Harman Stove Company PB 105 manual Outside Air

	Installation
		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
Inlet Cover part#	Fig. 6	is best located on the exterior wall oriented toward the
1-10-09542		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
Outside Air Pipe		area where drifting of snow or ice will build up, block-
		ing the intake air supply.
Knockout
		The Outside Air knockout is located on the face of
		the Feeder Cover. It is pre-cut except for several small
Feeder Cover		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.
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
Outside Air Inlet Pipe		supplied)
