CONNECTION TO A METAL PREFABRICATED CHIMNEY

When a metal prefabricated chim- ney is used, the manufacturer’s in- stallation instructions must be fol- lowed precisely. You must also pur- chase (from the same manufac- turer) 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 usu- ally a minimum of 2" (50mm), al- though 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 in- side the residence through the ceil- ing and the roof (Figure 15). The other method is to install an exterior chimney that runs up the outside of the residence (Figure 16). This method of installation requires at a minimum a wall pass-through de- vice, a wall support package, insu- lated “T” section and roof flashing. The components illustrated may not look exactly like the system you pur- chase, but they demonstrate the ba- sic components you will need for a proper and safe installation.

The chimney must be the required height above the roof or other ob- struction for safety and proper draft operation. The chimney must be a minimum of 3' (914mm) higher than the highest point where it passes through the roof, and at least 2' (610mm) higher than the highest part of the roof or structure that is within 10' (3048mm) of the chimney, measured horizontally (Figure 10).

REMEMBER: Follow the manu- facturer’s installation instructions and maintain the manufacturer’s specified clearance distances.
