THROUGH THE WALL INSTALLATION
To vent the unit through the wall, connect the pipe adapter to the exhaust motor adapter. If the exhaust adapter is at least
24-inches above ground level, a straight section of pellet vent pipe can be used through the wall.
Your furnace dealer should be able to provide you with an installation kit, which will
the proper clearance through a combustible wall. Once outside the structure, a 3-inch 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-foot (minimum) vertical 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-feet 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-feet to get above the
snowdrift line. This same installation can be used if
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 3-foot 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
THROUGH THE ROOF/CEILING INSTALLATION
When venting the furnace through the ceiling, the pipe is connected in the same manner as a wall installation, except
the clean-out tee is always on the inside of the house, and a 3-inch adapter is placed in front of the clean-out tee.
You must use proper ceiling support fl anges and roof fl 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 15-feet, the pellet vent
pipe size should be increased to 4-inches in diameter.
Do not exceed more than 4-feet 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.
