The furnace filter should be checked every 3 or 4 weeks and cleaned 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 once a year. If your furnace filter needs replacing, be sure to use the same size and type of filter that was originally supplied. 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 is located in the factory- supplied filter cabinet attached to the side or bottom of the blower cabinet. 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 electrical supply to furnace (See Fig. 7.) 5 2. Remove filter cabinet door (See Fig. 18 and 19.) NOTE: It will be necessary to remove 1 thumbscrew 3. Slide air filter out of filter cabinet. Keep dirty side up (if dirty) to avoid spilling dirt. See Fig. 20 and 21.) 4. Inspect the filter. If torn, replace it. NOTE: If washable filter that was shipped with the furnace has been replaced by: a) Factory specified disposable media filter – Do not clean.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. b) Electronic air cleaner (EAC) – Refer to EAC owner’s Manual for maintenance information. 5. 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. 6. Reinstall clean air filter. 7. Replace filter cabinet door. (See Fig. 22 and 23.) 8. Turn on electrical supply to furnace (see Fig. 12.) AIR FILTER LOCATED IN FILTER CABINET: FILTER CABINET HEIGHT (IN.) FILTER SIZE (IN.) FILTER TYPE 16 (1)16x25x1* or (1)16x25x4-5/16 Cleanable Disposable * Factory provided with the furnace. Filters may be field modified by cutting filter material and support rods (3) in filters. Alternate sizes and additional filters may be ordered from your dealer. CAUTION! Use care when cutting support rods in filters to protect against flying pieces and sharp rod ends. Wear safety glasses, gloves, and appropriate protective clothing. Failure to follow this caution could result in personal injury. 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. If your furnace makes a loud noise when the main burners are ignited, shut down the fur- nace—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 the electrical supply to the furnace and remove the access door. (See Fig. 7 and 8.) 2. Carefully inspect the gas burner (see Fig. 17) for dirt, rust, or scale. Then inspect the elbow, flue connection area, and the vent pipe for rust. 17 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 away from furnace. If rusty joints or seams, or signs of water leakages are found call your dealer for service. 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 door and restore electrical power to the furnace. (See Fig. 12.) 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 21 22 23 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, 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 board.) Has a circuit breaker tripped? • Is the manual shutoff valve in the gas supply pipe leading to the furnace open? Does the lever point in th...
