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 manufac-
turer. The chimney must be the required height above the roof or other obstructions for safety and proper draft operation.
