MAINTENANCE AND SERVICING
GENERAL
A.REMOVAL OF DEBRIS or SOOT DEPOSIT
Allow the appliance to cool for two to three hours before removing all of the coals and ceramic blocks for cleaning
purposes. Once all the ceramics are removed from the fire bed check that no debris is located in the burner slots
(both front & rear). If any debris is present it may easily be removed by using a small piece of thin cardboard to
ease out any foreign matter. Be sure to remove the cardboard after use. To ensure that the release of fibres from
these RCF articles is kept to a minimum, during installation and servicing we recommend that you use a HEPA
filtered vacuum to remove any dust and soot accumulated in and around the fire before and after working on the fire.
When replacing these articles we recommend that the replaced items are not broken up, but are sealed within heavy
duty polythene bags, clearly labelled as RCF waste. This is not classified as "hazardous waste" and may be disposed
of at a tipping site licensed for the disposal of industrial waste. Protective clothing is not required when handling
these articles, but we recommend you follow the normal hygiene rules of not smoking, eating or drinking in the
work area and always wash your hands before eating or drinking. Any sooty deposit on the thermocouple probe can
be cleaned off using a non-fluffy cloth.
* DO NOT USE ABRASIVE MATERIALS *
B.SERVICING COMPONENTS BELOW THE BURNER ASSEMBLY
Remove coals, coal supports, burner inserts and front simulated coal. To gain access to components below the
burner assembly it has to be removed from the case 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 fire, it will be necessary to disconnect the supply from the isolation tap/elbow.
i) TO CLEAN OR REPLACE THE INJECTOR: Unscrew the compression nut connecting the gas supply to the
elbow injector while supporting the injector. This is to prevent 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 reverse order.
ii) TO REPLACE THE GAS CONTROL VALVE: Disconnect the three gas pipes and the thermocouple from the
control. Pull off the knob and lay to one side. Undo the retaining nut at the front of the tap niting position to
withdraw the control from the mounting bracket. Replace in reverse order.
iii) TO REPLACE THE PIEZO IGNITER: Pull off the HT lead from the rear of the igniter. Retain the metal fixing
nut with one finger and rotate the body of the igniter to unscrew. Withdraw the igniter from the front. Replace in
reverse order and reconnect the HT lead.
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; 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. It is advisable to check joints for
leaks prior to refitting the burner unit into position. |
