Advantages and disadvantages of Navien Deluxe

Boilers are sold for more than 30 years on the global market. Their functionality and dependability have helped them become more popular. Several protection systems guarantee the high degree of safety of gas equipment.

1. From freezing of the heating system, in the case of prolonged shutdown of the equipment in the cold season.
2. From destructive modes of operation of the electrical network, in case of voltage surges.
3. From low operating conditions of the gas network.
4. From emergency modes of operation of the water supply, with a decrease in the pressure of the coolant to 0.1 bar.

Safety unit Primary temperature and pressure sensors, a control manometer, and a safety relief valve to prevent overpressure in the heating circuit are all included in the Navien boiler. A filter for water purification from hardness salts is installed to prevent scaling on the interior surfaces of water heating systems.

An integrated SMPS chip in the electronic board of the boiler unit control system guards against network fluctuations of up to 30% relative to the standard 220V voltage.

Russian consumers report a few minor drawbacks with this brand of heating sources, including its relatively high cost, reliance on energy, and complicated gas boiler installation that is best left to specialized companies.

Technical characteristics

The temperature sensor sends out a signal to the remote control panel found on modern Navien units.

Its measurements are immediately sent to the control unit’s chip, which instructs the executive mechanism to adjust the gas supply to the two-circuit boiler’s flow rate. Similarly, in the event that the unit is operating in an emergency, a command to completely shut it down may be issued.

The most common versions of Navien gas boilers are wall-mounted, two-circuit models with closed furnaces that have a heat output of 20–24 kW. These units can heat a room up to 160–240 m³ and provide enough hot water for a family of four.

Basic errors and their elimination

Gas boilers come with a good diagnostic system that checks the boiler’s parameters minute by minute and, should any be violated, outputs a coded signal to the working panel so that the fault can be fixed:

The primary Navien gas boiler failure codes are:

1. E01 – overheating of the coolant in the boiler. Insufficient water circulation through the unit, it is necessary to check the pump operation, leaks and clogs in the heat exchanger. If the latter is detected, before eliminating the error, it is recommended to wash the heat exchanger from scale according to the technology specified by the manufacturer.
2. E02 – error 02, low pressure of the heating medium in the heating circuit. Check leaks in the heating network, if necessary make up the circuit.
3. E03 – problems in the electric ignition system of the boiler. It is necessary to check the presence of power supply in the system, the presence of pressure and the electrode for the presence of a spark.
4. E04 – no flame in boiler. Checking the piezo igniter for the possibility of spark production and checking the grounding system.
5. E05 – return temperature sensor at the inlet to the unit is not working. Check the functionality of the primary temperature sensor and, if necessary, replace it with a similar option.
6. E06 – temperature sensor of the supply heating medium at the boiler outlet does not work. Check the operation of the primary temperature sensor and if necessary replace it with a similar version.
7. E07/08 – DHW temperature sensor at the boiler inlet or outlet does not work. Check operation of primary temperature sensor and, if necessary, replace it with a similar one.
8. E09 – centrifugal fan does not work. Check the operation of the inlet air filter for clogging.
9. E10 – error 10, problems in the smoke exhaust system, no vacuum in the boiler. Check the gas exhaust ducts for blockage.
10. E13 – error 13, problems in the circulation circuit.

Installation and connection

The service department, along with gas equipment representatives from the state gas company, should install, adjust, and start up the Navien gas boiler upon modification for the first time.

To manage the installation and construction process, the owner of thermal equipment must understand the key components of boiler commissioning.

Installing a gas boiler in a damp basement room without supply ventilation is prohibited. These hinged units are typically installed in kitchens when available space permits, and floor versions are placed in furnace rooms specifically.

Basic guidelines for wall-mounted boiler positioning with Navien:

1. The boiler is installed on a capital wall made of heat-resistant materials.
2. The space from the boiler front to the opposite wall must be at least 1.0 in order to be able to service the device.
3. The distance from the boiler to any electrical appliance must be at least 0.6 м.
4. The space between the side of the boiler and the walls must be at least 0.2 м.
5. The space between the floor level and the bottom plane of the boiler must be at least 0.8 м.
6. The unit must have an independent power supply line 220V/50Hz.
7. The boiler drum must be earthed.
8. The room in which the gas appliance is installed must have a 3 times hourly supply ventilation system.
