Answers : Gas boiler NAVIEN ACE

Make up system as organized? From the water mains through the non-return valve?

I would like to know if the heating system is new or old? No need to add pressure to the expansion tank. The tank contains nitrogen, not air, and the pressure is set to 1 atm from the factory. The system may have a leak that is difficult to detect. A slowly dripping drop has time to dry out on a pipe or radiator, but the pressure will drop. It also has the place to check makeup cocks, cocks Mayevsky.

And I would start by checking the pressure in the receiver, there should be air pressure not less than 1.5atm, then checked the air (emergency) valve, well, and all the taps. To help you look, turn off all the taps that are in the system and start opening one by one from the boiler and watch the pressure drop over the course of an hour. Perhaps in the system accumulated air and it is necessary to make a boost of the coolant (without a boost pumping the receiver useless).

Hello! Can you tell me whether it is possible to programmatically reduce the boiler output and if so, how to do it??

It is unlikely you would be able to do this.к.This is determined by the model of this particular boiler. (imho)

And the Fondital Tahiti 24CTFS has it?

tusat wrote : Hello! Can you tell me whether it is possible to reduce the boiler power and if so, how to do it?

The power of the boiler can be reduced to 13 kW.No loss of power on the DHW. To do this you set in a certain position the DIP.switches #9-10 on the boiler control unit.The settings for the different outputs are given in the user manual.

After installation check and adjust if necessary the gas pressure at the burner MIN and MAX.according to the installed power.

It’s true that without losing power to DHW? The maximum pressure on the burner at 24 is 88 and 16 is already 43, are you saying that with this difference the DHW will heat the same?

In domestic hot water preparation mode, the wall hung boilers automatically switch to maximum output.

How can it switch if it is jammed, t.е. Ordered no more no more? If it has a provision for adjusting the maximum heating output, usually it is software, knobs and buttons, then yes, and if you limit the supply with a valve, then finita la comedy.

Particular attention should be paid to the device of the lower part of the body, as here is the connection of the inputs and outputs of the circuits, and there are other important details.

Closer to the wall, there are 4 connecting pipes:

There is a hot water filter in front of the return inlet, and even closer there is a drain plug.

There is a make-up valve in front of the DHW outlet, which fills the system with water.

If the temperature continues to drop and it reaches.6 °, the burner is triggered, which heats the water to 21 °.

Modes of operation

Like many heating devices, boilers Navien have a winter and summer modes of operation. On the display, the button to change modes is indicated by the icon “Snowflake” and “Sunshine”.

By pressing this button repeatedly, you can change the options:

Adjust the temperature of the coolant on the remote control can be when the display lights up with the heating icon.

In some models, to do this, it is necessary to press the button “Heating mode”, in others, turn the knob with this pictogram.

Blinking radiator icon means that the figures you see show the set t of the heating medium.

If the “radiator” is simply lit. the actual temperature in the heating is displayed.

After selecting “radiator”, the “” or “-” keys must be pressed to increase or decrease the temperature. A few seconds after the desired temperature is set, the radiator icon stops flashing, and the display will show data on what t coolant now, and the device will begin to gradually heat it (or cool it down) to the selected.

Adjusting the temperature of the hot water supply

To increase or decrease the hot water temperature, press the faucet icon on the remote control.

By turning the knob, or adjusting the temperature with the “plus” and “minus” buttons, you can set the desired level of heating. It is advised to do this not during the showering, but beforehand.

Adjustment step is 1°C. Limits within which the temperature changes: from 30 to 60 ° C.

Precautions

The room where the boiler is located must be well ventilated.

Gas cylinders, if used, should be stored in a separate cool room.

Do not dry the clothes on the gas heating pipes.

Mains power supply parameters must correspond to the requirements of the particular model (e.g., 220V, 50 Hz).

The appliance must be plugged into a separate socket (no other appliances plugged into the socket), extension cords and adapters are not permitted.

Do not touch the housing with wet hands or plug it in.

The appliance must be in a protective casing when in operation.

Do not install or repair the gas equipment yourself. this is the work of public services. Once a year, these services will conduct a preventive inspection of the boiler.

If bubbles appear, turn off the gas valve immediately, vent the appliance and call the emergency service.

Cleaning the outside surface of the boiler body

Do not clean the machine when it is in operation. To clean the housing, de-energize it, turn off the gas and let it cool down.

After that you can wipe the tap with a soft cloth or a sponge.

Filling the boiler and the heating system with water

Error code 02, indicates that an attempt was made to start the boiler, but there is no water in the system, or it is not enough. What to do:

  • The appliance is unplugged and the gas supply is shut off.
  • In the bottom of the boiler, among many other elements, you must find the make-up valve. Turning it counterclockwise opens it and clockwise closes it.
  • When the valve is open, watch the pressure gauge readings. Close the tap when it shows 1.3. 2 bar.
  • Now the boiler is reconnected, the gas is supplied and the boiler is started.

Do not worry if error 02 reappears. This can be caused by the fact that after bleeding the air (which is automatically performed at start-up), the water level is again insufficient. The filling operation must be repeated.

Drainage of water from the boiler and hot water system

If the boiler will not be used for a long time (especially in winter), it is advisable to drain all water from the heating and DHW circuits. What to do:

  • De-energize the unit and turn off the gas valve.
  • Heating system valves (2 pcs.) and cold water.
  • Open the tap that you usually use (over the sink, for example) and drain the hot water from the system.
  • The tap in the DHW system is closed.
  • At the bottom of the housing, open the plug and drain the heating water.

Cleaning the heating water filter

The filters collect all impurities in the water.

Periodically they need to be cleaned, for this purpose:

  • Drain the water (see “Drain the water” on page 31). previous paragraph).
  • Wait for the equipment to cool down completely.
  • The filter is located near the drain plug. To remove it, first remove the mounting bracket, then pull out the filter itself.
  • Wash it under pressure, with clean water.
  • Then assemble in reverse order.

If the filters are not cleaned in time, the boiler will overheat.

Possible malfunctions and troubleshooting

  • 01. overheating (check if the pump works and the filter is not clogged).
  • 03. No gas (check whether the tap is open).
  • 04. false flame signal (check the gas valve, replace the electrodes or the board).
  • 05. 06. short circuit on the temperature sensor or breakage.
  • 09. fan defects.
  • 10. Problems with smoke exhaust (check if the fan works properly, if the chimney is not clogged, correct connection of the fan tubes, the reason could also be a gusty wind).
  • 013. Short circuit on the sensor of heating water flow.

If the boiler does not produce errors, but works much worse, the cause could be a clogged filter or air circulation in the system.
