Chimney Cleaning:
1.
Creosote Formation – 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 chimney flue, as a result creosote
residue accumulates on the chimney lining. When ignited creosote makes an
extremely hot fire which can damage the chimney or cause a house fire.
2.
Fly Ash – This can accumulate in the horizontal sections of a vent run. Fly ash is
non-combustible although if allowed to build up, continuously, it may impede the
exhaust flow.
3.
Inspection of Vent System – The chimney/venting system should be inspected
should be inspected annually or per ton of fuel to determine if creosote or fly ash
build up has occurred. To clean the chimney, detach the vent where it attaches to
the combustion blower. If creosote has accumulated it should be removed.
Inspect the entire vent system from unit exhaust to termination. Creosote should
be removed with a brush specifically designed for the type of chimney in use. It
is recommended that a qualified service technician perform the inspection and
required maintenance.
Glass Doors:
Gaskets around the door and window panes should be inspected, cleaned and repaired
when necessary.
