- 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. 4 – Lowest Temperature Setting
- Fig. 5 – Close Valve
- Fig. 6 – Turn Off Electrical Supply
- Fig. 7 – Remove Furnace Door
- Fig. 8 – Control Switch to OFF
- 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. 13 – Turn Off Electrical Supply
- 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. 18 – Replace Side Filter Cabinet Door
- 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).

WELCOME TO TODAY’S GENERATION OF
COMFORT
Congratulations! Your new gas furnace is a sound investment which will
reward you and your family with years of warm memories winter after
winter.
Not only is your new furnace energy efficient, it is also extremely
reliable. Spend just a few minutes with this booklet to learn about the
operation of your new furnace-and the small amount of maintenance it
takes to keep it operating at peak efficiency. Years went into the
development of your new furnace. Take a little time now to assure its
most efficient operation for years to come.
IMPORTANT FACTS (DO’S AND DON’TS)
• DO: READ AND UNDERSTAND THIS MANUAL.
• DO: Have your furnace and vent system inspected annually by a
qualified service technician.
• DO: Inspect your filter monthly and clean or replace when needed.
• DO: Provide adequate airflow to the furnace for efficient combustion
and safe ventilation.
• DO: Keep your furnace free and clear of insulating material (some
materials may be combustible. Examine the furnace area when the
furnace is installed or when insulation is added.
• DO NOT: Enclose your furnace in an airtight room or seal it behind
solid doors.
• DO NOT: Keep combustible materials, gasoline, and other flammable
liquids or vapors around your furnace.
• DO NOT: Cover your furnace in any manner.
• DO NOT: Store anything (including trash or debris) near your furnace.
• DO NOT: In any way block or restrict airflow around your furnace.
• DO NOT: In any way block or restrict airflow to your supply air and
return air grills.
• DO NOT: Use your furnace room as a broom closet or a place to store
any kind of chemical or cleaner.
• DO NOT: Contaminate the air used for combustion of your furnace
with any kind of chemical or fumes. This could also cause heat
exchangers, metal vent systems or components to deteriorate.
NOTE: These chemicals or fumes are present in many products around
the home, such as: water softener salts, any type of household cleaning
product, any type of laundry product, adhesives, paints, varnishes, paint
strippers, waxes and plastics, etc.
During remodeling be sure the combustion air is fresh and
uncontaminated. If these compounds are burned in your furnace, the heat
exchangers and metal vent system may deteriorate.
NOTE: The qualified installer or agency must use only
factory-authorized replacement parts, kits, and accessories when
modifying this product.
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.)
