CHIMNEY CONNECTOR
Your chimney connector and chimney must
have the same diameter as the furnace outlet. If
this is not the case, we recommend you contact
your dealer in order to insure there will be no
problem with the draft.
The furnace pipe must be made of aluminized
or cold roll steel with a minimum thickness of
0.021” or 0.53 mm. It is strictly forbidden to use
galvanized steel.
Your connector should be assembled in such a
way that the male section (crimped end) of the
pipe faces down. Attach each of the sections to
one another with three equidistant metal screws.
Seal the joints with furnace cement.
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 insure 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.
