#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.
keep any materials that may be affected by the
elevated exhaust temperatures at least 3 feet
away from the flue termination
