, Navien Ace gas boilers have possibility of using inexpensive summer diesel fuel, which leads to significant savings.

The Navien boiler is high-quality South Korean heating equipment. The company produces modern gas boilers. These products quickly gained the trust of consumers and became a regular participant in the domestic market, significantly expanding the ability of buyers to choose the ideal boiler for themselves.

Photo of the Navien boiler

Wall-mounted and floor-standing boilers from Navien have a number of features that set them apart from their competitors.

1. System for working during power surges. Navien gas boiler models are distinguished by the presence of technical components that allow the equipment to operate even with differences in the power supply reaching 30 percent. This is a guarantee that your wall-mounted boilers will not require repairs if problems arise with the electricity in your home. And such situations are not uncommon for us.
2. Ability to operate at low water system pressure. Problems with pressure in the water supply are less common, but even if they occur, the boiler will function normally and provide heat to the entire house.
3. Not one heat exchanger, but two. All wall-mounted models of Navien boilers have not one heat exchanger, but a pair. Each heat exchanger is made of stainless steel, which is reliable, efficient and corrosion resistant. This design with a pair of heat exchangers increases the boiler’s resistance to water contamination, scale, and ensures affordable repair. The price of the Navien boilers themselves is quite attractive - from 30 thousand rubles. There are also more expensive, efficient models that can provide heat to large rooms.
4. Turbocharging Each floor-standing and wall-mounted boiler from the South Korean company Navien is equipped with a turbocharger - an air supply system. This increases the efficiency of the boiler device. The air supply pressure is regulated automatically. As a result, better heating of the house is provided with less fuel.

Advantages

We talked to you about the design features of Navien boilers. That's four objective reasons pay close attention to such models as the Navien Ace and Deluxe, Prime boilers.

If we put Navien boilers on a par with competitors represented on the domestic market in approximately the same price category, the South Korean manufacturer will demonstrate whole line obvious advantages:

• High level of quality and reliability of automation. Errors for such boilers are rare and can only be caused by system failures or improper control by the user. But if errors occur on Deluxe, Prime or Ace models, fixing them is quite simple. Most of the work is done by automation. Errors are easy to read, the reasons for their occurrence are determined according to the manufacturer’s instructions;
• Availability of SMPT protection chips. With their help, gas boiler equipment works perfectly under conditions of an unstable electrical network. You all know how often problems arise with the electrical network in our homes. Many boilers are not able to cope with such fluctuations; they constantly produce errors and fail. With Navien boilers, such situations are minimized;
• Adaptability of Navien boilers to operating conditions in domestic realities. We are talking about unstable pressure in the gas pipeline and problems with water pressure in the water supply. Boiler company Navien models Prime, Deluxe or Ace cope perfectly with such conditions, when gas pressure drops to 4 mbar and water pressure to 0.1 mbar;
• Real Korean assembly. Unlike many products that have European or other designations on their bodies, Navien boilers are actually assembled in Korea, and not somewhere in China in order to reduce the cost of assembly. It is no secret that many foreign companies are setting up production in the Middle Kingdom. And they pass off the equipment as European, for example;
• Remote controls. Navien boilers are equipped with special convenient remote controls, with which the user can remotely change the operating modes of their boiler equipment.

Range

The assortment of the South Korean company Navien is constantly expanding, which allows customers to purchase gas boilers that are optimally suited in all respects.

Therefore, tell us about all the representatives model range impossible. Instead, we will look at Navien equipment, which can be divided into three broad categories.

1. Wall models. Wall-mounted boilers have a double heat exchanger and are labeled as Ace, Deluxe. Deluxe are dual-circuit models that have a wide power range from 13 to 40 kW. All Deluxe series boilers are turbocharged. Turbocharged Deluxe equipment can have a coaxial or separate chimney. In addition to Deluxe, the Ace series of wall models is in great demand. The Ace series is divided into Turbo and Atmo. The difference between them is that Turbos are fully adapted for operation in conditions of non-steel gas and electricity supply to the boiler. Additional benefit ACE Turbo is anti-freeze protection and turbocharging of the burner. If we talk about Atmo, then this is a classic gas boiler that perfectly provides heating for a private home. Atmo has everything strengths Turbo, except for burner turbocharging.
2. Floor-standing boilers from Navien. If wall-mounted models do not suit you for one reason or another, floor-standing models have earned excellent reviews. They are used for heating and hot water supply of private houses. The distinctive features of floor-standing models of Navien boilers include their compact size, ease of operation and convenient installation. Each boiler is supplied with instructions, according to which even a novice in such matters can carry out the installation. Wall-mounted models are somewhat easier to install, although there are no problems with them. A double heat exchanger significantly increases the efficiency of heat generation in a gas boiler.
3. Condensation. Deluxe, Ace and other models of the Navien company recently received a serious competitor in the form of South Korean condensing boilers. They are marked NCN. Their distinctive feature is increased power, the range of which is 19.6-37.9 kW. These boilers use fuel efficiently, using less fuel but providing higher quality heating. The efficiency of Navien condensing-type boilers reaches 108 percent. This was made possible by using the heat that is released when steam condenses. This way consumers save money on gas bills, but heat more efficiently own house. The heat exchanger here is slightly different. Its design is unique and is distinguished by the presence of a system for preliminary creation of a combustible mixture. The burners are necessarily modulating, the range of operation of which is amazing.

By choosing boilers from the Navien company from the Deluxe, Ace or other ranges, you are buying quality and reliability. This is one of the few cases where the manufacturer does not demand more just for the brand. The high level of Navien boilers is beyond doubt.

Heating installations with Korean “roots”, Navien, are often used both in private country houses, and in apartments.

What is the reason for such popularity? design features has the equipment and what difficulties a consumer may encounter when purchasing a Navien gas boiler.

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

Navien produces devices different power, designed to provide heating for gasified houses. However technical features models allow you to switch them to an autonomous gas supply, that is, connect them to cylinders.

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

There are boilers:

• wall and floor;
• single-circuit and with hot water supply;
• with atmospheric and closed camera combustion;

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

Initially, Navien boilers are configured to work with natural gas, but it is possible to convert some boiler models to liquefied gas. To do this, you will need to purchase a manifold with injectors.

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

Failure of a gas heating appliance can only occur if the pressure level in the heating system, but this fact also becomes a “+”, because if the coolant liquid 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 accessible to almost the entire population of the country.
