by a qualified service technician.
S DO: Inspect your filter monthly and clean or replace when
needed.
S DO: Provide adequate airflow to the furnace for efficient
combustion and safe ventilation.
S DO: Keep your furnace free and clear of combustible
material.
S 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.
S DO NOT: Keep combustible materials, gasoline, and other
flammable liquids or vapors around your furnace.
S DO NOT: Cover your furnace in any manner.
S DO NOT: Store anything (including trash or debris) near your
furnace.

S DO NOT: In any way block or restrict airflow to your supply air
and return air grills.
S DO NOT: Use your furnace room as a broom closet or a place
to store any kind of chemical or cleaner.
S DO NOT: Contaminate the air used for combustion of your
furnace with any kind of chemical or fumes. This could also
cause heat exchangers 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 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.
! WARNING
FIRE OR EXPLOSION HAZARD
Failure to follow warnings could result in personal injury,
death, or property damage.
Keep insulation and combustible materials clear of furnace
and maintain clearances shown on unit clearance label.
Do not keep combustible materials, gasoline, and other
flammable liquids or vapors around your furnace.
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.
S Your new gas furnace may have been installed in one of two
ways, as a direct−vent (2−pipe, Figure 2) application or as a
non−direct−vent (1−pipe, Figure 3) application.
