- SAFETY CONSIDERATIONS
- BEFORE STARTING YOUR FURNACE
- 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
- STEPS FOR STARTING YOUR FURNACE
- 1. Set your room thermostat to the lowest temperature setting (see Fig. 4).

- Fig. 9 – Control Switch to ON
- Fig. 10 – Furnace Door Replaced
- Fig. 11 – Turn On Electrical Supply
- Fig. 12 – Open Valve
- 11. Set the room thermostat to a temperature slightly above the room temperature. This will automatically signal the furnace to start. The inducer motor will start and the hot surface igniter will energize. When hot, the igniter will have an orange glow
- 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.
- PERFORMING ROUTINE MAINTENANCE
- FILTERING OUT TROUBLE
- 1. Turn off the electrical supply to the furnace (see Fig. 13).

- Fig. 14 – Removing Side Filter Cabinet Door
- Fig. 15 – Removing Bottom Filter Cabinet Door
- Fig. 16 – Slide Side Filter Out of Furnace
- Fig. 17 – Slide Bottom Filter Out of Furnace
- 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.

- Fig. 19 – Replace Bottom Filter Cabinet Door
- 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).

COMBUSTION AREA AND VENT SYSTEM
Inspect the combustion area and vent system before each heating season.
An accumulation of dirt, soot, or rust can mean a loss of efficiency and
improper performance. Buildups on the main burners can cause faulty
firing. This “delayed ignition” is characterized by an alarmingly loud
sound.
NOTE: If your furnace makes a loud noise when the main burners are
ignited, shut down the furnace and call your servicing dealer. Use your
flashlight and follow these steps for inspecting the combustion area and
vent system of your furnace:
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.

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).
BEFORE YOU REQUEST A “SERVICE CALL”
Before you call for service, check for several easily solved problems:
• Check for sufficient airflow. Check the air filter for dirt. Check for
blocked return-air or supply-air grilles. Be sure they are open and
unobstructed. If this isn’t the cause of the problem, call your servicing
dealer. If your furnace isn’t operating at all, check the following list
for easily solved problems:
• Is your thermostat set above room temperature? Is the HEAT mode
selected?
• Is the electrical power supply switch on? Is the blower access door
firmly in place? Are any fuses blown? (There is a fuse on the furnace
control.) Has a circuit breaker tripped?
• Is the manual shut-off valve in the gas supply pipe leading to the
furnace open? Does the lever point in the same direction that the pipe
runs (open)? Or is it at a right angle to the pipe (closed)?
NOTE: Before proceeding with the next checks, turn off the electrical
power supply to the furnace. Remove access door.
• Is the switch on the gas valve turned to the ON position? If this or the
preceding check shows an interruption in the gas supply, make sure
the gas has not been shut off for safety reasons. If nothing else seems
to be wrong, follow the start-up procedures found on pages 3 and 4 of
this booklet.
• Check the manual reset limit switches located on the ends of the
burner enclosure (see
Fig. 1 and Fig. 2). If the furnace has
experienced a high-temperature condition due to inadequate
combustion air, these switches will shut off the furnace. Reset the
switches by pushing the button on the switch. If the switch trips a
second time, turn off the furnace and call for service.
• If your furnace still fails to operate, call your servicing dealer for
troubleshooting and repairs. Tell your dealer the model and serial
numbers for your furnace. (You should have them recorded on page 7
of this booklet.) By knowing exactly which furnace you have, the
dealer may be able to offer suggestions over the phone or save
valuable time through knowledgeable preparation for the service call.
In addition to the type of routine maintenance you might be willing to
perform, your furnace should be inspected regularly by a properly
trained service technician. You should work with your dealer or service
technician to assure your inspection includes the following at a
minimum.

!
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or death.
For proper and safe operation the furnace needs air for combustion and
ventilation. Do not block or obstruct air openings on the furnace, air
opening to the area in which the furnace is installed, and the space
around the furnace.

Failure to follow this caution may result in personal injury.
If for some reason the vent is blocked, the draft safeguard switch will
shut off the furnace. (See Page 2 for switch location.) The switch will
automatically reset after the furnace cools off. If the furnace fails to
operate, contact a qualified service agency.
