W415-1117 / A / 03.11.1417IOM8.0 NON-DIRECT VENT FURNACE INSTALLATIONSUSING INDOOR COMBUSTION AIR (ONE PIPESYSTEM)H13.0The furnace, although designed as a direct vent type appliance, may be installed with the intake vent inside thestructure.Adequate provisions for combustion and ventilation air must be in accordance with CAN/CGA-B149 in Canada,and ANSI Z223.1 - 1992, section 5.3, “Air for Combustion and Ventilation,” in the United States. Check withlocal authorities for any additional building codes bylaws or regulations.AIR FOR COMBUSTION AND VENTILATION PURPOSES MUST NOT ORIGINATE FROM ACORROSIVE ATMOSPHERE. ANY FURNACE FAILURE CAUSED BY CORROSIVE ELEMENTS ISEXCLUDED FROM WARRANTY COVERAGE.CAUTION !!The following types of installation sites (but not limited to the following) will REQUIRE OUTDOOR AIR forcombustion because of chemical exposures:• Commercial buildings• Buildings with indoor swimming pools• Furnaces installed in laundry rooms• Furnaces in hobby or craft rooms• Furnaces installed near chemical storage areasExposure to the following substances in the combustion air supply (but not limited to the following) will alsorequire OUTDOOR AIR for combustion:• Aerosols, particularly CFC based or propelled aerosols• Air fresheners• “Airplane Glue” and similar adhesives and cements• Ammonia, as commonly found in permanent wave solutions used in hair dressing salons• Anti-static fabric softeners used in clothes dryers• Carbon tetrachloride• Chlorinated cleaners and waxes• Chlorine and bromine based swimming pool chemicals• De-icing salts or chemicals (rock salt, etc.)• Dry cleaning fluids such as perchloroethylene• Fumes from curing polyurethane and similar substances• Halogen based refrigerants including R-12 and R-22• Hydrochloric acid, muriatic acid and other acid based masonry washing and curing materials• Printer’s inks, paint removers, varnishes, varsol, toluene, etc.• Water softener salt and chemicalsCombustion air must be free of acid forming chemicals such as sulphur, fluorine and chlorine. These elementsare found in aerosol sprays, detergents, bleaches, cleaning solvents, air fresheners, paint and varnishremovers, refrigerants, and many other commercial and household products. When burned in a gas flame,vapors from these products form acid compounds. Acid compounds increase the dew point temperature of theflue products and are highly corrosive after they condense.H3.11THIS FURNACE AND ANY OTHER FUEL BURNING APPLIANCE MUST BE PROVIDEDWITH ENOUGH FRESH AIR FOR PROPER COMBUSTION AND VENTILATION OF THEFLUE GASES. MOST HOMES WILL REQUIRE THAT OUTSIDE AIR BE BROUGHT TOTHE FURNACE AREA. FAILURE TO DO SO CAN CAUSE PERSONAL INJURY, OR DEATHFROM CARBON MONOXIDE POISONING.WARNING !!
