VENT TERMINATION CLEARANCES
A. Minimum 4-foot (1.22m) clearance
below or beside any door or window
that opens.

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 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
(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.
