CONNECTION TO A METAL PRE-FABRICATED CHIMNEY
When a metal prefabricated chimney is used,
the manufacturer’s installation instructions
must be followed precisely. 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 the proper
clearance to the structure as recommended by
the manufacturer. This clearance is usually a
minimum of 2” (51mm), although it may vary by
manufacturer or for certain components.
There are basically two methods of metal
chimney installation. One method is to install
the chimney inside the residence through the
ceiling and the roof (Figure 13A). I nstall an
attic insulation shield to maintain the specified
clearance to insulation. Insulation in this air
space will cause a heat buildup which may ignite
the ceiling joists. The other method is to install
an exterior chimney that runs up the outside
of the residence (Figure 13B). This method
of installation requires at a minimum a wall
pass-through device, a wall support package,
insulated “T” section and roof flashing. The
components illustrated may not look exactly like
the system you purchase, but they demonstrate
the basic components you will need for a
proper and safe installation.

FIGURE 13A - INTERIOR CHIMNEY
The chimney must be the required height
above the roof or other obstruction for safety
and proper draft operation. The chimney
must be a minimum of 3’ (91cm) higher than
the highest point where it passes through the
roof, and at least 2’ (61cm) higher than the
highest part of the roof or structure that is
within 10’ (305cm) of the chimney, measured
horizontally (2-10-3 Rule Figure on page
9).
FIGURE 13B - EXTERIOR CHIMNEY
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 CHIMNEYS.
