Service and Maintenance (cont’d)
CAUTION
Never use this water heater unless it is completely
full of water. To prevent damage to the tank and
heating element, the tank must be filled with water.
Water must flow from the hot water faucet before
turning “ON” power.
14. Check element for water leaks. If leakage occurs, tighten
element or repeat steps 2 and 3, remove element and
reposition gasket. Then repeat steps 10 through 14.
15. Reconnect the two wires to the element and then check
to make sure the thermostat remains firmly against the
surface of the tank.
10. A new gasket should be used in all cases to prevent a pos-
sible water leak. (See Element Gasket in the Repair Parts
Chart). Place the new element gasket on the thread side
of the cleaned or new element and screw into tank, secur-
ing tightly using an element wrench.
11. Close the water heater drain valve by turning the handle
to the right (clockwise). The drain valve is on the lower
front of the water heater.
12. Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
13. To insure complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run
until a constant flow is obtained. This will let air out of
the water heater and the piping.
7. Disconnect the two wires on the element and unscrew the
old element from the tank.
6. Lift out the tab as shown to unclip the terminal cover from
the thermostat. The terminal cover can now be removed
from the thermostat.
8. Clean the area around the element opening. Remove any
sediment from or around the element opening and inside
the tank.
9. If you are cleaning the element you have removed, do so
by scraping or soaking in vinegar or a de-liming solution.
WARNING
Replacement elements must (1) be the same volt-
age and (2) no greater wattage than listed on the
model rating plate affixed to the water heater.
Lift out tab to unclip
