Installation
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 King/Ashley 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 7).
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.
