Vent Termination Clearances - PFS 5520 Mode D'emploi

VENT TERMINATION CLEARANCES

A. Minimum 4-feet (1.22 m) clearance below or beside
any door or window that opens.
B. Minimum 1-foot (0.3 m) clearance above any door or
window that opens.
C. Minimum 3-feet (0.91 m) clearance from any adjacent
building.
D. Minimum 7-feet (2.13 m) clearance from any grade
when adjacent to public walkways.
E. Minimum 2-feet (0.61 m) clearance above any grass,
plants, or other combustible materials.
F. Minimum 3-feet (0.91 m) clearance from an forced air
intake of any appliance.
G. Minimum 2-feet (0.61 m) clearance below eves or overhang.
H. Minimum 1-foot (0.3 m) clearance horizontally from combustible wall.
I. Must be a minimum of 3 feet (0.91 m) above the roof and 2 feet (0.61 m) above the highest point or the roof
within 10 feet (3.05 m).
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 3 ft (0.91 m) 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 4 ft (1.22 m) 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 3 ft (0.91 m) 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 require a 3 ft (0.91 m)
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 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 12 ft (3.66 m),
the pellet vent pipe size should be increased to 4" (102 mm) in diameter. Do not exceed more than 4 ft (1.22 m)
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.
