Anleitung Zusammenfassung
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. 3. Disconnect wires or connectors to flame rollout switch, gas valve, igniter, and flame sensor. 4. Using backup wrench, disconnect gas supply pipe from gas valve. 5. Remove screws attaching burner box to cell panel. (See Fig. 4.) NOTE: Burner box, manifold, gas valve, and burner assembly should be removed as 1 assembly. 6. Clean heat exchanger openings with a vacuum and a soft brush. (See Fig. 5.) NOTE: After cleaning, inspect heat exchangers to ensure they are free of all foreign objects that may restrict flow of combustion products. 7. Reverse items 4 and 5 for reassembly. CAUTION! UNIT MAY NOT OPERATE Failure to follow this caution may result in improper unit operation. The ground wire from the gas valve MUST be attached to the burner box attachment screw or furnace lockout may occur. 8. Refer to furnace wiring diagram and connect wires to flame rollout switch, gas valve, igniter, and flame sensor. 9. Reconnect pressure switch tubes to gas valve and intake housing. Refer to tube routing label on main furnace door for proper tube location. Be sure tubes are not kinked. (See Fig. 6 - --14.) 10. Turn on gas and electrical supplies to furnace. 11. Check furnace operation through 2 complete heat operating cycles. Burner flames should be clear blue, almost transparent. (See Fig. 15.) !WARNING FIRE OR EXPLOSION HAZARD Failure to follow the safety warnings could result in personal injury, death, or property damage. Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connections. 12. Check for gas leaks. 13. Replace main furnace door. B. Secondary Heat Exchangers NOTE: The condensing side (inside) of secondary heat exchangers CANNOT be serviced or inspected. A small number of bottom outlet openings can be inspected by removing inducer assembly. See Flushing Collector Box and Drainage System section for details on removing inducer assembly. Procedure 5—FlushingCollector Boxand Drainage System 1. Turn off gas and electrical supplies to furnace. 2. Remove main furnace door. 3. Disconnect inducer motor and pressure switch wires or connectors. BurnerFace A07734 Fig. 15 - --Burner Flame 58HDX 15 16 GASKET A07828 Fig. 16 -- Gasket on Collector Box 4. Disconnect pressure switch tubes. 5. Disconnect vent pipe from inducer housing outlet by loosening clamp. 6. Disconnect drain tube from inducer housing. (See Fig. 6 -- 14.) 7. Remove inducer housing assembly by removing 4 bolts attaching assembly to cell panel. 8. Flush inside of collector box with water until discharge from condensate trap is clean and runs freely. NOTE: Ensure that drain tube disconnected from inducer housing is higher than collector box opening or water will flow out tube. 9. Inspect inside area of collector box for any pieces of foreign materials and remove if present. UNIT DAMAGE HAZARD Failure to follow this caution may result in furnace component damage. DO NOT use wire brush or other sharp object to inspect or dislodge materials in secondary heat exchangers as failure of the secondary heat exchanger may occur. Flush with water only. ! CAUTION 10. Reassemble inducer assembly by reversing items 5 through 7. Tighten the vent coupling screw(s) to 15 in.--lb. of torque. NOTE: If gasket between inducer housing and collector box is damaged in any way, it must be replaced. (See Fig. 16.) 11. Refer to furnace wiring diagram and connect wires to inducer motor and pressure switch or connectors. 12. Reconnect pressure tubes to pressure switch. See diagram on main furnace door for proper location of tubes. Be sure tubes are not kinked. (See Fig. 6 -- 14.) 13. Turn on gas and electrical supplies to furnace. 14. Check furnace operation through 2 complete heat operating cycles. Check area below inducer housing, vent pipe, and condensate trap to ensure no condensate leaks occur. If leaks are found, correct problem. FIRE OR EXPLOSION HAZARD Failure to follow the warnings could result in personal injury, death, or property damage. Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connections. ! WARNING 15. Check for gas leaks. 16. Replace main furnace door. Procedure 6 — Servicing Hot Surface Igniter The igniter does NOT require annual inspection. Check igniter resistance before removal. 1. Turn off gas and electrical supplies to furnace. 2. Remove main furnace door. 3. Disconnect igniter wire connection. 58HDX 17 1. Connect Y-terminal in furnace as shown for proper blower operation. 2. Some thermostats require a “C” terminal connection as shown. 3. If any of the original wire, as supplied, must be replaced, use same type or equivalent wire.
