CONNECTION TO A METAL PREFABRICATED CHIMNEY
INSTALLATION
When a metal prefabricated chimney is used, the manufacturer’s installation instructions must be followed precisely. It will be necessary to install the ceiling support package or wall pass through, and “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", although it may vary by manufacturer or for certain components. Follow the manufacturers’ instructions carefully.
There are basically two methods of metal chimney installation. 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 insulation. Insulation in this air space will cause a heat buildup which may ignite the ceiling joists. This method of installation requires, at minimum, a ceiling support package, an insulation shield and roof flashing. See Figures 13 and 14.
The other method is to install an exterior chimney that runs up the outside of the residence. See Figures 15 and 16. (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' higher than the highest point where it passes through the roof and at least 2' higher than the highest part of the roof or structure that is within 10' of the chimney, measured horizontally.
