GENERAL INFORMATION
TheR8GESinglePackageGasHeating/ElectricCooling
Unit is designed only for outdoor rooftop or ground level
installations and can be readily connected to the high
static duct system of a home. This unit has been tested
for capacity and efciency in accordance with A.R.I.
Standards and will provide many years of safe and
dependable comfort, providing it is properly installed
and maintained. With regular maintenance, this unit will
operate satisfactorily year after year. Abuse, improper
use, and/or improper maintenance can shorten the life
of the appliance and create unsafe hazards.
To achieve optimum performance and minimize equipment
failure, it is recommended that periodic maintenance be
performed on this unit. The ability to properly perform
maintenance on this equipment requires certain tools
and mechanical skills.
√ The cooling load of the area to be conditioned must be
calculated and a system of the proper capacity selected.
It is recommended that the area to be conditioned be
completely insulated and vapor sealed.
√ Check the electrical supply and verify the power supply
is adequate for unit operation. Consideration should be
given to availability of electric power, service access,
noise, and shade. If there is any question concerning
the power supply, contact the local power company.
√ All units are securely packed at the time of shipment and
upon arrival should be carefully inspected for damage
prior to installing the equipment at the job site. Verify
coil fins are straight. Claims for damage (apparent or
concealed) should be filed immediately with the carrier.
√ Survey the job site to determine the best location for
mounting the outdoor unit. Choose an appropriate
location that minimizes the length of the supply and
return air ducts.
√ Please consult your dealer for maintenance information
and availability of maintenance contracts. Please read
all instructions before installing the unit.

slab, slightly above the grade level, and parallel to the
home. DO NOT PLACE UNIT UNDER THE HOME.
• Overhead obstructions, poorly ventilated areas, and
areas subject to accumulation of debris should be
avoided. Do not place the unit in a confined space or
recessed area where discharge air from the unit to re-
circulate into the condenser air inlet, through the coil.

This unit should be sized to provide the design heating
load requirement. Heating load estimates can be made
using approved methods available from Air Conditioning
Contractors of America (Manual J); American Society of
Heating,Refrigerating,andAirConditioningEngineers;
or other approved engineering methods. For installations
above 2,000 ft., the unit should have a sea level input
rating large enough that it will meet the heating load after
deration for altitude.
COMbUSTION AIR REQUIREMENTS
WARNING:
Provisions must be made during the installation of this
unit that provide an adequate supply of air for combustion.
• Instructions for determining the adequacy of an
installation can be found in the current revision of the
NFGC(ANSIZ223.1/NFPA54).
. These requirements are for
USinstallationsasfoundintheNFGC.
• TherequirementsinCanada(B149.1)arestructured
differently. Consult with B149.1 and local code officials
for Canadian installations.
Air openings in the door of the unit, warm air registers, and
return air grilles must never be restricted. If the unit does
not receive an adequate supply of air for combustion, the
flame roll-out control located above the burners will open,
turning off the gas supply to the burners. This safety device
is a manually reset switch. IMPORTANT NOTE: DO NOT
.
If this control must be replaced, use only factory authorized
