WATER LEAKAGE IS SUSPECTED

Refer to Leakage Checkpoint (next section).

1. Check to see if the heater drain valve is tightly closed.
2. If the outlet of the relief valve is leaking, it may be due to

one or more of the following:
Excessive water temperature

Faulty relief valve

Excessive water pressure

3. Excessive water pressure is the most common cause

of relief valve leakage. It is often caused by a “closed

system.” See

Closed Water Systems

and

Thermal

Expansion

in the “Installation” section of this manual.

4. Examine the area around the element for gasket

leakage.
Tighten the elements, or (if necessary) follow the

WATER AND LIME SCALE REMOVAL procedure to

replace the gaskets.

IF UNABLE TO IDENTIFY OR CORRECT THE SOURCE

OF MALFUNCTION

1. Turn the power supply to the water heater off.
2. Close the supply water inlet valve to the heater.
3. Contact a Qualified Service Agency in your area. Call

the toll free phone number on the back cover of this

Instruction Manual for assistance in locating a service

agency in your area.

REPLACEMENT PARTS

Call the phone number on the back cover of this Instruction

Manual for assistance in locating replacement parts. When

ordering parts, specify complete model no. (see rating

plate), quantity, and name of the part desired. Standard
