WELCOME TO A NEW GENERATION OF COMFORT

Congratulations! In light of rising energy costs, the Infinity ICS Gas--Fired, Modulating Condensing Furnace is among the wisest investment today’s homeowner can make.

Your new furnace is truly a triumph of technology in home heating. A revolutionary design employs two heat exchangers to maximize the amount of heat from the fuel consumed. In fact, your new furnace is so efficient, up to 95%* of the heat generated during combustion is captured and delivered inside your home. That is more than a 33%* increase in heating efficiency over conventional furnaces.

These are among the most energy-- efficient furnaces you can buy today. They also are among the safest and most dependable. We are proud of the technological advances incorporated into the design of these furnaces. With only minimal care, your new furnace 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 furnace and the small amount of maintenance it takes to help keep it operating at peak efficiency year after year.

*The output capacity and any representations of efficiency for this furnace

are based on standard U.S. Department of Energy test procedures.

2. Burner sight glass for viewing burner flame.

3. Burner assembly (inside). Operates with energy--saving inshot burners and hot surface igniter for safe, dependable heating.

4. Redundant gas valve. Safe and efficient. Features 1 gas control with 2 internal shutoff valves and one throttling valve.

5. Vent outlet. Uses PVC pipe to carry flue gas from the furnace’s combustion system (right or left side).

6. Inducer motor. Pulls hot flue gases through the heat exchangers, maintaining negative pressure for added safety.

7. Blower access panel safety interlock switch.

8. Air filter and retainer (location in furnace may vary).

9. Condensate d rain connection. Collects moisture condensed from burned gases for disposal into home drain system. (Location in furnace varies.)

10. Heavy--duty blower. Circulates air across the heat exchangers to transfer heat into the home.

11. Everlastict Secondary condensing heat exchanger (inside).

Wrings out more heat through condensation. Constructed with polypropylene--laminated steel to ensure durability.

12. Primary serpentine heat exchanger (inside). Stretches fuel dollars with the S--shaped heat--flow design. Solid construction of corrosion--resistant aluminized steel means reliability.

13. Furnace control board.

14. 3--amp fuse provides electrical and component protection.

15. Light emitting diode (LED) on furnace control board. Status code light is for diagnosing furnace operation and service requirements.

16. Pressure switches ensure adequate flow of flue gas through furnace and out vent system.

17. Rollout switch (manual reset) to prevent overtemperature.

18. Junction box for 115--v electrical power supply. (May be located on right or left side)

19. Transformer (24v) behind furnace control board provides low--voltage power tofurnace controlboard and thermostat.

SAFETY CONSIDERATIONS

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. 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 may 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.

To minimize the possibility of serious personal injury, fire, furnace damage, or improper operation; carefully follow these safety rules:

S Your gas furnace uses air from outside the home for

combustion and vents flue gas to the outdoors. It is not to be installed using indoor air for combustion. The vent pipe must terminate outside the structure and must not be obstructed in any way. The air--intake pipe must terminate outside the structure or in a well ventilated area that is isolated from the living space and the garage (e.g. well ventilated attic or crawlspace). Do not block or obstruct air openings on furnace or spaces around furnace.

A92182

Fig. 4 -- Combustible Materials

S Do not cover the furnace, store trash or debris near it, or

in any way block the flow of fresh air to the unit.

S A furnace installed in an attic or other insulated space

must be kept free and clear of insulating material. Examine the furnace area when the furnace is installed or when insulation is added. Some materials may be combustible.

S 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.

S Keep the area around your furnace clear and free of

combustible materials, gasoline, and other flammable liquids and vapors.

A08617

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in personal injury/death or property damage.

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

FIRE AND UNIT OPERATION HAZARD

Failure to follow this warning could result in personal injury/death or property damage.

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 installed, and the space around the furnace.

WARNING

BEFORE STARTING YOUR FURNACE

Examine the furnace installation monthly to determine that:

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

2. The vent connector is in place, slopes upward and is physically sound without holes or excessive corrosion.

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

4. The physical support of the furnace is sound without sagging cracks, gaps, etc. around the base.

5. There are no obvious signs of deterioration of the furnace.

FIRE AND EXPLOSION HAZARD

Failure to follow this warning could result in personal injury/death or property damage.

Should the gas supply fail to shut off or if overheating occurs, turn off the manual gas valve to the furnace BEFORE turning off the electrical supply. (See Fig. 8.)

WARNING

S CHECK AIR FILTER: Before attempting to start

your furnace, be sure the furnace filter is clean and in place. See “Performing Routine Maintenance” section in this manual. Then proceed as follows:

Steps For Starting Your Furnace

1. Set your room thermostat to the lowest temperature setting. (See Fig. 7.)

2. Close the external manual gas valve. (See Fig. 8.)

STARTING AND SHUTTING DOWN YOUR FURNACE

Instead of a continuously burning pilot flame which wastes valuable energy, your furnace uses an automatic, hot surface ignition system to light the burners each time the thermostat starts your furnace. Follow these important safeguards:

S Never attempt to manually light the burners with a

match or other source of flame.

3. Turn OFF electrical supply to the furnace. (See Fig. 9.)

A92319

Fig. 6 -- Do Not Light Burner with Match

4. Remove main furnace door. (See Fig. 10.)

5. The gas valve will have a control switch to turn off and on.

S Read and follow the operating instructions on inside of

main furnace door, especially the item that reads as follows: Wait 5 minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information above on this furnace label. If you don’t smell gas, go to the next step.

S If a suspected malfunction occurs with your gas control

system, such as the burners do not light when they should, refer to the shutdown procedures on inside of main furnace door, or in the “Shutting Down Your Furnace” section and call your dealer as soon as possible.

6. After waiting 5 minutes, turn the control switch on the gas
