A. Minimum 3-foot (0.91m) clearance from an forced
air intake of any appliance.
B. Minimum 2-foot (0.61m) clearance below eves or
overhang.
C. Minimum 1-foot (0.3m) clearance horizontally
from combustible wall.
D. Must be a minimum of 3 foot (0.91m) above the
roof and 2 foot (0.61m) above the highest point or
the roof within 10 feet (3.05m).
THROUGH THE WALL INSTALLATION
(RECOMMENDED INSTALLATION)
TYPICAL THROUGH THE
WALL 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 anges and
roof ashing (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.
