The clearance (air space) between the outer chimney wall, and the inside of the Support Box, Firestop Radiation Shields, and Close Clearance Shields, in the cases of 7 and 8-inch diameter chimney will be less than 2 inches. Both of these systems have been extensively tested and evaluated at these clearances. This reduced clearance is permissible at these internal locations only. All other areas require a 2-inch minimum clearance. Never fill any required clearance space with insulation or any other materials. Combustible materials include lumber plywood, sheetrock, plaster and lath, furniture, curtains, electrical wiring and building insulation. Keep single wall stovepipe at least 18 inches  \naway from combustible materials, unless a clearance reduction system that is acceptable to the authority having jurisdiction is used, orthe appliance to be installed is listed and the instructions specify a different clearance.  \nPERMITS  \nContact your local Building Official or Fire Official regarding permits, restrictions, and installation inspections in your area.  \nDURAPLUS APPLICATIONS  \nUse DuraPlus with wood stoves, fireplaces, furnaces, boilers, water heaters, stoves, ranges, or other residential-type appliances fueled by oil, gas, coal, or wood.
