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. Because dust
particles in the flue gas adhere to the
lubricant and cause encrustation and sluggishness.
Inspect the integrity of the seal on the cover and
replace, if necessary.
