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"(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"(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 (see FIGURE 7).
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"(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"(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.
