#1 Preferred method
This method provides excellent venting for normal operation
and allows the stove to be installed closest to the wall. Two
inches from the wall is safe; however, four inches allows
better access to remove the rear panel. The vertical portion of
the vent should be three to five feet high. This vertical section
will help provide natural draft in the event of a power failure.
Seal pipe joints with silicone or aluminum tape in addition to
the sealing system used by the manufacturer.
Note: Do not place joints within wall pass-through.

#2 Preferred method
This method also provides excellent venting for normal
operation but requires the stove to be installed farther from
the wall. The vertical portion of the vent should be three to
five feet high and at least three inches from a combustible
wall. This vertical section will provide natural draft in the event
of a power failure.
Seal pipe joints with silicone or aluminum tape in addition to
the sealing system used by the manufacturer.
If the stove is installed below grade be sure the vent
te
rmination is at least 12" above grade. The outlet must also
be 1 foot from the house/building.
Note: Do not place joints within wall pass-through.
