- 12. After about 17 seconds, the gas valve permits gas to flow to the main burners where it is ignited. Hot flames begin to warm the furnace’s heat exchanger. After a time delay of approximately 25-45 seconds the furnace blower is switched on.
- 13. Set your thermostat to the temperature that satisfies your comfort requirements.
- SHUTTING DOWN YOUR FURNACE
- 1. Set your room thermostat to the lowest temperature setting (see Fig. 4).
- 2. Close the external manual gas valve (see Fig. 5).
- 3. Turn off electrical supply to the furnace (see Fig. 6).
- 4. Remove outer furnace door (see Fig. 7).
- 5. Turn the switch on the gas control to the OFF position (see Fig. 8).
- 6. Replace the outer furnace door (see Fig. 10).
- 7. If the furnace is being shut down because of a malfunction, call your dealer as soon as possible.

- 6. Inspect the filter. If torn, replace it.
- a. Factory specified disposable media filter — Do not clean. If dirty, replace only with media filter having the same part number and size. Install with airflow direction arrow pointing towards blower (some models may vary).
- b. Electronic Air Cleaner (EAC) — Refer to EAC Owner’s Manual for maintenance information (some models may vary).
- c. Factory specified disposable filter, do not clean. Replace it with a new filter of same size.
- d. Wash filter (if dirty) in sink, bathtub, or outside with a garden hose. Always use cold tap water. A mild liquid detergent may be used if necessary. Spray water through filter in the opposite direction of airflow. Allow filter to dry.
- 7. Reinstall clean air filter.
- 8. Replace filter cabinet door (see Fig. 18 and Fig. 19).
- 9. Turn on electrical supply to furnace (see Fig. 11).
- 6. Inspect the filter. If torn, replace it.

- COMBUSTION AREA AND VENT SYSTEM
- 1. Turn off electrical supply to the furnace and remove the access door (see Fig. 6 and Fig. 7).
- 2. Carefully inspect the gas burner for dirt, rust, or scale. Inspect the elbow, flue connection area, and the vent pipe for rust.
- Fig. 20 – Burner Flame
- 3. Inspect the vent pipe for a sag, holes, or a disconnection. A horizontal vent pipe must slope upward away from furnace. If rusty joints or seams, or signs of water leakages are found, call your dealer for service.
- 4. Restore electrical power to the furnace (see Fig. 11).
- 5. Start the furnace and observe its operation. If possible, watch the burner flames. Are they burning bright blue? If not or if you suspect some other malfunction, call your servicing dealer.
- 6. Replace the access door (see Fig. 10).

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 or replacing air filters. All other operations must be performed
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, 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 hazards which could result in personal
injury or death. CAUTION is used to identify unsafe practices which
would 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.
BEFORE STARTING YOUR FURNACE
Examine the furnace installation 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.
STARTING YOUR FURNACE
Your furnace uses an automatic, hot surface ignition system to light the
burners each time the thermostat signals the furnace to start.
Follow these important safeguards:
• Never attempt to manually light the burners with a match or other
source of flame.
A92319
Fig. 3 – Do Not Light Burner with Match
• 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.”
• 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.
• Should the gas supply fail to shut off or if overheating occurs, shut off
the gas valve to the furnace before shutting off the electrical supply.
• 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. Do not run the furnace without
a filter in place. Then proceed as follows:
STEPS FOR STARTING YOUR FURNACE
1. Set your room thermostat to the lowest temperature setting (see
Fig. 4).
A09564
Fig. 4 – Lowest Temperature Setting
2. Close the external manual gas valve (see
Fig. 5).
WARNING
!
FIRE OR EXPLOSION HAZARD
Failure to follow warnings could result in personal injury, death, or
property damage.
Keep insulation clear of furnace and maintain clearances shown on unit
clearance label.
WARNING
!
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, shut off
the gas valve to the furnace BEFORE shutting off the electrical supply
and install lockout tag.
