REMOVING THE FIREBOX
Remove the firetray as previously described. Uncoil the fixing kit cables from the rear of the firebox, remove the
screwed nipples and tensioning adjusters. The firebox can now be withdrawn from the opening and outwards
onto the protected hearth.
Inspect the fireplace opening for debris, and if excessive rectify the flue before proceeding further. Check the seal
around the fireframe and replace if necessary. Refitting of the firebox is described in the relevant section.
DISMANTLING THE BURNER TRAY
Remove the tray as previously described. The pilot unit can be removed by undoing 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. Clean the exterior of the pilot
assembly with a soft brush and blow through the flame ports on the pilot head. Check the aeration holes are free
from lint or dirt. The pilot assembly is a non-serviceable item, and should not be taken apart. The aeration hole
must be absolutely clear internally for proper operation. A thoroughly cleaned (inside and out) oxypilot will cure
a wide range of ignition faults. The injector can be removed from the base of the assembly with two spanners to
make cleaning the aeration hole out easier.
Remove the two tubing nuts on the ends of the gas pipe to the injector elbow. 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 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.
TROUBLESHOOTING GUIDE
Fire sparks but pilot does not light
No gas to fire, check isolators are open.
Pipework blockage, clean out.
Air not fully purged, repurge supply or wait longer.
Spark earthing to metal work, reset gap correctly.
Blocked pilot, clean out internally.
Pilot lights but then goes out
Severe restriction in gas supply, clear obstruction.
Faulty thermocouple, replace pilot unit.
Hold control knob in for longer.
Check control knob does not foul data plate.
Fire does not spark at pilot
HT lead detached, refit.
Spark gap too large or small, reset correctly.
Faulty piezo unit, replace.
Debris shorting out electrode, clean.
Fire runs for a time and then cuts off
Excessive room draught or flue pull, rectify.
Loose or faulty thermocouple, rectify.
ODS system in operation.
Firebox grommet seal not fitted, rectify.
Lint in pilot aeration hole, clean thoroughly internally
Pilot flame shrinks when fire is on high
Poor gas flow to fire, check pressure with fire on high.
If pressure is low, remove any restriction in pipework or valve.
Check all isolators are adequately sized and fully open.
Check meter pressure is adequate.
Air leak under base of firebox, rectify.
Lint in pilot aeration hole, clean thoroughly internally.
Fire smells when first lit or in use
Newness smell from brand new appliance.
Spillage occurring. Carry out spillage test and rectify any problems.
Low temperature sealants or combustible materials used in incorrect positions.
Air leak under base of firebox, rectify.
