Troubleshooting
Does flue gas escape around the draught
hood?
Negative pressure in the flue pipe >3 Pa?
Is the flue pipe blocked?
Is the size of the chimney OK?
Are fans used in the boiler room, which
extract air from the room (extractor hoods,
dryers ...)?
Are deposits or fibre contamination visible
on the heat exchanger surface?
Visual check through the clean-out cover
and combustion chamber.
Remedy
Determine and remedy the cause for
insufficient flue draught. Shut the burner
down, if the fault cannot be remedied
immediately.
Clean the boiler dry or, if required, wet.
