This method also provides natural draft in the event of a
power failure.
A cap should be installed on the chimney to keep out rain.
Combustion air is provided from the living area and enters the
feed system from around the wing and stove body spaces.
The chimney top must be capped to
prevent rain and/or snow from entering
the chimney.
See Figure 4.8, for information on the
optional Harman®Adjustable Stainless
SteelIntakeExtension.
The damper area must be sealed with
a non-combustible material and it is
recommended that Kaowool, mineral
wool, or an equivalent non-combustible
insulation be placed on top of the
sealed area to reduce the possibility of
condensation. Insulation alone should
not be used to seal the damper opening.
