Page 15Cumberland Gap Wood StoveRSeptember 1, 2008 7006-188EWhen a metal prefabricated chimney is used, the manufacturer’s installation instructions must be followed precisely. It will benecessary to install the ceiling support package or wall pass through, “T” section package, firestops (when needed), insulationshield, roof flashing, chimney cap, and any other materials deemed necessary by the prefabricated chimney manuafacturers'instructions. Maintain the proper clearance to the structure as recommended by the chimney manufacturer. This clearanceis usually a minimum of 2" (51mm), although it may vary by manufacturer or for certain components. Follow the chimenymanufacturers’ instructions carefully.There are basically two methods of metal chimney installation. One method is to install the chimney inside the residence throughthe ceiling and the roof. Install an attic insulation shield to maintain the specified clearance to insulation. Insulation in this air spacewill cause a heat buildup which may ignite the ceiling joists. This method of installation requires, at minimum, a ceiling supportpackage, an insulation shield and roof flashing. See Figure 15A.The other method is to install an exterior chimney that runs up the outside of the residence. See Figure 15B. The componentsillustrated may not look exactly like the system you purchase, but they demonstrate the basic components necessary for a properand safe installation.The chimney must be the required height above the roof or other obstruction for safety and for proper draft operation. The require-ment 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 2ft. (61cm) higher than the highest part of the roof or structure that is within 10 ft. (305cm) of the chimney, measured horizontally.(See page 11)In Canada, when using a factory-built chimney, make sure it is safety listed, Type UL 103 HT CLASS "A"or conforming to CAN/ULC-S629, STANDARD FOR 650°C FACTORY-BUILT CHIMNEYS.CONNECTION TO A METAL PREFABRICATED CHIMNEYIMPORTANT!
