CHIMNEY PLACEMENT
When deciding the location of your chimney,
try to avoid modifications to roof beams and
other structural components of the building.
CHIMNEY ENCLOSURE REQUIRE-
MENTS
Through Rooms: Interior chimneys shall be
enclosed where they extend through closets,
storage areas, occupied spaces, or anyplace
where the surface of the chimney could be
contacted by persons or combustible materials.
Maintain at least a 2-inch air space between
the outer wall of the chimney and the enclosure
(Fig 2).
Multi-Story: Consult local building codes for
requirements in your area. In the U.S., the
National Fire Protection Association Standard
#211 states: “Factory-built chimneys that
pass through floors of buildings requiring the
protection of vertical openings shall be enclosed
with approved walls having a fire resistance
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.” In Canada,
except in single-family and two-family dwellings,
chimneys which extend through another story
must have an enclosure with a fire resistance
rating equal to or greater than that of the floor or
roof assembly through which they pass.
Cold Climates: In cold climates, chimneys
mounted on an outside wall should be
enclosed in a chase. Exterior chases reduce
condensation and creosote formation, and
enhance draft. Include an access door by the
Tee Cap for chimney cleaning (Refer to Fig 23).
STOVE RECOMMENDATIONS
Follow the stove manufacturer’s instructions.
The requirements stated below pertain to
all stoves or other appliances installed with
DuraTech Chimney systems.
Choice: Choose an appliance 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 stovepipe to connect the
appliance to the chimney as described in the
appliance manufacturer’s instructions. Be sure
to maintain all required clearances.
Flues: Connect only one solid fuel appliance
per chimney.
Operation: Follow the appliance
manufacturer’s instructions for maximum
efficiency and safety. Overfiring can damage
the appliance, stovepipe and chimney.
Fuels: Do not burn driftwood, plastic, or
chemically treated wood such as railroad
ties. They are corrosive to your appliance,
stovepipe and chimney. Follow the appliance
manufacturer’s instructions and safety manual
in regards to fuels. Not all appliances are
equipped to burn coal. Coal with a low sulfur
content will reduce the possibility of corrosion.
Mobile Homes: Please read the appliance
manufacturer’s instructions and safety manual
carefully. Not all appliances are listed for use
in mobile homes.
