Installation
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. See below for chimney termination requirements.
