GENERAL INSTRUCTIONS
Combustion Air Quality
CAUTION:
Combustion air must not be drawn from a
corrosive atmosphere.
To maximize heat exchanger life, the combustion air
must be free of chemicals that can form corrosive acidic
compounds in the combustion gases. The recommended
source of combustion air is to use outdoor air. However,
the use of indoor air in most applications is acceptable
except as listed:
• If the furnace is installed as a single pipe installation
in a confi ned space, it is required that the necessary
combustion air come from the outdoors by way of attic,
crawl space, air duct, or direct opening. For Installations
in confi ned spaces, see pages 8 - 10 for combustion
air requirements.
• Installations in these locations may require outdoor air
for combustion, due to chemical exposures:
Commercial buildings
Buildings with indoor pools
Furnaces installed in laundry rooms
Furnaces installed in hobby or craft rooms
Furnaces installed near chemical storage areas
• Exposure to the following substances in the combustion
air supply may require outdoor air for combustion:
Permanent wave solutions
Chlorinated waxes and cleaners
Chlorine based swimming pool chemicals
Water softening chemicals
De-icing salts or chemicals
Carbon Tetrachloride
Halogen type refrigerants
Cleaning solvents (perchloroethylene)
Printing inks, paint removers, varnishes, etc.
Hydrochloric Acid
Cements and glues
Antistatic fabric softeners
Masonry acid washing materials
Operation of Furnace During Construction
CAUTION:
Failure to follow these instructions will void the
factory warranty and may signifi cantly reduce
the life or the performance of the furnace,
and/or result in other unsafe conditions. It is
the responsibility of the installing contractor
to insure these provisions are met.
