IMPORTANT FACTS

Your furnace must have adequate

airﬂow for efﬁcient combustion and

safe ventilation. Do not enclose it in

an airtight room or “seal’’ it behind

solid doors. To minimize the possibil-

ity of serious personal injury, ﬁre,

damage to your furnace, or improper

operation,

carefully follow these

safety rules:

• Keep the area around your furnace

free of combustible materials, gasoline,

and other ﬂammable liquids and

vapors.

5

• Do not cover the furnace, store

trash or debris near it, or in any

way block the ﬂow of fresh air to

the unit.

• Combustion air must be clean and

uncontaminated with chlorine or ﬂuo-

rine. 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 air with vapors

of these compounds is burned in your

furnace, the heat exchangers and

metal vent system 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 in-

stalling the furnace or adding more

insulation. Some materials may be

combustible.

NOTE:

Do not use this furnace if any

part has been under water. Immedi-

ately call a qualiﬁed service technician

to inspect the furnace and to replace

any part of the control system, electri-

cal components and any gas control

which has been under water.

NOTE:

The qualiﬁed installer or

agency must use only factory-

authorized replacement parts, kits,

and accessories when servicing this

product.

This furnace contains safety devices

which must be manually reset. If the

furnace is left unattended for an ex-

tended period of time, have it

checked periodically for proper oper-

ation. 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.

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 and replacing air ﬁlters.

All other operations must be per-

formed by trained service personnel.

Observe safety precautions in this

manual, on tags and labels attached

to the furnace, and other safety pre-

cautions 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.
