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/down for longer.
• Slide control models only : Ensure that the slide control knob is pushed down fully.
• 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 does not spark at pilot
• HT lead detached, refit.
• Slide control models only - replace battery. See section 9.1 of the user instructions.
• Check the spark gap (see section 16.4).
• Faulty piezo unit, replace.

• 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.
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.
• Firebox grommet seal missing, rectify.
• 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.
• 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.
