ABOUT THE GAS HEATING / ELECTRIC
COOLING UNIT
This gas heating unit with electric cooling has been designed
and built to 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. A regular
service and maintenance schedule should be established to
ensure efficient and safe operation of the unit. See System
Maintenance on page 5.
OPERATING INSTRUCTIONS
Thermostat styles vary. Some models may not include the AUTO
mode and others will have the AUTO in place of the HEAT
and COOL. Others may include all three. Please refer to the
thermostat’s User manual for detailed programming instructions.
The thermostat should be mounted about 5 feet above the floor
on an inside wall and not on an outside wall or other location
where its operation may be adversely affected by radiant heat
from fireplaces, sunlight, or lighting fixtures, and convective heat
from warm air registers or electrical appliances.
Cooling Operation (1 or 2 Stage Operation)
1. Set the thermostat system mode to COOL and the thermostat
fan mode to AUTO. See Figure 1.
2. Set the thermostat temperature selector to the desired
temperature level. The outdoor fan, compressor, and
indoor blower will all cycle on and off to maintain the indoor
temperature at the desired cooling level.
For 2-Stage Models Only: If Stage 1 cool does not satisfy the
thermostat demand, stage 2 cool will energize. The outdoor
compressor and indoor blower will ramp to high speed.
NOTE: If the temperature level is re-adjusted, or the system
mode is reset, the fan and compressor in the outdoor unit
may not start immediately. There may be a protective timer
circuit in the thermostat which holds the compressor and
the outdoor fan off for approximately 5 minutes following a
previous operation or the interruption of the main electrical
power.
Heating Operation (1 or 2 Stage Operation)
1. Set the thermostat system mode to Heat and the thermostat
fan mode to AUTO. See Figure 1.
2. Set the thermostat temperature selector to the desired
temperature level. The indoor blower and gas heat module
will cycle on and off to maintain the indoor temperature at
the desired heating level.
For 2-Stage Models Only:
If Stage 1 heat does not satisfy the
thermostat demand, stage 2 heat will energize. The inducer
motor and indoor blower will ramp to high speed.

WARNING:
If overheating occurs, or the gas supply fails to
shut off, shut off the gas valve to the unit before
shutting off the electrical supply.
System Shutdown
Set the thermostat system mode to OFF (see Figure 1) and
the thermostat fan mode to AUTO.
NOTE: The system will not
operate, regardless of the thermostat temperature selector’s
setting.
Continuous Indoor Blower Operation
The continuous indoor blower operation is typically used to
circulate the indoor air to equalize a temperature imbalance
due to a solar load, cooking, or fireplace operation.
Set the thermostat fan mode to ON (see Figure 1). The indoor
blower will start immediately and will run continually until the fan
switch is reset to AUTO. NOTE: On some thermostat models
the setting may be called CONT.
The continuous indoor blower operation can be obtained with
the thermostat system switch set in any position, including OFF.
