A FAILURE TO FOLLOW THIS WARNING COULD RESULT IN PERSONAL INJURY OR DEATH. ! CAUTION ALTHOUGH SPECIAL CARE HAS BEEN TAKEN TO MINIMIZE SHARP EDGES, BE EXTREMELY CAREFUL WHEN HANDLING PARTS OR REACHING INTO THE FURNACE. ! FILTERING OUT TROUBLE A dirty filter will cause excessive stress on the furnace blower motor and can cause it to overheat and automatically shut down. The furnace filter should be checked every 3 or 4 weeks and cleaned if necessary. If your furnace filter needs replacing, be sure to use the same size and type of filter that was originally supplied. Use the furnace filter table (see page 7) and compare your furnace size with the proper filter size. CAUTION! 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. The air filter for upflow furnaces is normally located in the blower compartment. If the filters have been installed in another location, contact your dealer for instructions. To inspect, clean and/or replace the air filter(s), follow these steps: c UPFLOW FURNACES ONLY: 1. Turn OFF the electrical supply to the furnace. (See Fig. 14.) 2. Remove control and blower access doors. 3. Push filter retainer toward the bracket opening to release the filter. (See Fig. 15.) 4. Gently remove the filter and carefully turn the dirty side up (if dirty) to avoid “spilling’’ dirt from the filter. (See Fig. 16.) 15 16 —6— 5. Inspect the filter. If torn, replace the filter. 6. Wash the filter (if dirty) in a 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 the filter in the opposite direction of airflow (through the cross- mesh binding side). Allow filter to dry. 7. Reinstall the clean filter with its cross-mesh binding side facing the furnace blower. 8. Put filter retainer back in the bracket opening and lock it in place. 9. Replace the blower and control access doors and turn ON electrical power to your furnace. (See Fig. 12 and 17.) NOTE: If side return ducts are used, two filters may be required in some models. The procedure listed above may be used to remove side filters. NOTE: If dirt, rust, soot, or scale accumulations are found, call your servicing dealer. DO NOT OPERATE THE FURNACE. 3. Inspect the vent pipe for a sag, holes, or a disconnection. A horizontal vent pipe must slope upward. If rusty joints or seams, or signs of water leakages are found call your dealer for service. 17 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 or pilot assembly can cause faulty firing. This “delayed ignition” is characterized by an alarmingly loud sound. If your furnace makes a loud noise when the main burners are ignited by the pilot, shut down the furnace—call your servicing dealer. Refer to the lighting instructions label on the blower door for shutdown procedures.

Filter may be field modified by cutting as required. Alternate sizes and additional filters may be ordered from your dealer. Use your flashlight and follow these steps for inspecting the combustion area and vent system of your furnace: 1. Turn off the electrical supply to the furnace and remove the access doors. (See Fig. 6 and 7.) 2. Carefully inspect the gas burner (See Fig. 18) for dirt, rust, or scale. Then, inspect the relief box, flue connection area, and the vent pipe for rust. WARNING ! If holes are found—or if the vent pipe is obstructed or is not connected—toxic fumes can escape into your home. DO NOT OPERATE YOUR FURNACE. Call your dealer for service. A failure to follow this warning could result in personal injury or death. 4. Replace the access doors and restore electrical power to the furnace. Be sure bottom door flange is inside of the furnace casing. (See Fig. 12 and 17.) 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. BEFORE YOU REQUEST A SERVICE CALL BEFORE YOU CALL FOR SERVICE, CHECK FOR SEVERAL EASILY SOLVED PROBLEMS: M 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, call your servicing dealer. If your furnace isn’t operating at all, check the following list for easily solved problems: M Is your thermostat set above roo...
