or air openings supplying the area where it is installed.
If the unit is operated with inadequate combustion air
supply, the fl ame roll-out control switch located above
the burners will open, turning off the gas supply to the
burners. The fl ame roll-out control is a manual reset
device. Do not attempt to reset this device yourself! Call
your servicing contractor.
WARNING:
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
compounds in the combustion gases.
IMPORTANT NOTE: Do not store any chemicals with
fl ammable or caustic vapors near the vent termination.
Some examples of these chemicals are:
• Gasoline/Kerosene
• Permanent wave solutions
• Chlorinated waxes and cleaners
• Chlorine based swimming pool chemicals
• Water softening chemicals
• De-icing salts or chemicals
• Carbon tetrachloride
• Halogen type refrigerants
• Cleaning solvents
• Cements, glues, paint removers, varnishes, etc.
• Hydrochloric acid
• Masonry acid washing materials
• Plumbing Stack
Ductwork
WARNING:
Failure to prevent products of combustion
from being circulated into the occupied space
can create potentially hazardous conditions
including carbon monoxide poisoning that
could result 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 fi replace insert, stove, etc. Doing so may result in fi re,
explosion, personal injury, carbon monoxide poisoning,
or property damage.

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 manufacturer’s User manual for
detailed programming instructions.
The thermostat should be mounted about 5 feet above the
fl oor on an inside wall and not on an outside wall or other
location where its operation may be adversely affected by
radiant heat from fi replaces, sunlight, or lighting fi xtures,
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.
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. A protective
timer circuit 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 (2 Stage)
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.
NOTE: On some units there is a factory set 3 minute
time delay between Stage 1 and Stage 2 heat when
Stage 2 heating is required. See Unit wiring diagram
label.
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.
NOTE: This unit is equipped with a manual-reset fl ame
roll-out limit switch. This switch acts to verify that the
burner fl ame is being drawn into the heat exchanger
tubes. If the fl ame is not being drawn into the tubes, the
fl ame roll-out switch will open within several seconds.
When this switch opens, the gas valve will de-energize
to stop the fl ow of gas. The combustion inducer will stay
energized and continue to operate until the thermostat is
satisfi ed or the switch is closed. Do not reset the fl ame
roll-out switch before identifying and correcting the fault
condition that caused the switch to open. If the switch
will not reset or continues to open, immediately contact
a qualifi ed serviceman to identify and repair the problem.
System Shutdown
Set the thermostat system mode to OFF and the thermostat
fan mode to AUTO. See Figure 1. NOTE: The system will
not operate, regardless of the thermostat temperature
selector’s setting.
Operating the Indoor Blower Continuously
Set the thermostat fan mode to ON (or CONT on some
thermostat models). See Figure 1.
The indoor blower will start immediately, and will run
continually until the fan switch is reset to AUTO.
The continuous indoor blower operation can be obtained
with the thermostat system switch set in any position,
including OFF.
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 fi replace operation.
SYSTEM MAINTENANCE
CAUTION:
Verify all electrical power to the unit is
disconnected and the gas is shut off before
performing the following recommended
maintenance.
Proper maintenance is most important to achieve the best
performance from the appliance and should be performed
by a qualifi ed service technician at least once a year.
Follow the maintenance schedule and the instructions
below for years of safe, trouble free operation.
• Do not place combustible materials on or against the
cabinet.

the aluminum fi ns.
• Check for and remove any obstructions such as twigs,
sticks, etc.
• Clean the blower compartment regularly during the
heating and cooling seasons to remove any dust
that may have accumulated in the compartment or on
the blower and motor. Buildup of dust on the blower
and motor can create excessive loads on the motor
resulting in higher than normal operating temperatures
and possible shortened service life.
Air Filters
WARNING:
Never operate the unit without a fi lter in the
return air system. Dust and lint in the return
air can build up on the internal components,
resulting in loss of effi ciency, equipment
damage, and possible fi re risk.
This unit is not supplied with air fi lter(s) and has no means
for accommodating internal air fi lter(s). The installer is
responsible for installing a fi ltration system into the return
air duct of this system. The fi lter(s) of this system should
be checked at monthly.
It is very important to replace or clean the fi lter(s) installed
in the return air duct of this system. A clogged fi lter could
cause airfl ow related problems and reduce the overall
effi ciency of your unit. Depending upon which type of fi lter
was installed with your unit, clean (permanent) or replace
(disposable) fi lter(s) of your system at the beginning of
every heating sea son, the beginning of every cooling
season, and when an accumulation of dust and dirt are
visible on the fi lter. IMPORTANT: Replace disposable
fi lter(s) installed in your system only with the same
size dimensional fi lters that are being replaced. Clean
permanent fi lter(s) as described by the manufacturer.
Motor Lubrication
The motors for the circulating air blower, outdoor fan, and
combustion blower are pre-lubricated and sealed by the
manufacturer. No further oiling is required for the life of
this product.
Burner Maintenance
CAUTION:
Some components in the burner vestibule are
at high temperatures while the burners are
operating. Use caution to avoid personal injury.
Check the burner fl ames at the start of every heating
season. Set the thermostat above the room temperature.
Remove the control access panel to the unit and visually
inspect the burner assembly to make sure that the fl ame
