MAINTENANCE & SERVICING GENERAL A. Removal of Debris or Soot Deposits; Allow the appliance to cool for one hour before removing all the coals and coal bed components for cleaning purposes. Once all the components have been removed from the fire bed check that no debris has become lodged in the burner ports (both front and rear). If any debris is present it may be easily removed with a thin piece of card or similar to ease out any foreign matter. Any soot deposited on the coals etc; may be removed by using a soft brush or with the careful use of a vacuum cleaner. Any soot deposits may be removed from either the Thermocouple or Electrode tips with a soft cloth, do not use abrasive materials.
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. (re-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 frame work. 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 CLEAN OR REPLACE THE OXY-PILOT ASSEMBLY (including electrode and thermocouple): Unscrew the self -tap screw securing the clamp bracket. Undo the supply tube nut at the gas connection to the pilot taking care not to lose the filter trapped between the olive and recess in the base of the pilot base, (see Fig.10) withdraw the oxy-pilot assembly. Clean off any lint or fluff taking care to avoid damage. The individual parts cannot be changed separately as the assembly is precision built. Reassemble in reverse order ensuring that the filter is fitted in place. It is advisable to check joints for leaks prior to refitting the burner unit into position.
