D. Heating Element Replacement Procedure
If heating elements need replacement, it is very important to use the
same voltage, wattage, and construction. The element sheath must
be incoloy and the hex plug must be made of stainless steel.
NOTE:
If the lower heating element needs replacement, follow the
instructions to remove the lock box in, “Adjust the Lower Thermostat”.
