41 SECTION X: MAINTENANCE DANGER DO NOT ATTEMPT TO REPAIR GAS VALVE. DO NOT ATTEM PT TO REPAIR I GNITION MO DULE. DO NOT ATTEM PT TO REPAIR VE NTURI. DO NOT ATTEMPT TO REPAIR THERMOSTAT BOARD. DO NOT ATTEMPT TO REPAIR TRANSFORMER. DO NOT ATTEMPT TO REPAIR PRESSURE SWITCH.
42 DRAINING WATER HE ATER The water heater m ust be drained if it is to be shut down and exposed to freezing tem peratures. Maintenance and service proced ures may also require draining the water heater. 1. Turn off the water heate r electrical disconnect switch.
43 ANODE INSPECTION AND REPLACEMENT This water heater is equipped with multiple sacrificial anod es. Anodes protect the gl ass-lin ed tank from corrosion by sacrific ing themselves through el ectrolysis. When the anode m aterial is consumed, th er e is no more protection and corrosion of the tank accelerates.
44 Figure 28. Powered Anode locations DRAIN VALVE AN D TANK ACCESS PANEL The water heaters a re equippe d with a ¾ inch ( 1.9 cm) inch drain valve . An access panel covers t he cleanout openi ng in the tank, which is sealed by a gasket and cover.
