Possible Causes

Dust burning off heat exchanger, Flue gas leakage at seals, Overheating electrical component on Weishaupt control, Oil or gas leak at burner connections

How to Fix / Troubleshooting

Safety first: If you smell gas or strong flue gases, switch off the boiler, ventilate the area, and do not use naked flames. Evacuate if necessary.

  • Initial operation: A slight burning smell may be normal after installation or servicing as oils and dust burn off. This should dissipate quickly.
  • Check flue joints: Inspect visible flue connections for signs of leakage (staining, soot). Do not operate the boiler if flue leaks are suspected.
  • Inspect wiring: Look for discoloured or melted insulation on wiring and components. Replace any overheated parts.
  • Check for oil/gas leaks: For oil burners, look for wet spots around oil lines. For gas, a licensed technician should perform a leak test.

When to call a professional: Any persistent or strong odour should be investigated by an authorised Weishaupt or heating technician.
