•Air filters must be installed in the system and must be maintained during construction.
•Air filters must be replaced upon construction completion.
•The input rate and temperature rise must be set per the furnace rating plate.
•One hundred percent (100%) outdoor air must be provided for combustion air requirements during construction. Temporary ducting may supply outdoor air to the furnace. Do not connect duct directly to the furnace. Size the temporary duct following the instructions in section for Combustion, Dilution and Ventilation Air in a confined space with air from outside.
•The furnace heat exchanger, components, duct system, air filters and evaporator coils must be thoroughly cleaned following final construction cleanup.
•All furnace operating conditions (including ignition, input rate, temperature rise and venting) must be verified according to these installation instructions.
General
These instructions are intended as a general guide and do not supersede local codes in any way. Consult authorities having jurisdiction before installation.
In addition to the requirements outlined previously, the following general recommendations must be considered when installing one of these furnaces:
•Place the furnace as close to the center of the air distribution system as possible. The furnace should also be located close to the chimney or vent termination point.
•When the furnace is installed in
•When the furnace is installed in
•When the furnace is installed in an attic or other insulated space, keep insulation away from the furnace.
•When the furnace is installed in an unconditioned space, consider provisions required to prevent freezing of condensate drain system.
CAUTION
These units should not be installed in areas normally subject to freezing temperatures.
WARNING
Product Contains Fiberglass Wool.
Disturbing the insulation in this product during installation, maintenance, or repair will expose you to fiberglass wool. Breathing this may cause lung cancer. (Fiberglass wool is known to the State of California to cause cancer.)
Fiberglass wool may also cause respiratory, skin, and eye irritation.
To reduce exposure to this substance or for further information, consult material safety data sheets available from address shown below, or contact your supervisor.

WARNING
Insufficient combustion air can cause headaches, nausea, dizziness or asphyxiation. It will also cause excess water in the heat exchanger resulting in rusting and premature heat exchanger failure. Excessive exposure to contaminated combustion air will result in safety and performance related problems. Avoid exposure to the following substances in the combustion air supply:
Permanent wave solutions
Chlorinated waxes and cleaners
Chlorine base swimming pool chemicals
Water softening chemicals
Carbon tetrachloride
Halogen type refrigerants
Cleaning solvents (such as perchloroethylene)
Printing inks, paint removers, varnishes, etc.
Hydrochloric acid
Antistatic fabric softeners for clothes dryers
Masonry acid washing materials
In the past, there was no problem in bringing in sufficient outdoor air for combustion. Infiltration provided all the air that was needed. In today’s homes, tight construction practices make it necessary to bring in air from outside for combustion. Take into account that exhaust fans, appliance vents, chimneys, and fireplaces force additional air that could be used for combustion out of the house. Unless outside
