16.00 Fault finding
Operating errors can be rectified by the User by following the User Instructions and suggestions below.
Operating faults may have to be diagnosed and rectified by a qualified gas engineer. If the burner assembly
requires to be disconnected from the gas supply, always use a qualified engineer.
IF THE FIRE ‘WON’T LIGHT’ – first ensure the gas and electrical supplies are switched ON and any batteries
(burner or remote handset) have a full charge:
If the PILOT FLAME will not light:
1. When operating the handset (Section 14.0) do you hear a constant clicking sound at the pilot location?
If not, check that there is 6V & 1200mAmp available from the transformer, using a multimeter. If no
voltage, check the 240V supply, consumer unit - or replace the transformer. Alternatively, test the
transformer by disconnecting it from the black plastic control box (Receiver Unit - see Section 2.1) fit 4 x AA
batteries and test the ignition sequence again. DO NOT use batteries and a working transformer together.
2. If you can hear clicking, but the pilot doesn’t light:
Has the installer purged the gas supply? There may be air in the gas line. Check that a piece of Crystalight or
garden debris is not obstructing the pilot flame.
3. When correctly operating the handset for a second or third time, have you waited a few seconds before
attempting re-ignition?
A safety system will not allow igntion immediately. Wait at least 60-120 seconds between lighting attempts.
4. If you cannot hear the ignition clicking when correctly operating the handset, can you hear the motorised
gas valve re-setting?
If not, you can reset the ignition process, electronic controls and motorised gas valve by
turning off the 240V supply, waiting 30 seconds & switching on the 240V supply again (or an INSTALLER
can reset the Receiver Unit having disassembled the control box).
5. If you can hear the ignition process, is the pilot alight, but can’t been seen due to direct sunlight?
CAREFULLY feel for warmth from the pilot flame by holding your hand well above the pilot device.
6. If the pilot flame lights, but does not stay alight:
Check that a piece of Crystalight gas media or garden debris is not obstructing the pilot flame. INSTALLERS
ONLY: Check the pilot flame is impinging on the thermocouple. Check the thermocouple is hand-tight plus a
quarter turn on the gas valve. An engineer can verify the electrical output of the thermocouple.
7. If the pilot flame lights, but the MAIN BURNER does not:
Does the pilot extinguish when the main burner lights?
If yes, can you hear the gas valve resetting? You can reset the electronic controls and motorised gas valve by
turning of the 240V supply, waiting 30 seconds and switching on the 240V supply again. INSTALLER Have
you checked operating & burner pressures? See 1.2 Technical Data for the correct settings.
8. If the pilot flame and main burner lights, but the main burner will not stay alight:
You can reset the electronic controls and motorised gas valve by turning off the 240V supply, waiting 30
seconds and switching on the 240V supply again. INSTALLER check the thermocouple output and connec-
tions.
If none of the above helps, in the UK please call 0207 183 1806 or 0790 223731 before leaving site.
In Ireland or mainland Europe please call the supplier. If in doubt, always consult a qualified, experienced
engineer.
