manual abstract


See Fig. 20. Remove both access doors from your upflow furnace—the control access door first, and the blower access door second. Lift doors up and out. See Fig. 10 or 11. Remove only the blower access door of your downflow furnace. 2. Remove the filter. • UPFLOW FURNACES ONLY: Push the filter retainer toward the back of the furnace until it clears the flange at the front of the furnace casing. Gently remove the filter and carefully turn it over to avoid spilling any dirt that may be on the filter. See Figs. 21 and 22. • DOWNFLOW FURNACES ONLY: Remove the two filters from inside the retum-air plenum which is attached to the top of your furnace. Reaching in and up through the blower access area, tip the left-side filter toward center and raise it from the v-shaped channel in which it rests. Lower and remove the filter gently so that you do not dislodge any dirt that may have accumulated on it. Now, remove the filter on the right side in similar manner, down through the left-hand side of the blower compartment. See Figs. 23 and 24. 7 3. Inspect the filter. 4. If you have a dirty disposable filter, replace it with a new one. See Furnace Filter Table for replacement filter size. If you have a dirty reusable filter, wash it in a sink or tub; or use an outside garden hose to clean it. Always use cold water. . . and a mild liquid detergent, if necessary. Flush the filter from the side opposite of accumulated dirt. Then, allow the filter to air dry. After the reusable filter is dry, reinstall it with its cross-mesh binding side facing the furnace blower. UPFLOW FURNACE ONLY: Replace the filter retainer under the flange of the furnace casing. 5. Replace the access door(s) and restore electrical power to the furnace. A CAUTION Never operate your furnace without a filter. An accumulation of dust or lint on internal parts can cause a loss of efficiency, and damage to the blower motor and air conditioning system (when used.) NOTE: Refer to the unit Installation Instructions for blower motor oiling information if oil ports are provided.

An accumulation of dirt, soot, or rust can mean a loss of efficiency and unsafe performance. Buildups on the burners can cause faulty firing. This “delayed ignition” is characterized by an alarmingly loud sound. If your furnace makes a loud noise when the burners are ignited by the pilot, shut down the furnace—and call your servicing dealer. Refer to the lighting/operating instruction label affixed to your furnace blower access door (See Figs. 1 and 2 for door identification) for shutdown procedures. 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(s). See Figs. 9 and 10 or 11. The blower access door must be installed to permit furnace operation. On downflow furnaces, the blower access door must be removed before the control access door is removed, then reinstalled. 2. Carefully inspect the burner and the pilot areas for dirt, rust, or scale. See Fig. 25. Then, inspect the vent connection area, and the vent pipe for rust. NOTE: If dirt, rust, soot, or scale accumulations or other discrepancies are found, call your servicing agency. 3. Inspect the vent pipe for a sag, holes, obstruction, or a disconnection. Horizontal vent pipes must slope upward at least 1/4 inch per linear foot away from the furnace. A 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 service technician immediately. Refer to the lighting/operating instruction label affixed to your furnace blower access door for shutdown procedures. 4. Replace the access door and restore electrical power to the furnace. See Fig. 15 or 16. On downflow furnaces, remove the blower access door, install the control access door, then reinstall the blower access door. 5. Start the furnace and observe its operation. If possible, watch the burner flames. See Fig. 25. Are they burning bright blue? If not (or if you suspect some other malfunction), call your servicing dealer. Refer to the lighting/operating instruction label affixed to your furnace blower access door for shutdown procedures.
