WELCOME TO A NEW GENERATION OF COMFORT

Congratukttions! In light of rising energy costs, the 58MXA,

58MCA, 58MTA, and WeatherMaker Infinity, Multipoise, Gas-

Fired Condensing Furnaces are among the soundest investments

today's homeowner can make.

Your new furnace is truly a triumph of technology in home heat- ing. A revolutionary design employs 2 heat exchangers to "squeeze" out the maximum amount of heat from the fuel con- sumed. In fact, your new furnace is so efficient, over 90%* of the heat generated during combustion is captured and delivered inside your home. That is more than a 33%* increase in heating effi- ciency over conventional furnaces.

These are among the most enelgy-efficient furnaces you can buy to- day. They also are among the safest and most dependable. We are proud of the technological advances incolporated into the design of these funmces. With only minimal care, your new fulnace will deliver many years of money-saving home comfort and enjoyment. Spend

just a few minutes with this manual to learn the operation of your new

fulnace and the small amount of maintenance it takes to help keep it operating at peak efficiency ye_u after yeal;

FURNACE COMPONENTS

[_ Cornbnstion-air intake connection to ensure contami-

nant-fiee air (right or left side).

Burner sight glass for viewing burner flalne.

Burner assembly (inside). Operates with energy-saving inshot burners and hot surt_ce igniter for safe,

dependable heating.

Redundant gas valve. Safe and efficient. Features 1 gas control with 2 internal shutoff valves. Valve appearance

varies with furnace model.

Vent outlet. Uses PVC pipe to carry flue gas fiom the fnr- nace's combustion system (right or left side).

Inducer motor. Pulls hot flue gases through the heat ex- changers, maintaining negative pressure for added safety.

Blower access panel safety interlock switch.

Air filter and retainer.

Condensate &ain connection. Collects moisture con- densed fiom burned gases for disposal into holne drain

system. (Location in fnrnace varies.)

Heavy-duty blower. Circulates air across the heat ex- changers to transfer heat into the home.

Secondary condensing heat exchanger (inside). Wrings out more heat through condensation. Constructed with polypropylene-laminated steel to ensure durability.

Primary serpentine heat exchanger (inside). Stretches fuel dollars with the S-shaped heat-flow design. Solid con-

struction of corrosion-resistant aluminized steel means re- liability.

SAFETY CONSIDERATIONS

Recognize safety information. This is the safety-alert sym- bol z2x. When you see this symbol on the furnace and in

instrucfions 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 hazards which will result in severe

personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used

m identify unsafe practices which would result in minor per- sonal injury or product and prop-erty damage. NOTE is used to highlight suggestions which will result in enhanced instal-

lafion, reliability or operation. To minimize the possibility of serious personal injury, fire,

furnace damage, or improper operation; carefully follow

these safety rules:

• Your gas furnace uses air from outside the home for com-

bustion and vents flue gas to the outdoors. It is not to be installed using indoor air for combustion. 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 the furnace.

• Do not cover the furnace, store trash or debris near it, or in any way block the flow of fiesh air to the unit.

• A tunmce installed in an attic or other insulated space must be kept fiee and clear of insulating material. Examine the fur-

nace area when the funmce is installed or when insulation is added. Some materials may be combustible.

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.

Fire Hazard! Failure to keep insulation clear of

furnace could result in fire, personal injury/death

or property damage.

V!I gll-'1-'l [e]

Do not keep combustible materials, gasoline, and other flammable liquids or vapors around your

furnace. Failure to follow this warning could result

in fire, personal injury/death or property damage.

• Keep the area around your furnace clear and flee of COln- bustible materials, gasoline, and other flammable liquids and

vapors.

For proper and safe operation the furnace needs air for combustion and ventilation. Do not block

or obstruct the openings on the furnace, air openings to the area in which the furnace is in- stalled, and the space around the furnace. Failure to follow this warning could result in fire, personal injury/death or property damage.

BEFORE STARTING YOUR FURNACE

Examine the furnace installation to determine that:

1. All flue gas carrying areas external to the funmce (i.e. chimney, vent connector) are clear and tree of

obstruction s.

2. The vent connector is in place, slopes upward and is phys-

ically sound without holes or excessive corrosion.

3. The return-air duct connection(s) is physically sound, is sealed to the funmce casing, and terminates outside the

space containing the furnace.

4. The physical support of the funmce is sound without sag- ging 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).
