Cleaning the lower flue
After every week before ignition, open the furnace door, loosen the two
knurled nuts on the front cleaning cover, remove the front cleaning cover, and
use a vacuum cleaner to remove soot from the lower flue. When reinstalling,
make sure the unit is tight and no smoke is coming out.
