Improper installation, adjustment, alteration, service, mainte- nance, or use can cause carbon monoxide poisoning, explo- sion, fire, electrical shock, or other conditions which may cause personal injury, loss of life, or property damage. Consult a qualified installer, service agency, local gas sup- plier, or your distributor or branch for information or assis- tance. The qualified installer or agency must use only
For accessory installation details, refer to the applicable installa- tion literature.
NOTE: Remove all shipping brackets and materials before oper- ating the furnace.
Step 1ÐLocation
GENERAL
Do not install furnace in a corrosive or contaminated atmo- sphere. Make sure all combustion and circulating air require- ments are followed, in addition to all local codes and ordinances.
Do not use this furnace during construction when adhesives, sealers, and/or new carpets are being installed. If the furnace is required during construction, use clean outside air for combustion and ventilation. Compounds of chlorine and fluorine when burned with combustion air form acids which cause corrosion of the heat exchangers and metal vent system. Some of these compounds are found in paneling and dry wall adhesives, paints, thinners, masonry cleaning materials, and many other solvents commonly used in the construction process.
Excessive exposure to contaminated combustion air will result in safety and performance related problems.
Do not install the furnace on its back; safety control operation will be adversely affected. Failure to follow this warning could result in fire, personal injury, or death.
This furnace must be installed so the electrical components are protected from water.
Locate the furnace as close to the chimney/vent and as near the center of the air distribution system as possible. The furnace should be installed as level as possible.
Provide ample space for servicing and cleaning. Always comply with the minimum fire protection clearances shown on the unit rating plate. This furnace shall not be installed directly on carpeting, tile, or any combustible material other than wood flooring. The furnace may be installed on combustible flooring when installed with the accessory downflow subbase, which is available from your distributor or branch when required.
LOCATION RELATIVE TO COOLING EQUIPMENT Ð The cooling coil must be installed parallel with or on the downstream side of the furnace to avoid condensation in the heat exchangers. When installed parallel with a furnace, dampers or other means used to control the flow of air must prevent chilled air from entering the unit. If the dampers are manually operated, they must be equipped with means to prevent operation of either unit unless the damper is in the
HAZARDOUS LOCATIONS
TO BURNERS
A93044
When furnace is installed in a residential garage, it must be installed so that burners and ignition sources are located a minimum of 18 in. above floor. The furnace must be located or protected to avoid physical damage by vehicles. When furnace is installed in a public garage, airplane hangar, or other building having a hazardous atmosphere, unit must be installed in accordance with requirements of National Fire Protection Association, Inc.
Step 2ÐAir For Combustion and Ventilation
Provisions for adequate combustion and ventilation air must be provided in accordance with Section 5.3 of the NFGC, Air for Combustion and Ventilation, or applicable provisions of the local building codes.
Canadian installations must be installed in accordance with NSC- NGPIC and all authorities having jurisdiction.
Air for combustion must not be contaminated by halogen compounds, which include fluoride, chloride, bromide, and iodide. These elements are found in aerosol sprays, deter- gents, bleaches, cleaning solvents, salts, air fresheners, and other household products.
