WHEN OPERATING WITH EITHER LIQUID OR SOLID FUEL...
When operating the heater in solid fuel
mode, a buildup of creosote can
accumulate on the inside surface of the
stack assembly that may result in a fire
inside the stack. To prevent creosote
buildup when operating with solid fuel,
the stack assembly should be cleaned
daily with a brush or rag. Failure to do
so may result in a fire causing severe
injury or death.
Check inside of stack sections (1) and
stack cap (2) for thick deposits of
carbon/soot or creosote, and clean if
necessary. Check for cracked sections
or bent flanges which may cause the
leakage of exhaust gases into heated
space during heater operation.
Stack or stack cap assembly have
an accumulation of carbon/soot or
creosote buildup which would impair

is not bent, and that it does not have
holes in it.
Burner cover assembly bent or has
holes in it which would prevent it
from sealing off air leaks in liquid or
solid fuel operation.
