Why does the flame fail to form in my Hegwein Indoor Fireplace?

  Oscar ThompsonAug 9, 2025
  If your Hegwein Indoor Fireplace flame fails to form, several factors could be at play. It might be due to a defective air flap or valve, which would require replacement. Alternatively, throttle organs might be closed, needing to be opened, or the supply line could be blocked, requiring unblocking. The supply line might be too long, needing adjustment, or the gas supply line might still be inert with N2, requiring several ignition attempts. Other possible causes include a defective gas valve (requiring replacement), an incorrect gas-to-air ratio (requiring a settings check), or using the wrong type of gas (ensure you're using the gas specified on the rating plate).

Why does fault shutdown take place during operation of my Hegwein Indoor Fireplace?

  If your Hegwein Indoor Fireplace experiences a fault shutdown during operation, it could be due to fluctuating combustion chamber or supply pressure levels, leading to flame blow-off. Check the pressure settings and consider a differential pressure regulation system. Another cause might be the pilot flame being influenced by the main flame or being suffocated, which would require repositioning the gas fired igniter. Lock-out can also occur if a flame is signaled before the gas valve opens, necessitating replacement of the gas valve. Finally, a defective ionization flame monitor can also cause this issue, requiring replacement.

  If the gas fired igniter and control unit are operational, but no signals are transmitted via the integrated flame relay in your Hegwein Indoor Fireplace, the integrated fuse may be defective. Replace the fuse.

How to troubleshoot spark not forming in Hegwein Indoor Fireplace?
- N
  Norman RochaSep 1, 2025
  If the spark does not form in your Hegwein Indoor Fireplace, there are several potential causes. The gas fired igniter may not be receiving voltage, so check the wiring and control system. The ignition electrode could be burned out, requiring cleaning and replacement. The electrode distance might be too large or short-circuited; clean the igniter and adjust the electrode distance to 2-3 mm. A defective spark transformer will need to be exchanged. Scale on the spark electrode or earth rod/bolt should be removed. Finally, a broken ceramic insulator needs replacement.

What to do if the flame comes on for a short time, but trips once the ignition safety time has elapsed in Hegwein Indoor Fireplace?

  Kelly SpencerNov 14, 2025
  If the flame on your Hegwein Indoor Fireplace comes on briefly but then trips after the ignition safety time, several issues could be the cause. The flame rod might be burned out, deformed, or short-circuited, necessitating replacement and adjustment. A broken ceramic insulator on the flame rod would also require replacement. If using a Hegwein control unit, ensure the operating voltage lags behind the bias voltage by at least 5 seconds, keeping the bias voltage switched on. If using a different manufacturer's control unit, switch off the ignition voltage approximately 0.5 seconds before the ignition safety time expires. Overheating of the gas fired igniter can also cause this issue, so leave the fan air running for cooling. Incorrect gas and air operating pressure settings can misalign th...
