7) Assemble New Pilot Assembly
• A colored line on the top of the pilot indicates the type of fuel used. A BLACK line is used
on a natural gas pilot, whereas a RED line is used on a propane pilot. Both pilots are
included in this kit. Ensure that the correct pilot is used for the unit.
• Unscrew the nut on the end of the selected pilot to release the nut, the ferrule and the
orifice. Install the nut and the ferrule on one end of the flex tube.
• Place the orifice back into the pilot and screw on the flex tube.
• Push the thermocouple all the way into its slot on the pilot.
Finished Pilot Assembly
Left: Correctly assembled pilot with thermocouple pushed all the way through; thermocouple taller
than hood, no excess length sticking out from bottom
Right: Incorrect assembly, pilot not pushed all the way through; thermocouple shorter or equal in
height to hood, excess length sticking out from bottom
