Inspect frequently and clean when necessary. Fly ash will
accumulate at all bends in the exhaust system.
Note: Large amounts of fly ash build-up will create a lack
of combustion air. Removing the clean out tee cap on
vertical installations will allow an inspection of the ash
build-up in the clean out tee and will help you to decide
how frequently more extensive cleaning must be per-
formed.
