CONNECTION TO A METAL PREFABRICATED CHIMNEY
When a metal prefabricated chimney is used, the manufac- turer’s installation instructions must be followed precisely. It will be necessary to install the ceiling support package or wall pass through, “T” section package, firestops (when needed), insulation shield, roof flashing, chimney cap, and any other materials deemed necessary by the instructions of manufacturer of the prefabricated chimney. Maintain the proper clearance to the structure as recommended by the manufacturer. This clearance is usually a minimum of 2 inch (51mm), although it may vary by manufacturer or for certain components. Follow the manufacturers’ instructions carefully.
There are basically two methods of metal chimney instal- lation. One method is to install the chimney inside the residence through the ceiling and the roof. Install an attic insulation shield to maintain the specified clearance to insu- lation. Insulation in this air space will cause a heat buildup which may ignite the ceiling joists. This method of installa- tion requires, at minimum, a ceiling support package, an insulation shield and roof flashing. Figure 14A.
The other method is to install an exterior chimney that runs up the outside of the residence. See Figure 14B. The components illustrated may not look exactly like the system you purchase, but they demonstrate the basic components necessary for a proper and safe installation.
The chimney must be the required height above the roof or other obstruction for safety and for proper draft operation. The requirement is that the chimney must be at least 3 ft. (91cm) higher than the highest point where it passes through the roof and at least 2 ft (61cm) higher than the highest part of the roof or structure that is within 10 ft. (305cm) of the chimney, measured horizontally. (See page 9)
IMPORTANT! FOLLOW MANUFACTUR- ERS’ INSTALLATION INSTRUCTIONS AND MAINTAIN CLEARANCES AS SPECIFIED ON PAGES 6 & 7.
