VENT TERMINATION CLEARANCES
A. Minimum 4-foot (1.22m) clearance below or
beside any door or window that opens.
B. Minimum 1-foot (0.3m) clearance above any
door or window that opens.
C. Minimum 3-foot (0.91m) clearance from any
adjacent building.
D. Minimum 7-foot (2.13m) clearance from any
grade when adjacent to public walkways.
E. Minimum 2-foot (0.61m) clearance above any
grass, plants, or other combustible materials.
F. Minimum 3-foot (0.91m) clearance from an forced
air intake of any appliance.
G. Minimum 2-foot (0.61m) clearance below eves or
overhang.
H. Minimum 1-foot (0.3m) clearance horizontally
from combustible wall.
I. 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)
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.
