SAFETY CONSIDERATIONS

FIRE, EXPLOSION, ELECTRICAL SHOCK, AND

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in dangerous

operation, personal injury, death, or property damage.
Improper installation, adjustment, alteration, service,

maintenance, or use can cause carbon monoxide poisoning,

explosion, fire, electrical shock, or other conditions which

may cause personal injury or property damage. Consult a

qualified service agency, local gas supplier, or your

distributor or branch for information or assistance. The

qualified service agency must use only factory--authorized

and listed kits or accessories when modifying this product.

WARNING

FIRE HAZARD

Failure to follow this warning could result in personal injury,

death, or property damage.
Solvents, cements and primers are combustible. Keep away

from heat, sparks and open flame. Use only in well--ventilated

areas. Avoid breathing in vapor or allowing contact with skin

or eyes.

WARNING

FURNACE RELIABILITY HAZARD

Failure to follow this caution may result in unit component

damage.
Application of this furnace should be indoors with special

attention given to vent sizing and material, gas input rate,

air temperature rise, unit leveling, and unit sizing.

CAUTION

Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock, or other

conditions which may cause death, personal injury, or property
damage. Consult a qualified installer, service agency, or your

distributor or branch for information or assistance. The qualified

installer or agency must use factory-authorized kits or accessories
when modifying this product. Refer to the individual instructions

packaged with the kits or accessories when installing.
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
performed by trained service personnel. When working on heating

equipment, observe precautions in literature, on tags, and on labels
attached to or shipped with furnace and other safety precautions

that may apply.
These instructions cover minimum requirements and conform to
existing national standards and safety codes. In some instances,

these instructions exceed certain local codes and ordinances,
especially those that may not have kept up with changing

residential construction practices. We require these instructions as a

minimum for a safe installation.
Follow all safety codes. Wear safety glasses, protective clothing,

and work gloves. Have a fire extinguisher available. Read these
instructions thoroughly and follow all warnings or cautions

included in literature and attached to the unit.

CUT HAZARD

Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care

and wear appropriate protective clothing, safety glasses and

gloves when handling parts, and servicing furnaces.

CAUTION

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 a hazard

which

could

result in personal injury or death.

CAUTION

is used

to identify hazards which

may

result in minor personal injury or

product and property damage.

NOTE

and

NOTICE

are used to

highlight suggestions which will result in enhanced installation,

reliability, or operation.

1. Use only with type of gas approved for this furnace. Refer

to the furnace rating plate.

2. Install this furnace only in a location and position as spe-

cified in the “Location” section of these instructions.

3. Provide adequate combustion and ventilation air to the fur-

nace space as specified in “Air for Combustion and Ventila-

tion” section.

4. Combustion products must be discharged outdoors. Con-

nect this furnace to an approved vent system only, as spe-
cified in the “Venting” section of these instructions.

5. Never test for gas leaks with an open flame. Use a commer-

cially available soap solution made specifically for the de-
tection of leaks to check all connections, as specified in the

“Gas Piping” section.

6. Always install furnace to operate within the furnace’s inten-

ded temperature--rise range with a duct system which has an

external static pressure within the allowable range, as spe-
cified in the “Start--Up, Adjustments, and Safety Check”

section. See furnace rating plate.

7. When a furnace is installed so that supply ducts carry air

circulated by the furnace to areas outside the space contain-

ing the furnace, the return air shall also be handled by
duct(s) sealed to the furnace casing and terminating outside

the space containing the furnace. See “Air Ducts” section.

8. A gas--fired furnace for installation in a residential garage

must be installed as specified in the warning box in the
“Location” section.

9. The furnace may be used for construction heat provided that

the furnace installation and operation complies with the first

CAUTION

in the

LOCATION

section of these instruc-

tions.

10. These Multipoise Gas--Fired Furnaces are CSA design--cer-

tified for use with natural and propane gases (see furnace

rating plate) and for installation in alcoves, attics, base-
ments, closets, utility rooms, crawlspaces, and garages. The

furnace is factory--shipped for use with natural gas. A CSA
(A.G.A. and C.G.A.) listed accessory gas conversion kit is

required to convert furnace for use with propane gas.

11. See Table 2 for required clearances to combustible con-

struction.

12. Maintain a 1--in. (25 mm) clearance from combustible ma-

terials to supply air ductwork for a distance of 36 in. (914

mm) horizontally from the furnace. See NFPA 90B or local
code for further requirements.
