C. Heating Element Replacement Procedure
STEP #1 - Turn o power to the water heater. Use a Phillips
Head screwdriver to remove the wires from the element.
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.
Failure to disconnect the power from the water heater before
attempting heating element replacement will result in property
damage, severe personal injury, or death due to electric shock.
STEP #2 - Run hot water at a faucet in the system. When it
runs cold, shut o the faucet. Then shut o water at the main
cold water inlet or, if possible, valve o the water heater from
the system. Drain the water from the system, or just the water
heater if it can be isolated from the system.
Completely drain the water heater before removing and
replacing a heating element or elements. Failure to do so will
result in a leakage of water and property damage, and could
possibly result in moderate to severe personal injury or death.
Water drained from the water heater may be scalding hot. Take
care to avoid scalding. Wear gloves and safety glasses, and
direct water to a safe drainage location. Failure to comply with
this warning could result in property damage, severe personal
injury, or death.
DO NOT replace heating element with a generic heating
element. Only HTP heating elements are approved for use with
this water heater. Failure to follow this warning will result in
premature product failure and VOID the warranty.
Step #3 - Remove the element with a 1 1/2” socket wrench or
element tool.
Step #4 - Ensure thread and opening are completely free of
debris. Use a nylon brush to clear away any debris.
Step #5 - Put a small amount of NSF approved lubricant and
sealant on the O-Ring.
Step #6 - Screw the element clockwise into the tank, and
tighten with the 1 1/2” socket wrench or element tool. Be sure
O-ring seats properly.
