Resumen del manual
Follow the procedures in the “Shutting Down Your Furnace” section of this manual. —5— SUGGESTION: Setting the thermostat back a few degrees— and compensating for the difference with warmer clothing— can make a big difference in your fuel consumption on extremely cold days. The few degrees at the top of your thermostat “comfort level” are the most costly degrees to obtain. When the room temperature drops below the temperature selected on the thermostat, the furnace will be switched on automatically. When the room temperature reaches the degree selected on the thermostat, the furnace will be automatically switched off. Some thermostats have a “fan” switch with 2 selections: AUTO or ON. When set on AUTO, the furnace blower cycles on and off, controlled by the thermostat. In the ON position, the furnace blower runs continuously except for a 45-sec delay at the “call for heat.” This keeps the temperature level in your home more evenly balanced. It also continuously filters the indoor air. SHUTTING DOWN YOUR FURNACE Once the heating season has ended, or if you ever suspect a malfunction, you’ll want to turn your furnace off. The following procedures and the procedures on the lighting/operating instructions label on your furnace must be followed: 1. Set your room thermostat to the lowest temperature setting. (See Fig. 17.) 2. Tlim OFF the electrical supply to your furnace. (See Fig. 18.) 3. Remove the access door(s) from your furnace. Lift up and out at the bottom. (See Fig. 9 for upflow and Fig. 10 for downflow furnaces.) NOTE: The blower access door must be installed to permit furnace operation. 4. lb shut off the burners but keep the pilot light burning, turn the control knob of the internal gas valve to the PILOT position. 5. To shut off the complete gas control system (pilot and burners), turn (and depress if required) the control knob on the internal gas valve clockwise to the indicated OFF position. 6. Close the external manual gas valve. (See Fig. 7.) 7. Replace the access door. (See Fig. 15 or 16.) On downflow furnaces, remove the blower access door, install the control access door, then reinstall the blower access door and secure with 2 screws. 8. If the furnace is being shut down because a malfunction is suspected, call your service dealer as soon as possible. NOTE: To conserve energy when the heating season has ended, you should shut down your manually ignited pilot. If the furnace blower is to be used during the cooling season, turn the control knob on the internal gas valve to OFF. Leave the electrical supply to the furnace turned ON. PERFORMING ROUTINE MAINTENANCE With the proper maintenance and care, your furnace will operate economically and dependably. Basic maintenance, which can easily be accomplished by following the directions, is found on this and the following pages. However, before beginning maintenance, follow these safety precautions: W5T^ Jl Afirroi UVACI F.1 I 'VATL Î >KK '1 rurr lllll.'l I 1 IN- P 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. ;>/i:.'CAtUTi ■^WTJTlOl1 The air filter for upflow furnaces is normally located in the blower compartment. Filters for the downflow furnaces are normally located in the return-air plenum above the blower. 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: • UPFLOW FURNACES ONLY: 1. Him OFF the electrical supply to the furnace. (See Fig. 18.) 2. Remove control and blower access doors. 3. Push filter retainer toward the bracket opening to release the filter. (See Fig. 19.) 4. Gently remove the filter and carefully turn the dirty side up (if dirty) to avoid “spilling” dirt from the filter. (See Fig. 20.) 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 de- —6— tergent 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. 15,16, and 21.) 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. UPFLOW FURNACE FILTER TABLE • DOWNFLOW ...
