The furnace, although designed as a direct vent type appliance, may be installed with the intake vent inside the
structure.
THIS FURNACE AND ANY OTHER FUEL BURNING APPLIANCE MUST BE PROVIDED
WITH ENOUGH FRESH AIR FOR PROPER COMBUSTION AND VENTILATION OF THE
FLUE GASES. MOST HOMES WILL REQUIRE THAT OUTSIDE AIR BE BROUGHT TO
THE FURNACE AREA. FAILURE TO DO SO CAN CAUSE PERSONAL INJURY, OR DEATH
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 with
local authorities for any additional building codes bylaws or regulations.
AIR FOR COMBUSTION AND VENTILATION PURPOSES MUST NOT ORIGINATE FROM A
CORROSIVE ATMOSPHERE. ANY FURNACE FAILURE CAUSED BY CORROSIVE ELEMENTS IS
The following types of installation sites (but not limited to the following) will REQUIRE OUTDOOR AIR for
combustion 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 areas
Exposure to the following substances in the combustion air supply (but not limited to the following) will also
require 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 fl uids 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 chemicals
Combustion air must be free of acid forming chemicals such as sulphur, fl uorine and chlorine. These elements
are found in aerosol sprays, detergents, bleaches, cleaning solvents, air fresheners, paint and varnish
removers, refrigerants, and many other commercial and household products. When burned in a gas fl ame,
vapors from these products form acid compounds. Acid compounds increase the dew point temperature of the
fl ue products and are highly corrosive after they condense.
