Features and types of Navien boilers
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 the automation from power surges;
- automatic maintenance of operating mode, many settings;
- long service life;
- can operate on natural and liquefied gas;
- coolant pressure is allowed to drop to 0.1 bar without equipment failure;
- the system does not freeze in the event of gas interruptions. In a normal situation, when the temperature drops to +5, the burner automatically turns on. If ignition is impossible, the forced circulation pump operates, this prevents the coolant from freezing;
- easy, intuitive adjustment of modes.
Diagram of the Navien gas boiler.
The power of Navien gas boilers varies in the range of 11-37 kilowatts. The brand’s assortment includes wall-mounted (what are gas boilers for heating a house), floor-standing (floor-standing gas boilers for heating a house), condensing models (what is a condensing boiler), with open and closed chambers, as well as diesel units. Wall-mounted boilers are equipped with corrosion-resistant heat exchangers made of high-carbon stainless steel.

The most common error codes
- The explanation of error codes is contained in the instruction manual.
- 01E – equipment overheats. The reason is a blockage or malfunction of the circulation pump.
- 02E – problems with coolant circulation.
- 03 – there is no signal about the occurrence of a flame. Associated with gas supply problems;
- 05E, 06E - indicate problems in the coolant temperature measurement circuit, including a possible short circuit;
- 07E, 08E – circuit sensor is faulty;
- 09E fan malfunction;
- 10E – problems with smoke removal;
- 12E – the flame in the burner went out;
- 14E – no gas supply;
- 16E, 18E – equipment overheating;
- 27E – problems with the air pressure sensor.
Troubleshooting
Let's look at how to fix the main problems with a gas boiler. If error 01 occurs, you need to carefully inspect the pump, check the condition of the impeller and electrical unit, clean the dirt filter, and also remove 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 flag.

Do-it-yourself replacement of units
Some units and components are replaced or cleaned independently. It is recommended to order and purchase spare parts from Navien dealers.
Before opening the lid, it is recommended to disconnect the boiler from the water, gas and electricity supplies. Here are some examples of replacement.
To replace the fan, and it is only replaced as an assembly, you should:
- Disconnect the gas line.
- Remove the hose between the fan and the air sensor.
- Disconnect the connectors (there are two of them) connecting to the control unit.
- Unscrew the screws (3 pcs.) and pull out the fan. Next, install a new one and return everything to its previous state in the reverse order.
In the video you can see how to flush the Navien boiler:
If you change the main heat exchanger, then you need to do it as follows:
- First remove the following units - gas supply pipeline, ignition transformer, fan and overheating sensor.
- Then disconnect the grounding, unscrew the fastening screws and remove the combustion chamber.
- Next, unscrew the mounting screws (8 pcs.) and remove the flue gas collector.
- After this, unscrew the screws holding the combustion chamber cover (9 pcs.) and unscrew the screws connecting the heat exchanger to the combustion chamber body (6 pcs.)
- Pull out the heat exchanger and install a new one, performing the steps in reverse order.
If the heat exchanger is cleaned and there is no damage, then use the old one. But be sure to check the integrity of the ceramic seal. If necessary, it is changed.
How to properly adjust and start
Procedure:
- The boiler startup procedure begins with filling with water. Gas dual-circuit units do not need to install additional devices, so you just need to open the make-up valve and increase the pressure to 1.5-2 At.
- After this, the valve is closed, air pockets are removed from the system and on the unit itself, for which Mayevsky valves on the radiators and an air valve in the boiler are used.
- Then you need to bleed the air from the circulation pump. The casing is removed and the water heating controls are turned on. Specific sounds appear, indicating the operation of the system. On the pump, gradually unscrew the screw in the middle until water appears. This procedure must be done 2-3 times, after which the air from the pump will be completely removed.
- As soon as the circulation pump is brought into operation, the burner will start electronically and the heating system will begin to function.
This completes the initial startup and adjustment procedure.

Possible causes of malfunctions and ways to eliminate them
Accurate determination of the cause of failure of system elements can facilitate their repair. Based on the codes, you can understand which one has stopped performing its functions normally. Most often, owners of Navien Deluxe boilers encounter the following problems:
- 01E. Overheating of the system can be caused by blockage in the ducts or malfunction of the water pump.
- 02E. There may be air in the system, insufficient water, the water pump impeller is damaged, or the flow sensor has failed.
- 03E. The boiler has improper grounding, problems with the ion sensor, and a gas supply failure.
- 05E. Short circuit in a section of the temperature sensor circuit or lack of proper contact between it and its controller.
- 10E. The fan is faulty, the sensor tubes are not connected to the fan correctly, the chimney is clogged.
- 13E. The heating water flow sensor is located in the short circuit.
