Combustion Air Supply

The gas heating/electric cooling unit needs an
adequate supply of combustion and ventilation
air for proper and safe operation. Do not block
or obstruct air openings on the unit or air open-
ings supplying the area where it is installed.
If the unit is operated with inadequate combus-
tion air supply, the flame roll-out control switch
located above the burners will open, turning off
the gas supply to the burners. The flame roll-out
control is a manual-reset device. DO NOT
install a jumper wire across this switch to defeat
its function. DO NOT reset the control without
identifying and correcting the fault condition
which caused the control to trip. If this switch
must be replaced, use only the replacement
part specified in the accompanying Replace-
ment Parts List.
All air openings in the door of the unit, warm air
registers, and return air grilles must not be
restricted.
Combustion air must not be drawn
from a corrosive atmosphere.
To maximize heat exchanger life, the combus-
tion air must be free of chemicals which form
corrosive acidic compounds in the combustion
gases. Some examples of these chemicals are
chlorine, fluorine, and sulphur. Some common
Examine the
sources of these chemicals are detergents,
bleaches, aerosol sprays, cleaning solvents,
and a wide variety of commercial and household
products.
