not be broken up, but sealed in heavy duty polythene bags labelled ‘RCF Waste’,
which may be disposed of at a tipping site licensed for industrial waste. Normal
hygiene rules of not smoking, eating or drinking in the work area should be
followed.
•
Disconnect the gas supply to the appliance. Undo the two nuts holding the burner
assembly in the chassis. Remove the burner tray and examine it for general
condition. Discolouration of the burner surface is normal.
•
Clean around the air inlet, removing all lint in the area of the injector and ensuring
the pilot light aeration hole and flame head are clean. Injectors
–
Only original
manufacturer’s injectors must be used. Identification is as follows: Natural Gas
(G20) - 92/180, Propane (G31) - 92/90 should the oxypilot system need to be
replaced, the original manufacturer’s parts must be used.
•
Controls – The GAS CONTROL IS FACTORY SET AND NORMALLY NEEDS NO
ADJUSTMENT. Check for smooth operation of the gas valve.
•
Remove all covers; check the tightness of the thermocouple connection into the
valve, the condition of the piezo and ignition leads.
•
Examine the fire casing, the firebox and catalytic converter for obvious signs of
damage or degradation.
•
Clean out any dirt or dust accumulated in the bottom of the fire.
•
Reassemble in reverse order.
•
Replace burner into chassis and reconnect to the gas supply.
•
Test all joints for leaks.
•
Following the manufacturer's instructions, re-lay the fuel bed and replace the glass.
•
Light the fire using the method in the instructions and ensure that the pilot lights
consistently and the pilot flame envelopes the thermocouple. The pilot should hold
in 10 seconds.
•
Turn control to main burner, this should light smoothly within 10 seconds. Ensure
the valve gives adequate turn down and the thermostat bulb reduces the burner
rate to off when heated. The gas manifold pressures are factory preset using highly
accurate equipment and may be observed in the pressure test point on the valve.
In the unlikely event of the pressure being incorrect it may be reset (refer to data
plate for details), using a manometer or other pressure testing equipment.
•
Locate thermostat bulb in a cool place away from the appliance and preferably
outside of any inglenooks, to ensure it is sensing room air temperature.
•
Run appliance for 15 minutes, ensuring burner flames settle evenly.
•
A combustion analysis check should then be carried out. Using an analyser to
BS7927, first zero the equipment and sample the entire width of the combustion
product outlet.
Ratio of CO/CO2 should be less than 0.002 within 30 minutes.
(20ppm CO per 1% CO2) A reading of CO in the room centre should give a rise of
less than 9ppm
over ambient, peak reading. The catalyst is unlikely to need
replacement during the life of the appliance but if the combustion is suspect,
disconnect the appliance and contact the manufacturer. See the additional
information on testing.
