Cleaning and maintenance Cleaning (customer)
CAUTION!
Do not lubricate the washer and sealing area
Never lubricate the sealing area in the flue
duct or the washer on the air valve with oil,
grease or other lubricants. The reason for
this is because dust particles in the flue gas
adhere to the lubricant and cause encrustation and
sluggishness.
Check if the seal on the cover is intact and replace if
necessary.
