- 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.

- 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.

- 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).

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.
NOTE: If the main burners fail to ignite, the furnace control system will
go through three more ignition cycles. Then if burners fail to ignite, the
system will lockout. If lockout occurs or the blower does not come on,
shut down your furnace and call your dealer for service.
13. Set your thermostat to the temperature that satisfies your comfort
requirements.
SUGGESTION: Setting the thermostat back a few degrees—and
compensating for the difference with warmer clothing—can make a big
difference in your fuel consumption on extremely cold days. The few
degrees at the top of your thermostat “comfort level” are the most costly
degrees to obtain.
When the room temperature drops below the temperature selected on the
thermostat, the furnace will switch on automatically. When the room
temperature reaches the setting selected on the thermostat, the furnace
will be automatically switched off.
Continuous Fan Operation - Some thermostats have a “FAN” switch
with 2 selections: AUTO and ON. When thermostat is set on AUTO, the
furnace blower cycles on and off, controlled by the thermostat. In ON
position, the furnace blower runs continuously except for a 42-62 sec
delay at the “call for heat.” Continuous fan keeps the temperature level
in your home more evenly balanced. It also continuously filters the
indoor air.
SHUTTING DOWN YOUR FURNACE
Should you ever suspect a malfunction in your furnace, you will need to
turn the furnace off. The following procedures must be followed:
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
With proper maintenance and care, your furnace will operate
economically and dependably. Instructions for basic maintenance are
found on this and the following pages. However, before beginning
maintenance, follow these safety precautions:
FILTERING OUT TROUBLE
A dirty filter will cause excessive stress on the furnace, heat exchanger,
and blower motor and can cause it to overheat and automatically shut
down. The furnace filter should be checked every 4 weeks and cleaned
or replaced if necessary.
If installed with factory specified disposable media filter, check or
replace filter before each heating and cooling season. Replace disposable
media filter at least twice a year.
If your furnace filter needs replacing, be sure to use the same size and
type of filter that was originally specified.
The air filter for the furnace may be located in a filter cabinet/rack
attached to the side or bottom of the furnace. If air filter has been
installed in another location, contact your dealer for instructions. To
inspect, clean and/or replace the air filter(s), follow these steps:
1. Turn off the electrical supply to the furnace (see
Fig. 13).

Fig. 13 – Turn Off Electrical Supply
2. Remove filter cabinet door/rack.
3. Remove filter cabinet door (see
Fig. 14 and Fig. 15).
4. It may be necessary to remove 1 thumbscrew.

WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Turn off electrical power supply to your furnace before removing the
access doors to service or perform maintenance.
CAUTION
!
CUT HAZARD
Failure to follow this caution may result in personal injury.
Although special care has been taken to minimize sharp edges, be
extremely careful when handling parts or reaching into the furnace.
Wear safety glasses, gloves, and appropriate protective clothing.
CAUTION
!
UNIT PERFORMANCE HAZARD
Failure to follow this caution may result in product damage.
Never operate your furnace without a filter in place. Doing so may
damage the furnace blower motor. An accumulation of dust and lint on
internal parts of your furnace can cause a loss of efficiency.
