CHIMNEY ENCLOSURE
REQUIREMENTS
Through Rooms: Interior chimneys shall be
enclosed where they extend through closets,
storage areas, or habitable spaces where the
surface of the chimney could be contacted by
persons or combustible materials. The space
between the chimney and the enclosure shall
be at least 2 inches. (Figure 2).
Multi-Story: The National Fire Protection
Association Standard #211 states: “ Factory-
built chimneys that pass through oors of
buildings requiring the protection of vertical
openings shall be enclosed with approved
walls having a re reistance rating of not
less than one hour when such chimneys are
located in a building less than 4 stories in
height, and not less than 2 hours when such
chimneys are located in a building more than 4
stories in height.”
Cold Climates: In cold climates, chimneys
mounted on an outside wall should
be enclosed. Exterior chases reduce
condensation and creosote formation, and
enhance draft. Include an access door by the
Tee Cleanout Cap for chimney cleaning. See
gure 23.
STOVE RECOMMENDATIONS
Follow the stove manufacturer’s instructions.
The requirements stated below pertain to
all stoves or other appliances installed with
DuraPlus chimney systems.
Choice: Choose a stove that is listed by a
recognized testing laboratory, is appropriate for
your needs, and is not larger than required.
Installation: Once the chimney system is in place,
install the stove and stovepipe as described in the
stove manufacturer’s instructions, maintaining all
required clearances.
Flues: Connect only one solid fuel appliance
per chimney. Oil-burning appliances are
restricted to one appliance per chimney, as
well.
Operation: Follow the stove manufacturer’s
instructions and safety manual for maximum
efciency and safety. Overring can damage
the stove and stovepipe.
Fuels: Do not burn driftwood, plastic, or
chemically treated wood such as railroad ties.
They are corrosive to your replace, stovepipe
and chimney. Follow the stove manufacturer’s
instructions and safety manual in regards to
fuels. Not all stoves are equipped to burn coal.
Coal with a low sulfur content will reduce the
possibility of corrosion.
Mobile Homes: Please read the stove
manufacturer’s instructions and safety manual
carefully. Not all stoves are listed for use in
mobile homes.
