Fire sparks but pilot does not light
•
No gas to fire, check isolators are open and gas supply is on.
•
Pipework blockage, clean out.
•
Air not fully purged, re purge supply or wait longer.
•
Spark earthing to metalwork, 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.
•
Blocked pilot, clean out.
•
Blocked lint gauze, clean.
•
Hold control knob in for longer.
•
Check control knob does not foul indicator plate.
•
If the pilot will not stay lit there could be a problem with contamination of the gas
supply, drafts, room size and/or ventilation or the thermocouple needs replacement.
Modifications are dangerous and can have a serious unseen effect on safety.
NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT.

Modifications are dangerous and can have a serious unseen effect on safety.
NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT.
Pilot flame shrinks when
•
Poor gas flow to fire, check pressure with fire on high.
fire is 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.
•
If the pilot will not stay lit there could be a problem with contamination of the gas
supply, drafts, room size and/or ventilation or the thermocouple needs replacement.
Modifications are dangerous and can have a serious unseen effect on safety.
NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT.
Fire smells when first lit or in use
•
Newness smell from brand new appliance.
•
Leakage occurring. Carry out leakage test and rectify any problems.
