given. If these suggestions don’t eliminate your problem, call your
servicing contractor. Do not attempt to service this unit yourself!
• 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 mechanical skills and tools. Please consult your
dealer for maintenance information and availability of maintenance
contracts.
• Do not block or obstruct air openings on the unit or air openings
supplying the area where it is installed.
• Do not use this unit if any part has been under water. A flood-
damaged unit is extremely dangerous. Attempts to use the unit
can result in fire or explosion. A qualified service agency should

furnace if deemed necessary.
TGRG Gas / Electric Models
• The area around the gas heating / electric cooling unit and the
vicinity 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.
• For areas around the units gas heating section, precautions should
be taken to prevent blockage of the flue exhaust and combustion
air louvers from large amounts accumulating snow.
• Do not use the area around the unit as a storage area. This area must
be kept clean and 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.
• 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. If the
gas supply to the unit must be shut off, refer to the gas valve label
(Figure 2, page 5).
Combustion Air Supply
WARNING:
Combustion air must not be drawn from a corrosive
atmosphere.
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 attempt to reset this device yourself!
Call your servicing contractor.
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 flammable 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
