Fig. 4 - Multipoise Orientations

LOCATION

GENERAL

This multipoise furnace is shipped in packaged configuration. Some assembly and modifications are required when used in any of the four applications shown in Fig. 4.

NOTE: For high-altitude installations, the high-altitude conversion kit MUST be installed at or above 5500 ft above sea level. Obtain high-altitude conversion kit from your area authorized distributor.

This furnace must:

Sbe installed so the electrical components are protected from water.

Snot be installed directly on any combustible material other than wood flooring (refer to SAFETY CONSIDERATIONS).

Sbe located close to the chimney or vent and attached to an air distribution system. Refer to Air Ducts section.

Sbe provided ample space for servicing and cleaning. Always comply with minimum fire protection clearances shown on the furnace clearance to combustible construction label.

!WARNING

CARBON MONOXIDE POISONING AND UNIT DAMAGE HAZARD

Failure to follow this warning could result in personal injury or death, and furnace damage.

Corrosive or contaminated air may cause failure of parts containing flue gas, which could leak into the living space. Air for combustion must not be contaminated by halogen compounds, which include fluoride, chloride, bromide, and iodide. These elements can corrode heat exchangers and shorten furnace life. Air contaminants are found in aerosol sprays, detergents, bleaches, cleaning solvents, salts, air fresheners, and other household products. Do not install furnace in a corrosive or contaminated atmosphere. Make sure all combustion and circulating air requirements are met, in addition to all local codes and ordinances.

The following types of furnace installations may require OUTDOOR AIR for combustion due to chemical exposures:

SCommercial buildings

SBuildings with indoor pools S Laundry rooms

S Hobby or craft rooms, and S Chemical storage areas

If air is exposed to the following substances, it should not be used

for combustion air, and outdoor air may be required for combustion:

SPermanent wave solutions

SChlorinated waxes and cleaners

SChlorine based swimming pool chemicals S Water softening chemicals

S De-icing salts or chemicals S Carbon tetrachloride

S Halogen type refrigerants

S Cleaning solvents (such as perchloroethylene) S Printing inks, paint removers, varnishes, etc. S Hydrochloric acid

S Cements and glues

S Antistatic fabric softeners for clothes dryers S Masonry acid washing materials

All fuel-burning equipment must be supplied with air for fuel combustion. Sufficient air must be provided to avoid negative pressure in the equipment room or space. A positive seal must be made between the furnace cabinet and the return-air duct to prevent pulling air from the burner area and from draft safeguard opening.
