INSTALLATION
WARNING: Before installing
in a solid fuel burning fireplace,
the chimney flue and firebox
must be cleaned of soot, creo-
sote, ashes and loose paint by
a qualified chimney cleaner.
Creosote will ignite if highly
heated. A dirty chimney flue may
create and distribute soot within
house. Inspect chimney flue and
firebox for damage. If damaged,
repair flue and firebox 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.
