IMPORTANT FACTS
(DO’s and DO NOT’S)
•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.
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 factoryauthorized re-placement parts, kits,
and accessories when modifying or
repairing 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.

death. WARNING signifies hazards
which
could result in personal injury or
death. CAUTION is used to identify
unsafe practices which
minor personal injury or product and
property damage. NOTE is used to

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.
6. The pilot and burner flames are in
good adjustment (by comparison
with pictorial sketches or drawings
of the main burner flame and, if
applicable, the pilot burner flame).
