SERVICING
Isolate the fire from the gas supply. Ensure that the fire is fully cold before attempting service.
A suggested procedure for servicing is detailed below.
1. Lay out the dustsheet and tools.
2. Remove the decorative frame/glass facia assembly. Removal is reverse of section 8.4.
3. Remove the glass door assembly (4 screws) and clean carefully.
4. Inspect the burner and the catalyst and clean if necessary with a soft brush.
5. Disconnect the gas supply.
6. Detatch the burner front cover plate by removal of the four retaining screws. Undo the four
screws retaining the burner support brackets to the base and rear of the firebox. Remove the
control knob and spindle assembly from the valve by removal of the spindle retaining clip.
7. Remove the burner unit, strip off the burner pipes and clean thoroughly.
8. Clean the in-line restrictor, pilot assembly and the burner tube. Do not attempt to remove the
pilot injector as this can cause damage.
9. Re-assemble components.
10. Turn on the gas supply and leak test. Check pilot and burner for good ignition.
11. Refit the glass door assembly, ensuring correct orientation and a good seal.
12. Refit the decorative facia/frame assembly as detailed in section 8.4.
13. Check the purpose provided ventilation is un-obstructed.
14. Light the fire and test setting pressures.
15. Check safe operation of the appliance.
For specific servicing instructions, see relevant sections.
SERVICING THE BURNER UNIT AND GAS ASSEMBLY
10.1
Firstly, remove the decorative frame/glass facia assembly as described in section 8.4. Remove the inner
glass panel, and disconnect the gas connection inside appliance. The gas connections to the gas valve can
now be released. Detatch the burner front cover plate by removal of the four retaining screws. Undo the
four screws retaining the burner support brackets to the base and rear of the firebox, and remove the con-
trol knob and spindle assembly by removal of the spindle retaining clip. The burner may now be removed.
Remove the pilot and main burner pipes and blow through to dislodge any debris. Now remove the restric-
tor elbow and blow through to make sure it is entirely clear.
Unclip the pilot lint gauze and clean with a soft brush. 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 can be removed if required by disconnecting the electrode HT lead, gas pipe and
unscrewing the mounting screws and lifting away.
The pilot assembly is a non-serviceable item and should not be taken apart. Aeration holes must be
absolutely clear internally for proper operation. NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE
THE PILOT STAY ALIGHT. Modifications are dangerous and can have serious unseen effects on safety. If
the pilot will not stay lit there is a problem with dirt, the gas supply to it, or the thermocouple needs
replacement.
The gas valve is a non-serviceable item. If this needs replacement, remove M4 securing screw holding the
valve in place, remove all pipe unions, electrode lead, thermocouple lead and then the complete valve.
Replacement must be original manufacturers parts. Re-assembly is the reverse of removal. Ensure setting
pressures are as stated in Section 2; Appliance Data.
10.2
PILOT ASSEMBLY
Clean the pilot assembly with a soft brush and blow through. Check the aeration holes are free of any dirt
or lint. Clean thoroughly internally, 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 dismantle the pilot injector.
The unit is factory set and the only check necessary is to ensure the spark gap is correct. See specifica-
tions for gas setting.
NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT. If the pilot will not
stay lit there is a problem with dirt, the gas supply, or the thermocouple needs replacement. Modifications
are dangerous and can have a serious unseen effect on safety and therefore MUST not be done.
Replacements must be original manufacturers parts. Re-assemble in the reverse of removal. Ensure setting
pressures are as stated in Section 2; Appliance Data.
