CATALYST (continued)

Now divide the concentration of carbon monoxide (CO) expressed in percent by the concentration of carbon diox-
ide (CO2) to obtain the appliance combustion ratio.

The combustion ratio of the gasses emitted by the catalytic convertor should not exceed 0.0015.

If replacing, firstly, remove the decorative fireframe as described in section 8.4.The catalyst is located on the top of
the internal firebox and can be removed be unscrewing the retaining nuts securing the clamping plate. Remove the
catalyst and its seal and discard. Refit a new catalyst and seals in reverse order, ensure the catalyst and door have a
good seals.

TESTING FOR FIREBOX LEAKAGE

Appliances that are several years old or have been extensively dismantled should be checked for soundness. It is

important that all the products of combustion pass through the catalytic converter at the top of the firebox

before leaving the appliance.The firebox is heated by lighting for a few minutes to provide a flow through the fire-

box.The burner is then shut off and a smoke pellet or match introduced at the base of the fire underneath the

burner tray. Large quantities of smoke will emerge from the top of the appliance, but none should emerge from

the joints or gasket faces, especially around the door. It is important to note that the appliance can never be

expected to be 100% smoke tight and small quantities of smoke may be seen in corners of joints and gasket faces

etc without affecting safety when the fire is in operation.

TROUBLESHOOTING GUIDE

Fire sparks but pilot does not light

No gas to fire, check isolators are open.

Pipe work blockage, clean out.

Air not fully purged, re purge supply or wait longer.

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.

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 is a problem with dirt, the gas sup-

ply, 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 8.2).

Faulty piezo unit, replace.

Debris shorting out electrode, clean.

Spark shorting to metalwork under tray, realign HT lead.

Fire runs for a time and 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 sup-

ply, 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.

If the pilot will not stay lit there is a problem with dirt, the gas sup-

ply, 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.

Combustible materials used in incorrect positions.
