1. Loosen the bulkhead nut.

3. Remove the screws and washers from the plastic bracket.
4. Rotate the micro flame photometric detector (µFPD) burner around the bulkhead
nut until there is enough room to remove the igniter/thermocouple assembly.
5. Loosen the nut; then slide the igniter/thermocouple assembly and ferrule (not
shown here) out of the µFPD burner through the fitting.
6. Slide the bulkhead nut and a new ferrule on the new igniter/thermocouple
assembly. Then slide the µFPD burner through the fitting.
7. Align the black plastic edge of the igniter with the end of the nut and gradually
tighten the nut to the fitting. Keep pushing the igniter toward the burner while
tightening the nut. The back edge has to be flush with the end of nut when secured.
Tighten the nut to 4 in.-lb.
