THROUGH THE WALL INSTALLATION
(RECOMMENDED INSTALLATION)
To vent the unit through the wall, connect the pipe adapter
to the exhaust motor adapter. If the exhaust adapter is at
least 18-inches above ground level, a straight section of
pellet vent pipe can be used through the wall.
Your Forester 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-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) section of pipe should be added with a
horizontal cap, which would complete the installation (see
FIGURE 6).
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 your stove 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 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 ® or Metal-Fab ® kits.
THROUGH THE ROOF/CEILING INSTALLATION
When venting the stove 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-inch 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 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.
