Navien gas boiler instruction. Complete set and principle of operation of the Navien Ace boiler
Gas wall-mounted boiler NAVIEN
When the consumer is faced with a choice gas boiler for heating, it is necessary to take into account a large number of criteria that ensure its efficient and economical operation. In this regard, domestic and foreign units should be divided. Unfortunately, not all "foreigners" can withstand the difficult Russian operating conditions - poor quality of the coolant, pressure drops in gas and water, periodic power outages. True, many foreign analogues today have already been adapted to Russian conditions. For example, the well-known South Korean model line "Navien Ace" with instructions stating that these boilers can be used in Russia.
The Navien Ace brand is a wall-mounted version of a double-circuit boiler. This model refers to the equipment "Navien" with an open combustion chamber and natural output of combustion products. What is included in the design of the boiler?
Boiler equipment
The design of the unit includes:
- Two heat exchangers made of stainless steel, which guarantees their long and reliable operation.
- Remote display of the control unit, which is fully Russified. For the Russian consumer, this is a very important condition.
- Built-in circulation pump.
- Expansion tank.
- Safety valve.
- Automatic air vent.
- Bypass valve, which is also configured in automatic mode.
- Traction sensor.
- Electric current stabilizer.
- Remote control, which is convenient in terms of maintenance.
The South Korean boiler navien ace is fully equipped with Japanese automation. At the same time, the manufacturer gives a warranty period of 2 years. This is a fairly compact device with excellent technical characteristics. The instruction manual for Navien boilers makes it easy to understand all the intricacies of setting the device, modes and temperature ranges.
Classification
Navien Ace gas boilers are divided into two categories:
- Ace ATMO.
- Ace TURBO.
The first unit is a simple and traditional boiler with an open combustion chamber, where the atmospheric removal of combustion products is used. The second is more advanced and has a turbocharged burner. This makes it possible to efficiently supply gas and burn it with unstable supply, which is associated with pressure surges. In addition, the second option is equipped with a special SMPS control system, which is based on highly sensitive chips. They are responsible for monitoring and regulating gas combustion processes. In all other respects, both options are no different from each other.
Both models can be classified as universal equipment. Adapted to difficult operating conditions, they are considered one of the most economical heating devices that are present on the Russian market today. An important component of the design is the remote control. This is very convenient when you can set modes and indicators at a distance, quickly adjusting.
But what is surprising is that they can work not only in automatic mode, but also in manual mode. This is especially convenient when the temperature outside the window changes dramatically. Manual installation allows you to more accurately set the parameters and indicators, which eliminates the smallest errors during the operation of heating equipment.
Navien ace gas boilers can be called universal units. They work on natural main gas or on a liquefied balloon. To switch from one type of gas to another, you only need to change the burner. No other changes are required.
What to pay attention to when installing?
Steel gas boiler Navien Ace
Since the instructions are attached to the equipment, there are no problems with installing and connecting the device. Doing it yourself is not a problem. Even a non-professional can understand the instructions. Moreover, it is written in Russian.
The only thing that experts ask to pay attention to is the method of removing carbon monoxide gases. They can be removed through a conventional atmospheric chimney connected to the smoke exhaust system of the house or installed as a separate structure. But if you are not satisfied with any option, you can make a coaxial chimney. Its installation is much easier. But keep in mind that coaxial structures are used only when the heated area of \u200b\u200bthe house does not exceed 110 m². They can be installed with boilers whose power does not exceed 11 kW.
Conclusion on the topic
Navien Ace gas boilers are high-quality heating equipment with excellent technical and operational characteristics. Adapted to the difficult Russian operating conditions, they have firmly taken one of the leading positions in the Russian heating equipment market. Their popularity does not fall, which means that there is a high probability that other models will always be in demand.

Since most models of wall-mounted boilers use a closed combustion chamber, they are equipped with turbocharging and a coaxial (pipe-in-pipe) chimney.
The power of Navien Ace boilers depends on the model and varies between 7-40 kW. True, there are no special differences in the principle of operation of the Navien boiler - it functions according to classical scheme, which uses a combustion chamber, burner and heat exchanger.
Important! The APS mechanism, on the basis of which the double-circuit version of the Navien boiler operates, ensures uninterrupted combustion and gas savings. A speed-controlled fan ensures safe combustion.
The most popular models of wall-mounted boilers Navien Ace
The most reliable Navien boilers, the operation of which can only be found positive reviews, are distinguished by an optimal price-quality ratio. They are divided into two categories:
- Ace ATMO. Traditional boiler with an open combustion chamber. Equipped with atmospheric removal of combustion products.
- Ace TURBO. An improved boiler equipped with a turbocharged burner and a special SMPS control system that regulates the process of gas combustion.
Important! Navien Ace gas boilers can operate both in automatic and manual modes, which allows you to more accurately set the parameters of the boiler and eliminate errors in operation as much as possible.
What to look for when installing Navien Ace boilers
Since detailed Russified instructions are attached to the Navien boiler, there are no special problems with its installation and launch - you can mount the equipment yourself.
However, experts advise paying attention to the combustion products removal system. They can be discharged through a standard chimney or installed as a separate structure. If the indicated methods of exhaust gases are not suitable, a coaxial chimney can be installed.
Important! Coaxial chimneys can be used in rooms whose area does not exceed 110 sq.m with a boiler power of not more than 11 kW.
The most common malfunctions and elimination of problems in the operation of the boiler
With its functionality and provision with electronics, there are certain disadvantages and malfunctions that can be encountered during the operation of the Navien Ace boiler.
Most often, users are faced with a problem when the unit stops working, and the electronics signal a critical error. This situation can be caused by various factors, including the sensitivity of the sensors. The most common mistakes:
- Smoke removal. Fault code "10" indicates problems with the removal of combustion products. Possible causes: turbine malfunction, pressure sensor tubes connected incorrectly, chimney clogged, nozzle too long.
If none of these causes are identified, and the Navien Ace boiler continues to signal an error, then normal gusts of wind may be the cause. You can solve this problem by redoing the chimney. As a quick response option, you can open the boiler body and disconnect the air supply hose. However, this measure is temporary.
For common mistakes on the Navien gas boiler, see this video:
- Flame sensor failure. Fault code "03" may indicate poor gas quality. The problem can only be solved by elimination. First of all, the cleanliness of the gas supply nozzles is checked. If they are in order, you need to choose the optimal position of the controller electrode (it must be in the hot phase of the flame).
- Equipment overheating. Fault code "01". Possible reason– blockage of the heating system, malfunction circulation pump or reduced flow. Ways to solve the problem: check the system and filter for the presence of air, check the health of the pump and the resistance of the coil for a short circuit, check the impeller in the circulation pump.
- Navien gas boiler is working, There is heating but no hot water. Error code "02". There is a jump in water temperature on the remote control (it rises sharply to a maximum and instantly drops). Perhaps there is a blockage in the hot water system. The reasons may be: lack of pressure in the water supply system, airiness of the system, the circulation pump cannot gain momentum, the distribution valve is closed, or the flow controller does not work. To eliminate this malfunction, first of all, it is necessary to adjust the pressure, bleed the air in the system, check the resistance of the pump coil and the impeller for damage, open the boiler distribution valve, disassemble the regulator housing and clean the box.
In addition, when hot water is turned on, the Navien boiler may hum or make an incomprehensible noise. At the same time, there is no error information on the display and the pressure is normal. As a rule, this is due to clogging of the heat exchanger. To fix the problem, you can clean the heat exchanger or replace it.
Did you know? It is best to choose boilers that are equipped with smooth adjustment - this will allow you to change performance depending on the air temperature.
Navien Ace gas boilers are distinguished by high quality and reliability in operation. However, the duration and features of operation depend on how correctly you were able to install and configure the Navien Ace boiler, as well as on the quality of the fuel used.
Repairing household appliances is a costly business. But it is not always necessary to call the master, in many cases you can do it on your own. Consider the Navien repair manual.
Navien is Korean-made heating equipment, popular in Russia due to its good price / quality ratio.
Here are the main design advantages of gas units:
- the control unit is equipped with a microprocessor chip with the function of protecting automation from power surges;
- automatic maintenance of the operating mode, many settings;
- long service life;
- can work on natural and liquefied gas;
- coolant pressure drop to 0.1 bar is allowed without equipment failure;
- the system does not freeze in the event of interruptions in gas supply. In a normal situation, when the temperature drops to +5, the burner automatically turns on. If ignition is not possible, the forced circulation pump operates, this does not allow the coolant to freeze;
- easy intuitive mode adjustment.
12E - the fire in the combustion chamber went out.
13E - short circuit in the flow meter.
14E - gas supply is stopped.
15E - problems with the control board.
16E - overheating.
17E - DIP switch failure.
18E - overheating of the smoke exhaust device.
27E - air pressure sensor problems.
If the boiler is noisy during operation, and the error is not displayed on the display, the reason may be scale, which impedes the flow of the coolant. The boiler makes noise when overheating, boiling water, or when the quality of the coolant is poor.
A frequent malfunction of the gas double-circuit wall-mounted boiler Navien is the failure of the three-way crane (). This occurs, in particular, when the service life of the crane has ended (usually 4 years). In this case, it may fail hot water in the DHW circuit.
Troubleshooting
Let's consider how to eliminate the main malfunctions of a gas boiler. With error 01, you need to carefully inspect the pump, check the condition of the impeller, electrical unit, clean the dirt filter, and also bleed air from the system.
To eliminate error 02 of the Navien boiler, perform the following steps:
- bleed air from the system;
- measure pressure;
- check the resistance on the pump coil, make sure there is no short circuit;
- check the position of the distribution valve, open if closed;
- clean the sensor box.
Error 03 of the Navien boiler is often displayed if the flame sensor is clogged. It should be cleaned. Gray coating on the electrode is cleaned off with fine-grained sandpaper. When an error 5 appears, you need to check the condition of the circuit section between the sensor and the controller, in case of serious problems, replace the sensor.
In case of error 10 of the Navien boiler, you need to:
- check the condition of the fan, if it is impossible to repair it, replace it;
- check the contacts in the tubes of the measuring device;
- clean the chimney.
When 13 errors appear, replace the sensor. Noise in the system may disappear after flushing the heat exchanger, sometimes it needs to be replaced. The taps should be opened completely, it is recommended to lower the temperature of the coolant.
Another important point in servicing the Navien gas boiler: how to refill the system after draining. Such a need may arise after repair / replacement of parts of the system or if the coolant was drained while the house was empty.
Before starting refueling, it is necessary to de-energize the devices, turn off the gas. Check the position of the valves, shut-off and distribution, open them to the maximum. Turn the make-up tap (usually at the bottom of the unit) to the left. Close when the pressure gauge shows 1.2-2 bar. If, as a result of filling, an alarm indicator goes off, the water is drained and everything is done again.
Conclusion
Do-it-yourself repair of the Navien mounted boiler is in many cases possible and acceptable. To maximize the uptime of the unit, the manufacturer's instructions must be strictly followed during the installation and operation of the heating system.
For preventive purposes, it is desirable to supplement the system with several devices: a gas and water filter, a water converter (magnetic, polyphosphate). To protect sensitive electronics, it is recommended to connect the boiler through a voltage stabilizer ().
