Replacing a Thermostat (See Figure 3)
1) Turn "OFF" the power to the water heater.
2) Remove the element and thermostat access door and the
insulation.
3) Disconnect the wires from the thermostat terminals.
4) Lift the thermostat bracket arms and slide the thermostat up to
remove it.
5) Replace the thermostat with a new thermostat of the same manu-
facturer and type.
6) Reconnect the wires on the thermostat terminals referring to the
corresponding wiring diagram in Figure 2.
7) Set the thermostat to the desired temperature (see Water
Temperature Regulation, page 9).
8) Replace the insulation and element and the thermostat access
door before turning "ON" the power to the water heater.
Temperature and Pressure-Relief Valve
Manually operate the temperature and pressure-relief valve at least
once a year, standing clear of the outlet to avoid being burned. Lift
and release the operating lever on the valve to make it operate free-
ly. If, after manually operating the valve, it fails to completely reset
itself and continues to discharge water, replace it with a new one.
Anode
This water heater is equipped with an anode that is designed to
prolong the life of the glass-lined tank. The anode is slowly
consumed, protecting the glass-lined tank from corrosion. The
anode should be inspected every two (2) years. If more than half of
the anode has been consumed, it should be replaced. Instructions
on how to change the anode can be obtained from the manufacturer.
The life expectancy of the water heater is reduced where a water
softener is introduced to fight hard water. The sodium salts added
by a softener make the water extremely conductive, therefore, the
anode are consumed more rapidly. Under these conditions, the
anode should be inspected yearly.
In certain water conditions, the anode will react with the water, pro-
ducing discoloured or smelly water. The most common complaint is
hot water that smells like rotten eggs. This phenomenon is the result
of the reaction between the magnesium of the anode and hydrogen
sulfide gas dissolved in the water, which occurs frequently in well
systems. This problem can usually be eliminated or reduced by
