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.
