SERVICING INSTRUCTIONS
As with all gas appliances the unit must be serviced at least once per year, preferably at
the beginning of the heating season.
All servicing must be carried out by a qualified
service person.
Before commencing any servicing, ensure that the gas is turned off to the appliance and
that the appliance is cool.
•
Cleaning – If required the casing should be wiped with a damp cloth in soapy
water. The glass may be cleaned with any non-abrasive cleaner such as ‘hob brite‘.
•
Lift the cast front and the decorative frame to remove. Unscrew the four nuts
holding the glass, remove and place thoughtfully to avoid damage or injury.
•
Remove the front and rear coal sets, clean the burner and associated parts using a
vacuum cleaner. Take particular care to remove all debris around the pilot light.
•
The logs and backing ‘brickwork’ contain refractory fibre (RCF). Excessive
exposure to these materials may cause temporary irritation to the eyes, skin and
respiratory tract; consequently, take care when handling these parts to ensure
that the release of dust is kept to a minimum. We recommend the use of a HEPA
filtered vacuum to remove any dust and soot accumulated in the heater before
and after working on it. When replacing these articles, they should 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.
•
Refit burner into chassis and reconnect to the gas supply. Test all joints for leaks.
•
Following the instructions (section 7), 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.
