When a metal prefabricated chimney is used, the manufac-
turer’s installation instructions must be followed precisely.
It will be necessary to install the ceiling support package
or wall pass through, “T” section package, firestops (when
needed), insulation shield, roof flashing, chimney cap, and
any other materials deemed necessary by the instructions
of manufacturer of the prefabricated chimney. Maintain
the proper clearance to the structure as recommended by
the manufacturer. This clearance is usually a minimum of
2 inch (51mm), although it may vary by manufacturer or for
certain components. Follow the manufacturers’ instructions
carefully.
There are basically two methods of metal chimney instal-
lation. One method is to install the chimney inside the
residence through the ceiling and the roof. Install an attic
insulation shield to maintain the specified clearance to insu-
lation. Insulation in this air space will cause a heat buildup
which may ignite the ceiling joists. This method of installa-
tion requires, at minimum, a ceiling support package, an
insulation shield and roof flashing.
Figure 14A.
The other method is to install an exterior chimney that runs
up the outside of the residence.
See Figure 14B.
The
components illustrated may not look exactly like the system
you purchase, but they demonstrate the basic components
necessary for a proper and safe installation.
The chimney must be the required height above the roof or
other obstruction for safety and for proper draft operation.
The requirement is that the chimney must be at least 3 ft.
(91cm) higher than the highest point where it passes through
the roof and at least 2 ft (61cm) higher than the highest part
of the roof or structure that is within 10 ft. (305cm) of the
chimney, measured horizontally.
(See page 9)
In Canada, when using a factory-built chimney,
make sure it is safety listed, Type UL 103 HT
CLASS "A" or conforming to CAN/ULC-S629,
STANDARD FOR 650°C FACTORY-BUILT CHIM-
NEYS.
