Replacing the Thermocouple
1. Remove the Burner Door Assembly as directed
previously.
2. Remove the retainer clip from the back of the two
piece wire connector and remove the two piece wire
connector from the assembly (Figure 25).
3. Pull the thermocouple from the pilot assembly
(Figure 29).
IMPORTANT: Be careful not to bend or alter the position of
the pilot assembly components.
4. Push the new thermocouple through the holes in the
pilot bracket. Insert the thermocouple tube into the
holes provided in the pilot assembly until it clicks into
place. Leave a small straight section entering and
leaving the two piece wire connector section for easier
removal/service.
5. Position the new thermocouple through the opening of
the two piece wire connector (Figure 25). NOTE: The
pilot tube should be located at the top followed by the
igniter wire then the thermocouple.
6. See “Replacing the Burner Door Assembly” section.
Cleaning the Combustion Chamber
and Flame-trap
1. Follow procedure outlined in “Removing the Burner

have accumulated in the flame-trap.
3. Reassemble following the procedure under the
“Replacing the Burner Door Assembly” section.
External Inspection & Cleaning of the

to remove it. NOTE: If unable to inspect or clean the flame-
trap from underneath, follow the “Cleaning the Combustion
Chamber and Flame-trap” section instructions.
