Termination Location and Vent Information
A. Venting Termination Design
#1 Installing into an existing fireplace chimney
This method provides excellent venting with 100% outside air
which is the most efficient operation of this unit. This method
also provides natural draft in the event of a power failure.
A 4” stainless steel flex pipe is needed for the flue pipe, and 3"
aluminum or Stainless Steel Flex Pipe is used for the intake.
CHIMNEY CONNECTOR PIPE MAY NOT PASS
THROUGH CONCEALED SPACES INCLUDING AN
ATTIC, ROOF SPACE, CLOSET, FLOOR OR CEILING.
Height of existing hearth
#2 Installing into an existing fireplace chimney
This method provides excellent venting for normal operation.
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
Steel Intake Extension.
The damper area must be sealed with a
steel plate and it is recommended that
Kaowoll, 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. For quick and easy
installation, purchase the steel Harman
Block Off Plate, 1-00-25625.
