for inspection of vent pipe.

venting components specifically approved and
labelled for this stove may be used.

combustible materials is one (1”) inch (25 mm),
except where stated otherwise.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting must be installed on a level plane
without an inclining or declining slope.
There must not be any obstruction such as bushes,
garden sheds, fences, decks or utility buildings within
