NOTE: These instructions are written for element clean-

is necessary to clean or replace the upper element, then

repeat these instructions.

To remove the element from the tank in order to clean or

replace it:

1. Before beginning turn “OFF” the electric power supply

to the water heater.

2. Turn off the water supply to the water heater at the

water shutoff valve or water meter.

water heater drain valve. Open a nearby hot water

faucet which will relieve pressure in the water heater

and speed draining. Note: Only 30 gallon model is

all other models have a drain valve installed in the

cold water inlet line; see Typical Installation section.

HAZARD OF ELECTRICAL SHOCK! Before removing any

access panels or servicing the water heater, make sure the

LY INJURY, OR PROPERTY DAMAGE.

WARNING

The water passing out of the drain valve may be extremely

hot. To avoid being scalded, make sure all connections
