INSTALLING THE
OUTSIDE AIR KIT
Combustion air is fed to the fi rebox through a
connection on the rear lower left side of the unit.
A free fl owing supply of air must be available to
this opening at all times. Combustion air may be
taken from inside the building if the local building
code allows, but performance may suffer. Also,
it must go through the 6" (152mm) duct to the
connection on the left hand side.
Air drawn from the interior of the building will
affect the performance of gas or oil furnaces,
and exhaust fans and fan driven appliances.
This may cause a negative pressure in the
house allowing smoke to back into the home.

The preferred source of combustion air is from
outside the building. If possible, install the kit
on the wind loading side of the building not the
leeward or (negative pressure) side.
Note: Do not obtain combustion air from
attic, garage or other enclosed
space.
1) Put the supplied insulated air duct to a nearby
exterior wall. Maximum length of duct is 20ft
(6.1m). Duct length should be kept to a
minimum and as straight as possible. Note:
4 ft. only is supplied with unit. Termination
should be in an area with good air fl ow.
2) Ensure that your air source is not close to
automobile exhaust, gas meters or other
vents.
