condensation and creosote formation, and

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 efciency and safety. Overring 
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.  
STEP-BY-STEP DIRECTIONS 
There are three general types of DuraTech 
Chimney installations: 
1.  Ceiling-supported. 
2. Tee-supported (through-the-wall) 
3. Masonry Fireplace 
Review the step-by-step directions before

Multi-Story:  Consult local building code 
ofcials for requirements in your area. 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 
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 
re resistance rating equal to or greater than 
that of the oor 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
