Outside air
Here a re four benefits of outside air:
1. Having air introduced from outside the living
area boosts thermal efficiency. Because the make
up air is not being drawn in through leaky windows
or doors.
. Outside air connection eliminates draft problems
that can occur in tight homes.
3. Outside air connection reduces smoke spillage in
the event of a power failure.
4. Outside air connection 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 benefit of
outside air is mainly noticed in small, very tight,
houses.
To install outside air use 3/8" I.D. non-combus-
tible flex pipe. There is a break-away hole on the
rear panel of the P43 stove which must be removed
before connecting the flex pipe. The pipe should be
run outside and terminate to the side or below the
vent pipe outlet so the flue 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
1-10-0854 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.
