TYPICAL THROUGH THE WALL 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 in.(457mm) 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 in.(76mm) 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.
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 in.(76mm)
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 15ft (4.57m),
the pellet vent pipe size should be increased
to 4 in. (102mm) 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.
