28.0 TROUBLESHOOTING GUIDE
PROBLEM CORRECTIVE ACTION
Igniter sparks but pilot does not light • No gas to Pilot, check the gas line connections.
• Air not fully purged. Purge supply or wait longer.
• Spark grounding 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 assembly.
• Blocked pilot, clean out.
• Blocked lint gauze, clean.
• Hold control knob in for longer.
• 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 LIT.
• There is a draft (i.e. from window or door, etc.) disturbing the pilot. Remove
draft. u
• The ODS safety system may sense lack of oxygen. Turn off appliance. Call a
qualified service technician. Open windows and doors to provide ventilation to
the area. v
Igniter electrode at pilot does not spark • HT lead detached,refit.
• Check the spark gap (see Section 16.0).
• Faulty piezo unit, replace.
• Debris shorting out electrode, clean.
• Spark shorting to metalwork under tray, realign HT lead.
The burner stays on for a period of time,
then cuts off
• Loose or faulty thermocouple, rectify.
• Blocked pilot, clean out.
• Dirt or lint in pilot aeration hole or on the lint gauze, 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 LIT.
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 pipe-work or valve.
• Check all pipe-work are adequately sized.
• 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. Modifications are dangerous and
can have a serious unseen effect on safety. NEVER MODIFY OR BEND THE
THERMOCOUPLE TO MAKE THE PILOT STAY LIT.
Fireplace smells when first lit or in use • Newness smell from brand new appliance.
• Leakage occurring. Carry out leakage test and rectify any problems.
• Combustible materials used in incorrect positions.
• Unit may require a service to remove dust from catalysts.
u This appliance is equipped with a oxygen depletion monitoring safety device (ODS). If the appliance shuts down during use for no
apparent reason then several reasons may be suspected. If a door or window has been opened creating a draft, then pilot disturbance could
be the problem and removal of the draft should resolve this.
v If pilot disturbance is not the cause, then the ODS safety system sensing that there is a lack of oxygen. TURN THE APPLIANCE OFF,
call in your installer to check the appliance and ventilation. DO NOT allow the appliance to be used until the qualified service technician has
determined that the appliance is operating properly and adequate ventilation is being provided.
