B. SERVICING COMPONENTS BELOW THE BURNER ASSEMBLY
To remove trim, lift vertically to allow the formed tags in the rear of the trim to slide out of the notches in the
flanges of the box. (Assemble in the reverse sequence). Remove the coals, coal supports, burner inserts and front
simulated coal. To gain access to the components below the burner assembly it has to be removed from the Vent
Box by disconnecting the gas supply at the inlet elbow and unscrewing the two screws at the base of the fascia
panel. Where the supply is fed from the right hand side across the front of the appliance it will be necessary to
disconnect the supply from the isolation tap or restrictor elbow.
i) TO CLEAN OR REPLACE THE INJECTOR: Unscrew the compression nut connecting the gas supply to the
injector elbow while supporting the injector to prevent any distortion of the framework. Unscrew and remove the
gas supply tube from the gas control valve, hold the injector lock nut with a spanner and rotate the injector.
Replace in the reverse order.
ii) TO REPLACE THE GAS CONTROL / FSD: Disconnect the three gas pipes and the thermocouple from the
gas control. Pull the control knob from the spindle, unscrew the lock nut securing the front of the control valve
(niting plate assembly), and remove the gas control valve. Replace in the reverse order.
iii) TO REPLACE THE PIEZO IGNITER: Pull the igniter lead from the piezo igniter tab. Hold the piezo lock nut
and rotate the piezo to unscrew and remove. Replace in the reverse order.
iv) TO REPLACE THE OXY-PILOT ASSEMBLY: The assembly is not an item that can be serviced as part of its
calibration depends on the proximity of the spark electrode and thermocouple tip. The assembly can be replaced
by removing the tube nut and the tube from the base of the pilot, the thermocouple from the FSD, the igniter lead
and the two M4 screws securing the bracket to the framework. Replace in reverse order, the spark gap is shown in
figure 12.
v) PROTECTIVE SIDE PLATES; These stainless steel plates are pushed over the flanges of the fibre retaining
channels and can be replaced if required.
