Anleitung Zusammenfassung
When dirt, soot, scale, or rust is allowed to build up, your furnace can suffer a loss of efficiency and perform improperly. Accumulations on the main burners can result in firing out of normal sequence. This delayed ignition creates an alarmingly loud sound. CAUTION! If your furnace makes an especially loud noise when the main burners light, shut down your furnace and call your dealer. Failure to follow this caution would result in minor property damage. To inspect the combustion area and vent system, you will need a flashlight. Refer to Fig. 3 or 4, and proceed as follows: 1. Turn off gas and electrical supplies to the furnace and remove the main furnace door. (See Fig. 9, 10, and 11.) 2. Remove burner enclosure front. (See Fig. 37 or 38.) Inspect the gas burners, igniter area, and remainder of furnace for dirt, rust, soot, or scale. CAUTION! If dirt, rust, soot, or scale accumulations are found, call your dealer. Do not operate your furnace. Failure to follow this caution would result in minor property or product damage. 3. Inspect the combustion-air and vent PVC pipes for sags, holes, cracks, or disconnections. Horizontal portions of pipes must slope downward toward furnace. UPFLOW 37 9 DOWNFLOW 4. Reinstall burner enclosure front. 5. If your furnace is free of the above conditions, replace main furnace door and turn on electrical and gas supplies to your furnace. (See Fig. 16, 17, and 18.) 6. Start the furnace and observe its operation. Watch the burner flames to see if they are clear blue, almost transparent. (See Fig. 39.) If you observe a suspected malfunction, or the burner flames are not clear blue, call your dealer. HEADING SOUTH FOR THE WINTER? DON’T FORGET YOUR FURNACE! CAUTION! If the furnace is installed in an unconditioned space where the ambient temperatures may be 32°F or lower, freeze protection measures must be taken to prevent minor property or product damage. Since the furnace uses a condensing heat exchanger, some water will accumulate in the unit as a result of the heat transfer process. Therefore, once it has been operated, it cannot be turned off and left off for an extended period of time when temperatures will reach 32°F or lower unless winterized. Follow these procedures to winterize your furnace: 1. Obtain propylene glycol (RV/ swimming pool antifreeze or equivalent). CAUTION! Do not use ethylene glycol (Prestone II antifreeze coolant or equivalent). Failure of plastic components will occur. 2. Turn off electrical supply to the furnace. (See Fig. 20.) 3. Remove main furnace door. (See Fig. 23.) 4. Remove upper inducer housing drain connection cap. (See Fig. 40.) 5. Connect field-supplied 1/2-in. ID tube to upper inducer housing drain connection. 6. Insert field-supplied funnel into tube. 40 41 7. Pour 1 quart of antifreeze into funnel/tube. Antifreeze should run through inducer housing, overfill condensate trap, and flow into open field drain. (See Fig. 41.) 8. Remove funnel and tube from inducer housing and replace drain connection cap and clamp. 9. Replace main furnace door. (See Fig. 34.) 10. Propylene glycol need not be removed before restarting furnace. A CHECK-UP CHECKLIST Your furnace represents an important investment in your family’s comfort and your home’s value. To keep it performing properly and to prevent future problems, have a trained service specialist give your furnace a professional check-up annually. The following checklist can be used as a guideline to proper service: • Inspect all flue gas passages, burners, heat exchangers, coupling box(es), and inducer assembly. • Inspect all combustion-air and vent piping inside structure and pipe terminations outside the structure. • Check gas pipes leading to and inside of your furnace for leaks. • Inspect and clean the blower motor and wheel. NOTE: The inducer and blower motors are pre-lubricated and require no additional lubrication. These motors can be identified by the absence of oil ports on each end of the motor. • Inspect and change or clean air filter( s) if necessary. • Inspect all supply- and return-air ducts for obstructions, air leaks, and insulation. Remedy any problem when necessary. • Inspect the return-air duct connection( s) at the furnace to ensure it is physically sound, sealed to the furnace casing, and terminates outside the space containing the furnace. • Inspect electrical wiring, connections, and components for loose connections. • Perform an operational checkout to determine whether your furnace is working properly and if it requires adjustments. • Inspect all condensate drain tubes and condensate trap assembly for leaks. The condensate removal system should be cleaned annually by a qualified service agency. Refer to the Service and Maintenance Instructions for further information. • Examine the physical support of the furnace. The support should be sound with no cracks, sagging, gaps, etc. around the base. • Check furnace for any obvious signs of deterioration. BEFORE YOU REQUEST A SERVICE CAL...
