CONDENSING GAS FURNACE: OWNER'S MANUAL
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in intermittent unit operation.
For proper and safe operation the furnace needs air for combustion and
ventilation. Do not block or obstruct air openings on the furnace, air
opening to the area in which the furnace is installed, and the space
around the furnace
In addition to the safety rules above, make sure that the following In
addition to the safety rules above, make sure that the following
combustion-air requirements are met for non-direct vent aplications:
• Combustion air must be clean and uncontaminated with chlorine or
fluorine. These compounds are present in many products around the
home, such as: water softener salts, laundry bleaches, detergents,
adhesives, paints, varnishes, paint strippers, waxes, and plastics.
• Make sure the combustion air for your furnace does not contain any of
these compounds. During remodeling be sure the combustion air is
fresh and uncontaminated. If these compounds are burned in your
furnace, the heat exchangers may deteriorate.
• A furnace installed in an attic or other insulated space must be kept
free and clear of insulating material. Examine the furnace area when
the furnace is installed or when insulation is added. Some insulation
materials may be combustible.
• Should the gas supply fail to shut off or if overheating occurs, shut off
the gas valve to the furnace before shutting off electrical supply.
This furnace contains SAFETY DEVICES which must be MANUALLY
RESET. If the furnace is left unattended for an extended period of time,
have it checked periodically for proper operation. This precaution will
prevent problems associated with no heat, such as frozen water pipes,
etc. See "Before You Request a Service Call" section in this manual.
BEFORE STARTING YOUR FURNACE
Examine the furnace installation to determine that:
1. All flue gas carrying areas external to the furnace (i.e. chimney,
vent connector) are clear and free of obstructions.
2. The vent connector is in place, slopes upward and is physically
sound without holes or gaps.
3. The return-air duct connection(s) is physically sound, is sealed to
the furnace casing, and terminates outside the space containing the
furnace.
4. The physical support of the furnace is sound without sagging
cracks, gaps, etc. around the base.
5. There are no obvious signs of deterioration of the furnace.
6. The
burner flames are in good adjustment (see
comparison with pictorial sketches or drawings of the main burner
flame).

FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in personal injury, death or
property damage.
Should the gas supply fail to shut off or if overheating occurs, turn off
the manual gas valve to the furnace BEFORE turning off the electrical
supply and install lockout tag.
Instead of a continuously burning pilot flame which wastes valuable
energy, your furnace uses an automatic, hot surface ignition system to
light the burners each time the thermostat signals the furnace to start.
Follow these important safeguards:
• Never attempt to manually light the burners with a match or other
• Read and follow the operating instructions on inside of main furnace
• If a suspected malfunction occurs with your gas control system, such
• CHECK AIR FILTER: Before attempting to start your furnace, be
