For specific servicing instructions, see the relevant sections.
CLEANING TTHE C
CERAMIC PPARTS
Remove the firefront casting and place to one side. Remove the ceramic components. Gently clean in the open air. Be careful not to create
dust from the coals. Where necessary replace damaged components with genuine spares. Seal scrap ceramic components in plastic bags
and dispose at proper refuse sites as directed.
Re-fit the coals by referring to the relevant section of these instructions.
REMOVING THE BURNER TRAY
Remove the decorative front. Remove the ceramics and the data/control plate and place safely aside.
Remove the two screws securing the tray legs to the firebox. Pull tray forward slightly and lift away.
Refitting is the reverse of above, being sure to engage the tray location lugs on the shelf at the rear of the firebox.
DISMANTLING TTHE BBURNER TTRAY
Remove the tray as previously described.
The pilot unit can be removed by withdrawing the tubing nut, the thermocouple nut on the rear of the valve, and the two securing screws,
and lifting away. Remove the tubing nut from the valve end of the pilot pipe, and blow through to dislodge any debris.
Remove the two tubing nuts on the ends of the gas pipe to the injector elbow and blow clear. Release the screw through the supporting leg
and lift assembly clear. The injector pipe can now be checked for debris. Remove the nut retaining the injector elbow. Blow through the elbow
to remove any debris.
The valve is not field serviceable, apart from the pilot filter. Remove the control knob by pulling it forwards, then remove the largest of the
three screws on the face of the valve. Slide the filter out and clean away any debris that may have accumulated. The filter element should also
be blown clean. This component should not require replacement, however if signs of deterioration are evident then a genuine spare part must
be used. If a large amount of debris is present in the filter then the pipework and control should be thoroughly cleaned before re-assembly.
PILOT ASSEMBLY
Remove the burner tray as in relevant section and pilot unit as described.
Clean the pilot assembly with a soft brush and blow through. Check the aeration holes are free of any dirt or lint. Clean thoroughly internal-
ly, the connection can be removed from the base of the pilot unit using two spanners to make cleaning easier. Do not damage or try to
remove the pilot injector. The unit is factory set and the only check necessary is to ensure the spark gap is correct. See specifications for
gap setting.
REMOVING TTHE FFIREBOX
Remove the burner tray as described previously.
Protect the hearth from potential damage. Unroll the coiled tensioner cables from the rear of the firebox. Remove the securing nipples and
tensioner adjusters. The firebox is now released from the opening and can be slid outward onto the hearth. Inspect the fireplace opening
for debris and if excessive rectify the flue before proceeding further. Check the seal around the fireframe and if necessary replace. Refitting
of the firebox is as described in the fitting section of these instructions.
