IV. LOCATION REQUIREMENTS & CONSIDERATIONS
GENERAL
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
•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
•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
