heater is in the ON position. The pilot toggle switch on the
cabinet should be ON.
In some areas water heater electrical service may be limited
by the power company. If the heater operates on a controlled
circuit, heater recovery may be affected.
The optional manual override switches on the cabinet front may
be turned off, de-energizing the elements.
2. Check the fuses.
The electrical disconnect switch usually contains fuses.
The water heater has fuses located behind the cabinet front

Large demands require a recovery period to restore water temperature.
5. Cold incoming water temperature will lengthen the time required
to heat water to the desired temperature.
If the heater was installed when incoming water temperature
was warm, colder water creates the effect of less hot water.

LEAKAGE CHECKPOINTS
1. Check to see if the drain valve is tightly closed.
2. The apparent leakage may be condensation which forms on
cool surfaces of the heater and piping.

Excessive water pressure is the most common cause of relief valve
leakage. Water supply systems may, because of code requirements
or such conditions as high line pressure, among others, have installed
devices such as pressure reducing valves, check valves, and back
