condensation and creosote formation, and
enhance draft. Include an access door by the
Tee Cap for chimney cleaning
(Refer to Fig

APPLIANCE RECOMMENDATIONS
Follow the appliance manufacturer’s
instructions. The requirements stated
below pertain to all 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 appliance and stovepipe
(if applicable) 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 and safety manual
for maximum efficiency and safety. Overfiring
can damage the appliance, stovepipe and
chimney, and can void your warrenties.
Fuels:
Do not burn driftwood, plastic, or
chemically treated wood such as railroad
ties. They are corrosive to your appliance
and chimney system. 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.

Multi-Story:
Consult local building code
officials for requirements in your area. 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 storey 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
