- TABLE OF CONTENTS
- 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. 5 – Close Valve
- Fig. 6 – Turn Off Electrical Supply
- Fig. 7 – Remove Furnace Door

- 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. 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.

- 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).
