WARNING:
To avoid possible equipment damage, fire, or
death, the following instructions must be
observed regarding unit location, combustion
air requirements, and operation procedures.
Gas Heating/Electric CoolingUnit Location—The area
around the gas heating/electric cooling unit and the vicin-
ity of any other gas appliances must be kept clear and free
of combustible materials, gasoline, and other flammable
vapors and liquids. Do not store or use flammable items
such as paint, varnish, or strippers in the vicinity of the
unit.
Do not use the area around the unit as a storage area. This
area must be kept clear and clean. The unit must also be
kept clear of loose or exposed insulation materials. Examine
the unit's area when it is installed or when insulation is
added, since some insulation materials may be
combustible.
Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect
the unit and to replace any part of the control system and
any gas control which has been under water.
Familiarize yourself with the controls that shut off the gas
and electrical power to the unit. If the unit is to be shut
down for an extended period of time, turn off both the gas
and electrical power. For your safety always turn off both
the gas and electrical power before performing service or
maintenance on the furnace.
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 openings
supplying the area where it is installed.
If the unit is operated with inadequate combustion 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 factory
specified replacement part.
!
CAUTION:
Combustion air must not be drawn from a
corrosive atmosphere.
To maximize heat exchanger life, the combustion air must
be free of chemicals which form corrosive acidic com-
pounds in the combustion gases. Some examples of
these chemicals are chlorine, fluorine, and sulphur. Some
common sources of these chemicals are detergents,
bleaches, aerosol sprays, cleaning solvents, and a wide
variety of commercial and household products.
Ductwork—
!
WARNING:
Failure to prevent products of combustion from
being circulated into the occupied space can
create potentially hazardous conditions includ-
ing carbon monoxide poisoning that could re-
sult in personal injury or death.
The duct connections must be physically sound and
sealed to the unit's casing to prevent products of combustion
from entering the occupied space.
The return air and circulating air ductwork must not be
connected to any other heat producing device such as a
fireplace insert, stove, etc. Doing so may result in fire,
