TO CHANGE THE COMPLETE PILOT UNIT ON THIS
APPLIANCE IN YEARS 2 AND 4.
7.1 Turn the gas supply off at the isolation device, remove the
door and place to one side, carefully remove the ceramic fuel
bed components.
7a. Pilot Burner Bracket
To remove the Pilot Burner Bracket:
7.2 First remove the electrode, pilot pipe and thermocouple
as described in the following sections.
7.3 Remove the 2 screws securing the bracket. The pilot burner
bracket can now be removed.
7.4 Replace in reverse order.
7b. Electrode
7.5 Pull the ignition lead off the electrode and undo the retaining
nut, see Diagram 23.
7.6 Replace with a new electrode. Do not over-tighten the nut;
this could break the component.
7.7 Replace the ignition lead by pushing the spade connector
onto the terminal (electrode).
7c. Pilot Injector
7.8 Undo the pilot pipe from the gas valve and from the
underside of the pilot burner, see Diagram 23.
7.9 Remove the pipe and the injector drops out from the burner.
7d. Thermocouple
7.10 Disconnect the thermocouple from the gas valve.
7.11 Undo the thermocouple nut in the back of the pilot bracket
half a turn. This releases the thermocouple.
7.12 When replacing with a new thermocouple, take care to bend
the new component to the same shape as the thermocouple
just removed.
7.13 To ret the thermocouple into the pilot bracket, ensure
it is pushed fully into the hole. There is a stop on the
thermocouple to set the height.
7.14 Lock the retaining nut just enough to grip the thermocouple.
7.15 Connect the thermocouple to the valve taking care not to
over-tighten.
