Outside Air
To install outside air, use 2 3/4” I.D.galvanized
steel flex pipe, part # 2-00-08544 ( 12’ 6” length) or part
# 2-00-08545 ( 25’ length) See Fig. 6. There is a break-
away hole on the rear panel which must be removed
before connecting the flex pipe. See Fig. 7.
When the appliance is side wall vented: The air
intake is best located on the same exterior wall as the
exhaust vent outlet, and located lower on the wall than
the vent outlet.
When the appliance is roof vented: The air intake
is best located on the exterior wall oriented toward the
prevailing wind direction during the heating season.
Never terminate the outside air above the vent pipe
outlet. The maximum length of this pipe is 20 feet. Inlet
cover part number 1-10-09542 should be used to keep
birds, rodents etc.out of the inlet pipe. See Fig.6.
NOTE: The inlet cover should not be placed in an
area where drifting of snow or ice will build up, block-
ing the intake air supply.
The Outside Air knockout is located on the face of
the Feeder Cover. It is pre-cut except for several small
tabs. There is also a filler plate screwed to the inside
to cover the top of the hole after the Outside Air Pipe
has been installed. This will allow for removal of the
Feeder Cover without disconnecting the Outside Air
Pipe. See Fig. 7.
Only metal Intake Flex should be used for the
Outside Air Supply connection.
The Outside Air Intake Pipe is inside the Feeder
Cover and to the right of the feeder motor. The 2 3/4”
steel flex pipe is made to slide over the outside of the
Air Intake Pipe. See Fig. 8. It should be held into place
with some silicone, foil tape, or a hose clamp. (not
supplied)
Heat Reclaiming Ventilation System (HRV)
When installing in a house with a Heat Reclaim-
ing Ventilation System (HRV) be sure the system is
balanced and is not creating a negative pressure in the
house.
