TO STOP THE APPLIANCE
For Short Periods; Set the Operating Switch (or programmer) to
OFF as indicated by the Demand light H going out.
For Long Periods; Set the Operating Switch (or programmer) to
OFF as indicated by the Demand light going out. Switch off the mains
electricity indicated by the Standby light G going out. Remove the
cabinet front panel by lifting off its mountings. Twist the grey gas
control knob clockwise (shown by an arrow) and release. To relight
follow the above instructions.
The facia mounted programmer will retain its settings for about
4 weeks after which it will return to the factory set programme. The
display will disappear after approx. 12 hours.
ELECTRICITY SUPPLY FAILURE
The appliance will not operate without an electricity supply.
Normal operation of the appliance will resume after the electricity
supply is restored.
OVERHEAT THERMOSTAT
Two overheat thermostats are fitted to the appliance which
interrupt the appliance operation in the event of overheating.
Thermostat E is reset manually. The second thermostat resets
automatically.
If the appliance fails to light, check that the overheat thermostat
has not operated by pressing the reset button E. If the overheat
thermostat stops the appliance again call a service engineer.
NOTE: If the electrical supply to the appliance is interrupted at
the isolation switch or a power failure occurs whilst the burner is
firing, the boiler will normally relight automatically when the power
supply is restored. However, depending upon circumstances it may be
necessary to reset the overheat thermostat before the appliance will
operate.
FLUE SPILLAGE DEVICE (O.F. ONLY)
The appliance is fitted with a device which detects the spillage of
combustion products from the draught diverter. In the event of the
flue becoming wholly or partially blocked this device will cut the gas
supply to the burner. The device automatically resets after a waiting
period of approximately 10 to 15 minutes. If the blockage remains the
appliance will relight briefly before the device operates again. Should
the problem persist consult your service engineer.
