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 MAINTENANCE
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.
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.
