WARNING: Before installing
in a solid fuel burning fireplace,
the chimney flue and firebox must
be cleaned of soot, creosote,
ashes and loose paint by a quali-
fied chimney cleaner. Creosote
will ignite if highly heated. A dirty
chimney flue and firebox may cre-
ate and distribute soot within the
house. Inspect chimney flue for
damage. If damaged, repair flue
before operating heater.
WARNING: Seal any fresh
air vents or ash clean-out doors
located on floor or wall of fire-
place. If not, drafting may cause
pilot outage or sooting. Use a
heat-resistant sealant. Do not
seal chimney flue damper.
