WARNING

POSSIBLE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO FIRE, EXPLOSION, SMOKE, SOOT, CONDENSATION, ELECTRICAL SHOCK OR CARBON MONOXIDE MAY RESULT FROM IMPROPER INSTALLATION, REPAIR, OPERATION, OR MAINTENANCE OF THIS PRODUCT.

WARNING

TO PREVENT PERSONAL INJURY, PROPERTY DAMAGE OR DEATH DUE TO FIRE, DO NOT INSTALL THIS FURNACE IN A MOBILE HOME, TRAILER OR RECREATIONAL VEHICLE.

To ensure proper furnace operation, install, operate and maintain the furnace in accordance with these installation and operation instruc- tions, all local building codes and ordinances. In their absence, follow the latest edition of the National Fuel Gas Code (NFPA54/ANSI Z223.1), and/or CAN/CSA B149.1-05.1-05 Installation Codes, local plumbing or waste water codes, and other applicable codes.

The rated heating capacity of the furnace should be greater than or equal to the total heat loss of the area to be heated. The total heat loss should be calculated by an approved method or in accor- dance with “ASHRAE Guide” or “Manual J-Load Calculations” pub- lished by the Air Conditioning Contractors of America.

IV. LOCATION REQUIREMENTS & CONSIDERATIONS

WARNING

TO PREVENT POSSIBLE EQUIPMENT DAMAGE, PROPERTY DAMAGE, PERSONAL INJURY OR DEATH, THE FOLLOWING BULLET POINTS MUST BE OBSERVED WHEN INSTALLING THE UNIT.

Follow the instructions listed below when selecting a furnace loca- tion. Refer also to the guidelines provided in Combustion and Ventilation Air Requirements.

•Centrally locate the furnace with respect to the proposed or existing air distribution system.

•Ensure the temperature of the return air entering the furnace is between 55°F and 100°F when the furnace is heating.

•Provide provisions for venting combustion products outdoors through a proper venting system. Special consideration should be given to vent/flue pipe routing and combustion air intake pipe when applicable. Refer to Vent/Flue Pipe and Combustion Air Pipe -Termination Locations for appropriate termination locations and to determine if the piping system from furnace to termination can be accomplished within the guidelines given. NOTE: The length of flue and/or combustion air piping can be a limiting factor in the location of the furnace.

•Locate the furnace so condensate flows downwards to the drain. Do not locate the furnace or its condensate drainage system in any area subject to below freezing temperatures without proper freeze protection. Refer to Condensate Drain Lines and Trap for further details.

•Ensure adequate combustion air is available for the furnace. Improper or insufficient combustion air can expose building occupants to gas combustion products that could include carbon monoxide. Refer to Combustion and Ventilation Air Requirements.

•Set the furnace on a level floor to enable proper condensate drainage. If the floor becomes wet or damp at times, place the furnace above the floor on a concrete base sized approximately 1-1/2" larger than the base of the furnace. Refer to the Horizontal Applications and Considerations for leveling of horizontal furnaces.

•Ensure upflow or horizontal furnaces are not installed directly on carpeting, or any other combustible material. The only combustible material allowed is wood.

•A special accessory subbase must be used for upright counterflow unit installations over any combustible material (including wood). Refer to subbase instructions for installation details. (NOTE: A subbase will not be required if an air conditioning coil is located beneath the furnace between the supply air opening and the combustible floor.

•Exposure to contaminated combustion air will result in safety and performance-related problems. Do not install the furnace where the combustion air is exposed to the following substances:

chlorinated waxes or cleaners chlorine-based swimming pool chemicals water softening chemicals

deicing salts or chemicals carbon tetrachloride halogen type refrigerants

cleaning solutions (such as perchloroethylene) printing inks

paint removers varnishes hydrochloric acid cements and glues

antistatic fabric softeners for clothes dryers and masonry acid washing materials
