!
CARBON MONOXIDE POISONING AND UNIT
DAMAGE HAZARD
Failure to follow this warning could result in personal
injury or death, and unit component damage.
Corrosive or contaminated air may cause failure of parts
containing flue gas, which could leak into the living
space. Air for combustion must not be contaminated by
halogen compounds, which include fluoride, chloride,
bromide, and iodide. These elements can corrode heat
exchangers and shorten furnace life. Air contaminants
are found in aerosol sprays, detergents, bleaches,
cleaning solvents, salts, air fresheners, and other
household products. Do not install furnace in a corrosive
or contaminated atmosphere. Make sure all combustion
and circulating air requirements are met, in addition to
all local codes and ordinances.

All fuel−burning equipment must be supplied with air for fuel
combustion. Sufficient air must be provided to avoid negative
pressure in the equipment room or space. A positive seal
must be made between the furnace cabinet and the
return−air duct to prevent pulling air from the burner area and
from draft safeguard opening.
