Service and Maintenance (cont'd)
10. If you are cleaning the element you have removed, do so
by scraping or soaking in vinegar or a de-liming solution.
16. Reconnect the two wires to the element and then check
to make sure the thermostat remains firmly against the
surface of the tank.
__________________ A 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.
11. 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.
12. 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.
13. 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.
14. 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.
A 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.
IS. Check element for water leaks. If leakage occurs, tighten
element or repeat steps 2 and 3, remove element and
reposition gasket. Then repeat steps 11 through 15.
17. Replace terminal cover on thermostat and fold insulation
back over the element making sure that the locking tabs
on the terminal cover are in place.
18. Fold the insulation back in place so that it completely cov­
ers the thermostat and element.
