wall pass-through and termination cap. The use of mis-matched or makeshift venting components may cause
exhaust spillage and/or increase fire risk.

#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.
Note: Do not place joints within wall pass-throughs.

#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.
If the stove is installed below grade be sure the vent
termination is at least 18" above grade. The outlet must also
be 1 foot from the house/building.
Note: Do not place joints within wall pass-throughs.
cautiOn
Keep any materials that may be affected by the
elevated exhaust temperatures at least 3 feet away
from the flue termination
