IMPORTANT FACTS (DO’S AND DON’TS)
DO: READ AND UNDERSTAND THIS MANUAL.
DO: Have your furnace and vent system inspected annually by a
qualified service technician.
DO: Inspect your filter monthly and clean or replace when
needed.
DO: Provide adequate airflow to the furnace for efficient
combustion and safe ventilation.
DO: Keep your furnace free and clear of insulating material.
Some materials may be combustible. Examine the furnace area
when the furnace is installed or when insulation is added.
DO NOT: Enclose your furnace in an airtight room or seal it
behind solid doors.
DO NOT: Keep combustible materials, gasoline, and other
flammable liquids or vapors around your furnace.
DO NOT: Cover your furnace in any manner.
DO NOT: Store anything (including trash or debris) near your
furnace.
DO NOT: In any way block or restrict airflow around your
furnace.
DO NOT: In any way block or restrict airflow to your supply air
and return air grills.
DO NOT: Use your furnace room as a broom closet or a place to
store any kind of chemical or cleaner.
DO NOT: Contaminate the air used for combustion of your
furnace with any kind of chemical or fumes. This could also
cause heat exchangers, metal vent systems or components to
deteriorate.
2
NOTE: These chemicals or fumes are present in many products
around the home, such as: water softener salts, any type of
household cleaning product, any type of laundry product,
adhesives, paints, varnishes, paint strippers, waxes and plastics, etc.
During remodeling be sure the combustion air is fresh and
uncontaminated. If these compounds are burned in your furnace,
the heat exchangers and metal vent system may deteriorate.
NOTE: The qualified installer or agency must use only
factory−authorized replacement parts, kits, and accessories when
modifying this product.
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 excessive corrosion.
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.
STARTING YOUR FURNACE
Your furnace uses an automatic, hot surface ignition system to light
the burners each time the thermostat signals the furnace to start.

SAFETY CONSIDERATIONS
Installing and servicing heating equipment can be hazardous due to
gas and electrical components. Only trained and qualified
personnel should install, repair, or service heating equipment.
Untrained personnel can perform basic maintenance functions such
as cleaning or replacing air filters. All other operations must be
performed by trained service personnel. Observe safety precautions
in this manual, on tags, and on labels attached to the furnace, and
other safety precautions that may apply.
Recognize safety information. This is the safety−alert symbol .
When you see this symbol on the furnace and in instructions or
manuals, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety−alert symbol.
DANGER identifies the most serious hazards which will result in
severe personal injury or death. WARNING signifies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices which would result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability or
operation.
Follow these important safeguards:
Never attempt to manually light the burners with a match
or other source of flame.
Fig. 2 − Do Not Light Burner with Match
Read and follow the operating instructions on inside of
main furnace door, especially the item that reads as
follows:
“Wait 5 minutes to clear out any gas. Then smell for gas,
including near the floor. If you smell gas, STOP!
Follow “B” in the safety information above on this
furnace label. If you don’t smell gas, go to the next step.”
If a suspected malfunction occurs with your gas control
system, such as the burners do not light when they
should, refer to the shutdown procedures on inside of
main furnace door, or in the “Shutting Down Your
Furnace” section and call your dealer as soon as possible.
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.
!
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, shut off the gas valve to the furnace BEFORE
shutting off the electrical supply and install lockout tag.
