softened water is exceedingly corrosive because the process substitutes sodium ions for magnesium and calcium ions. The use of a water softener may decrease the life of the water heater tank. The anode rod should be inspected after 3 years of use and annually thereafter until the condition of the anode rod dictates its replacement.

NOTE: Artiﬁcially softened water requires the anode rod to be inspected annually.

The following are typical (but not all) signs of a depleted anode rod:

•The majority of the rods diameter is less than 3/8”.

•Signiﬁcant sections of the support wire (approx. 1/3 or more of the anode rod’s length) are visible.

If the anode rod show signs of either or both it should be replaced.

NOTE: Whether re-installing or replacing the anode rod, check for any leaks and immediately correct if found.

1.Disconnect the electrical power to the water heater.

2.Close the shutoff valve on the cold-water line.

3.Follow the instructions in the “Draining The Tank” section in the Operating Manual to drain approximately 5 gallons (20 litres) of water from the tank.

4.Close the drain valve.

5.Disconnect the hot-water piping from the Hot Water Outlet Nipple/Anode.

6.Remove the Hot Water Outlet Nipple/Anode.

TEMPERATURE-PRESSURE RELIEF VALVE OPERATION

FIGURE 37

The temperature-pressure relief valve lever must be operated at least once a year to ensure that the water ways are clear. When checking the temperature-pressure relief valve operation, make sure that:

1.	No one is in front of or around the outlet of the
	temperature-pressure relief valve discharge line.
2.	The water discharge will not cause any property
	damage, as the water may be extremely hot.

•If it is nessesary to replace the anode rod, refer to the detailed instructions that are supplied with the replacement anode.

•See the “Parts Reference Illustration” for anode rod location.

Else:

•Re-install the Hot Water Outlet Nipple/Anode.

•Reconnect the hot-water piping to the Hot Water Outlet Nipple/ Anode.

•Open the shutoff valve on the cold-water line.

•Fill the tank following the instructions in the “Filling The Water Heater”.

•Check for leaks and repair as required.

•Reconnect the electrical power to the water heater.

•Restart the water heater following the “Lighting Instructions”.

3. A discharge line is connected to this valve, directing

the flow of hot water from the valve to a proper

placement for disposal.

If water does not ﬂow freely when the lever is in the open position, replacement of the valve is required. Turn off the cold water inlet heater and call a qualiﬁed service man.

If after manually operating the valve (see Figure 37), it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one.

If the temperature-pressure relief valve on the appliance weeps or discharges periodically, this may be due to thermal expansion. You may have a check valve installed in the water line or a water meter with a check valve. Consult your local water supplier or a qualiﬁed service agency for further information. Do not plug the temperature-pressure relief valve.

Motors are permanently lubricated and do not need periodic lubrication. Keep fan and motor free of dust and dirt by cleaning annually.
