Heating Elements
To replace heating elements, disconnect power to the water heater, drain
tank and replace element. To remove a heating element, use a 1 1/2” screw
type element wrench that is usually available at places where plumbing
supplies can be obtained.
Do not over-tighten the new element, as this will
cause distortion in the new element gasket. Once the element has been
replaced, follow the instructions “To Fill The Water Heater”. It is imperative
that the water heater is filled with water before the power is restored to the
heating elements.

Multiply kW input by 3,412 to determine BTU input:
Example: 54kW x 3412 = 184,248 BTU’s
Recovery Computation Formula
GPH= (watts x 3.412) / (8.25 x °Temp. Rise)
