INSTALLATION
THROUGH THE WALL INSTALLATION
(RECOMMENDED INSTALLATION)
Canadian installations must conform to CAN/CSA-B365.
To vent the unit through the wall, connect the pipe adapter
to the exhaust motor adapter. If the exhaust adapter
is at least 18” (457 mm) above ground level, a straight
section of pellet vent pipe can be used through the wall.
Your heater dealer should be able to provide you with a
kit that will handle most of this installation, which will
include a wall thimble that will allow the proper clearance
through a combustible wall. Once outside the structure,
a 3” (76 mm) clearance should be maintained from the
outside wall and a clean out tee should be placed on the
pipe with a 90-degree turn away from the house. At this
point, a 3ft (0.91m) (minimum) section of pipe should be
added with a horizontal cap, which would complete the
installation. A support bracket should be placed just below
the termination cap or one every 4ft (1.22m) to make the
system more stable. If you live in an area that has heavy
snowfall, it is recommended that the installation be taller
than 3ft (0.91m) to get above the snowdrift line. This same
installation can be used if your heater is below ground level
by simply adding the clean-out section and vertical pipe
inside until ground level is reached. With this installation
you have to be aware of the snowdrift line, dead grass, and
leaves. We recommend a 3ft (0.91m) minimum vertical
rise on the inside or outside of the house. The “through
the wall” installation is the least expensive and simplest
installation. Never terminate the end vent under a deck, in
an alcove, under a window, or between two windows. We
recommend Simpson Dura-Vent® or Metal-Fab® kits.
THROUGH THE ROOF/CEILING
INSTALLATION
When venting the heater through the ceiling, the pipe is
connected the same as through the wall, except the clean-
out tee is always on the inside of the house, and a 3” (76
mm) adapter is added before the clean-out tee. You must
use the proper ceiling support flanges and roof flashing
(supplied by the pipe manufacturer; follow the pipe
manufacturer’s directions). It is important to note that
if your vertical run of pipe is more than 12ft (3.7m), the
pellet vent pipe size should be increased to 4” (102 mm)
in diameter. Do not exceed more than 4ft (1.22m) of pipe
on a horizontal run and use as few elbows as possible. If
an offset is required, it is better to install 45-degree elbows
rather than 90-degree elbows.
