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,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 does not spark at pilot • HT lead detached, refit.
• Check the spark gap (see section 12.3).
• Faulty piezo unit, replace.
• Debris shorting out electrode, clean.

• If the pilot will not stay lit there could be a problem with contamination of the
gas supply, drafts, 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.
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.
• Firebox grommet seal missing, rectify.
• If the pilot will not stay lit there could be a problem with contamination of the
gas supply, drafts, 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.
• Spillage occurring. Carry out Spillage test and rectify any problems.
• Combustible materials used in incorrect positions.
• Firebox grommet seal missing, rectify.
• Other airborne contaminants such as dust, tobacco smoke, paint vapours.
