IMPORTANT FACTS (DO’S AND DON’TS)

S

DO: READ AND UNDERSTAND THIS MANUAL.

S

DO: Have your furnace and vent system inspected annually 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 insulating material.
Some materials may be combustible. Examine the furnace area
when the furnace is installed or when insulation is added.

S

DO NOT: Enclose your furnace in an airtight room or seal it
behind solid doors.

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 around 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, 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

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

SAFETY CONSIDERATIONS

Installing and servicing of 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 and replacing air 

filters

. All other operations must be per-

formed 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, CAUTION,
and NOTE. DANGER, WARNING, and CAUTION are used with
the safety

alert symbol. DANGER identifies the most serious haz-

ards 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 

may

 result in

minor personal injury or product and property damage. NOTE is used
to highlight suggestions which 

will

 result in enhanced installation, re-

liability, or operation.

To minimize the possibility of serious personal injury, 

fire

, damage to

your furnace, or improper operation, 

carefully follow these safety

rules 

which apply to both direct

vent and non

direct vent applica-

tions:

Your new gas furnace may have been installed in 1 of 2 ways, as a dir-
ect

vent (2

pipe

Figure 2) application or as a non

direct vent

(1

pipe

Figure 3) application.

In a direct

vent (2

pipe) application, your furnace uses air from out-

side the home for combustion and vents 

flue

 gas to the outdoors. This

type of application will have 2 pipes running from the furnace to the
outdoors. (See Fig. 2.) In this application, the vent and air

intake

pipes must terminate outside the structure and must not be obstructed
in any way. Do not block or obstruct air openings on furnace or spaces
around furnace.

In a non

direct vent (1

pipe) application, your furnace uses air from

adjacent to the furnace for combustion and vents 

flue

 gas to the out-
