When such a condition is encountered, local codes or inspection agency should be consulted to determine which system is acceptable in your area. These may consist of:
•Installation of a second relief valve set to lower than the primary safety relief valve.
•An expansion tank of suitable pressure and provision to avoid water logging.
•Removal of the check valve.
4.Examine the flange area of the elements for gasket leakage.
•Tighten the bolts or, if necessary, follow the WATER AND LIME SCALE REMOVAL procedure to replace the gaskets.
•Refer to “LEAKAGE CHECKPOINTS” on page 22.
Anode rod deterioration depends on water conductivity, not necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/or replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by a qualified technician, and at a minimum should be checked annually after the warranty period.
IF YOU CANNOT IDENTIFY OR CORRECT THE SOURCE OF MALFUNCTION
1.Place the water heater electrical switch in the OFF position
2.Close the supply water inlet valve to the heater.
3.Contact your dealer.
ANODE MAINTENANCE | REPLACEMENT PARTS |
The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This does not affect the water’s taste or color. The rod must be maintained to keep the tank in operating condition.
Replacement parts may be ordered through dealers, authorized servicers or distributors. Refer to Yellow Pages for where to call or contact the State Water Heaters, 500 Lindahl Parkway, Ashland City, TN 37015. When ordering parts, specify complete model no., serial no., (see rating plate), quantity and name of part desired. Standard hardware items should be purchased locally.
