MAINTENANCE:
When wood is burned slowly, it produces tar
and other organic vapors, which combine
with expelled moisture to form creosote. The
creosote vapors condense in the relatively
cool flues of a slow burning fire. As a result,
creosote residue accumulates on the flue
lining. When ignited, this creosote makes an
extremely hot fire.
CLEANING:
1. Double wall connector pipe must
be installed so that access is provided for

2. The connector and chimney should be
