Outside Air
Here arefourbenetsof outside air:
1. Having air introduced from outside the living area
boostsoverallefciency.
2. It eliminates draft problems that can occur in tight
homes.
3. It reduces smoke spillage in the event of a power
failure.
4. It allows your vent termination to be as close as
18" from windows or doors.
Outside air is optional except in mobile
homes and where building codes require. The
benetofoutsideairismainlynoticedinsmall,very
tight, houses.
To install outside air use 2 3/8" I.D. non-
combustibleexpipe.Thereisabreak-awayhole
on the rear panel of the P68 stove which must be
removedbeforeconnectingtheexpipe.The pipe
should be run outside and terminate to the side or
belowtheventpipeoutletsotheueoutletismore
than 12" from the inlet cover. The maximum length
run of this pipe is 15 feet. If a longer run is needed
the size must be increased to 3". Inlet cover part
number 1-10-08542 should be used to keep birds,
rodents, etc.out of the pipe.
You may choose to use the optional Direct Vent
Wall Passthrough Kit (part #1-00-677077) which
incorporates the venting passthrough and outside
air inlet into one component.

balanced and is not creating a negative pressure in
the house.
