INSTALLATION
The pipe must be short and straight. All sections installed
horizontally must slope at least 1/4 inch per foot, with
the upper end of the section toward the chimney. Any
installation with a horizontal run of furnace pipe must
conform to NFPA 211. You may contact NFPA (National
Fire Protection Association) and request the latest
edition of the NFPA Standard 211.
To ensure a good draft, the total length of the furnace
pipe should never exceed 8’ to 10’ (2.4m to 3.04 m).
(Except for cases of vertical installation, cathedral-roof
style where the smoke exhaust system can be much
longer and connected without problem to the chimney at
the ceiling of the room).
There should never be more than two 90 degrees elbows
in the smoke exhaust system.
Installation of a “barometric draft stabilizer” (fireplace
register) on a smoke exhaust system is prohibited.
Do not use with a flue damper. With a controlled
combustion wood furnaces the draft is regulated upon
intake of the combustion air in the furnace and not at the
exhaust.
FACTORY BUILT CHIMNEY
When a metal prefabricated chimney is used, the
manufacturer’s installation instructions must be
followed. You must also purchase (from the same
manufacturer) and install the ceiling support package
or wall pass-through and “T” section package, firestops
(where needed), insulation shield, roof flashing, chimney
cap, etc. Maintain proper clearance to the structure as
recommended by the manufacturer. The chimney must be
the required height above the roof or other obstructions
for safety and proper draft operation.
