WARNING
Do not bend the gas valve connections too far; doing so may result in damage.
Remove the outer door from around the burner tubing at the base of the water heater. Remove the Piezo
igniter (with the orange wire) from the gas valve by sliding it back toward the tank (leave the orange wire in
the inner door assembly).
Remove the 3/8” nuts, holding the inner door and white gasket in place. Place some protection such as
newspaper to protect the floor from debris. Carefully remove the burner from the combustion chamber.
There may be soot or other materials collected on the top of the main burner; try not to dump any debris off
of the burner until it and the inner door have been removed from the water heater.
TAKE CARE NOT TO DAMAGE THE WHITE GASKET ON THE INSIDE OF THE INNER DOOR.
Inspect the radiation shield (thin circular metal sheet under the burner and above the flame arrestor). If any
of the sides of the radiation shield are touching the base (disrupting air flow), small feet can be obtained
free of charge by contacting our call center at 800-365-4054 and requesting them.
Vacuum the main assembly and pilot burner assembly. Vacuum the top of the radiation shield located
inside the burner chamber. Use the vacuum drapery brush attachment to clean the inside of the combustion
chamber and the exposed area of the flame arrestor. Use the crevice tool to vacuum under the radiation
shield as much as possible without bending the shield upward more than one inch or so.
Re-insert the burner taking care that the main burner tube is seated in the burner positioning bracket.
Carefully reposition the inner door w/gasket over the bolts on the combustion chamber. Do not tighten the
nuts down until the main burner, pilot burner, and thermocouple are attached and tightened. Make sure that
the white fibrous door gasket is not folded over and protrudes out from the inner door in all directions. Then
tighten the 3/8” nuts to hold the inner door in place.
Check the gas connections for proper fitting and then light the pilot, following the directions on the side of
the water heater. Once the pilot is lit, turn the valve to the “ON” position and ignite the main flame. Brush
soapy water on the gas connections and look for bubbling. This is an indication of a gas leak. If bubbles
appear, shut off gas supply and check fittings. Re-light the pilot and check for leaks again, repeating the
soapy water solution method.
Important Service Reminder
Any time service is performed on C3 TECHNOLOGY product the Five Point Inner Door Seal Inspection
outlined in the Sealed Combustion Chamber section should be performed and the LDO Screen (s) should
be inspected for proper installation (arrows up) and cleaned before leaving.
