IMPORTANT SAFETY INFORMATION
Please read all information in this manual thoroughly
and become familiar with the capabilities and use of your
appliance before attempting to operate or maintain this
unit. Pay attention to all safety warnings and any other
special notes highlighted in the manual.
Safety markings are used frequently throughout this
manual to designate a degree or level of seriousness and
should not be ignored. WARNING indicates a potentially
hazardous situation that if not avoided, could result in
personal injury or death. CAUTION indicates a potentially
hazardous situation that if not avoided, may result in minor
or moderate injury or property damage.
WARNING:
To avoid possible equipment damage, fire, or
personal injury, the following instructions must
be observed regarding unit maintenance and
operational procedures.
• Under no circumstances should the appliance owner
attempt to install and/or service this equipment. Some
local codes require licensed installation / service
personnel for this type of equipment. Improper service,
adjustment, or maintenance may cause explosion, fire,
electrical shock or other hazardous conditions which
may result in personal injury or property damage.
• Keep this literature where you have easy access to it in
the future. If a problem occurs, check the instructions
and follow recommendations 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.
• 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.
• Do not use this furnace if any part has been under
water. A flood-damaged furnace is extremely dangerous.
Attempts to use the furnace can result in fire or explosion.
A qualified service agency should be contacted to
inspect the furnace and to replace all gas controls,
control system parts, electrical parts that have been
wet or the furnace if deemed necessary.
• Ne pas utiliser cet appareil de chauffage s’il a été en
partie immergé dans l’eau. Un appareil de chauffage
endommagé par une inondation est extrêmement
dangereux. S’il est utilisé, un incendie ou une explosion
peut se produire. Il faut avoir recours à une entreprise
d’entretien qualifiée pour faire inspecter l’appareil de
chauffage et remplacer toutes les commandes de gaz,
les pièces du système de contrôle, les pièces électriques
qui sont entrées en contact avec l’eau ou l’appareil de
chauffage lui-même, si cela est jugé nécessaire.
• 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
