The Heat-Fab Saf-T Liner system is intended for use in conjunction with any residential building, heating appliance burning gas, liquid or solid fuels, such as a woodstove, fireplace insert, or an oil or gas fired central heating furnace, vented through masonry chimneys only. These heating appliances may not exceed the maximum continuous flue-gas outlet temperatures of 1000OF or cause condensation of corrosive acids on the liner, or create positive pressures in the chimney system.
CLEARANCE FROM COMBUSTIBLES Air space clearances between the masonry chimney exterior and combustible materials should be checked to verify that the chimney is in accordance with the following clearance specifications (Fig. 2). The minimum air space clearance between masonry chimneys and combustible materials shall be at least 1" for a UL Listed Installation. Insulation Combustible framing member or wall DETERMINING THE LINER DIAMETER The Saf-T Liner must be properly sized for your heating appliance.
DETERMINE THE NUMBER OF LINER SECTIONS Saf-T Liner is available in 12", 18", 24", 36" and 48" fixed lengths and telescoping sections. NOTE: Two is the maximum number of telescoping lengths which may be installed above the appliance tee. A telescoping section between the appliance and clean out tee will allow for both radial and vertical adjustments during the installation.
OPENING THE CHIMNEY NOTE: Wear eye protection and dust respirator. An opening for the liner system will have to made for any existing chimney without an opening. If there is an opening, it may need to be expanded in order to insert the tee take off into the removable tee or accomodate the support system chosen.
CLOSING THE CHIMNEY OPENING Non-Fireplace Chimney Before closing the opening in the chimney, make certain that the Saf-T Wrap is positioned securely around the applaince tee. Several brick halves and mortar will be needed to close in around the take off. Rebuild the chimney using brick as square as possible. Fill mortar in tightly around the take off. Make sure that the starter section fits smoothly into the takeoff before the mortar cures.
Rain Cap CHIMNEY MAINTENANCE The chimney connector and Saf-T Liner should be inspected frequently during the heating season and cleaned annually (more often if necessary) by a professional, certified chimney sweep. Formation of creosote and soot and the need for removal occurs when wood is burned slowly, producing tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool flue of a slow burning fire.
ATTENTION HOMEOWNER FOLLOW THESE CHIMNEY MAINTENANCE INSTRUCTIONS: The chimney connector and Saf-T Liner should be inspected frequently during the heating season and cleaned annually (more often if necessary) by a professional, certified chimney sweep. The chimney should be inspected at least every 6 to 8 weeks during the heating season and once prior to the season to determine if (1) a creosote or soot buildup has occured or (2) if some other mechanism has caused a failure of the liner system.
