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.
TYPICAL THROUGH THE
WALL INSTALLATION
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.
