TROUBLESHOOTING GUIDE

Fire sparks but pilot does not light No gas to fire:
Check if isolator valves are open.
Pipe work blockage: Clean out.
Air not fully purged: re-purge supply or wait.
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.
Blocked pilot: Clean out.
Hold control knob in for longer.
Check control knob does not foul data plate.
If the pilot does 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.
Never modify or bend the thermocouple to keep the pilot alight.
   
Fire does not spark at pilot Spark lead detached: Refit.
Check the spark gap (see section 5.2).
Faulty piezo unit: Replace.
Debris shorting out electrode: Clean.
Spark shorting to metal under tray: Realign spark lead.
   
Fire runs for a time and then cuts off Loose or faulty thermocouple: Rectify.
Blocked pilot: Clean out.
Dirt in the aeration hole: Clean thoroughly.
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. Never modify or bend the thermocouple to make the pilot stay alight.
   
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 restrictions in pipe work or valve.
Check all isolators are adequately sized and fully open.
Check meter pressure is adequate.
If the pilot will not stay lit there is a problem with dirt, the gas Supply, or the thermocouple needs replacement.
Check the length of the gasline, if it is to long you might have Pressure drop.
   
Fire smells when first lit or in use Newness smell from brand-new appliance
Leakage occurring: Carry out leakage test and rectifyproblems.
Combustible materials used in incorrect positions.
