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.

#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 Page 13 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 Kaowool,
Mineral wool or an equivalent
non combustible insulation is
used on top of the plate to reduce
the possibility of condensation.
Insulation alone should not be
used to seal the damper opening.
