Safety Device
The boiler is fitted with a flue blockage safety device which will
shut it down if there is a problem with the chimney. This device
is NOT a substitute for an independently mounted Carbon
Monoxide detector.
The safety device is reset, after three minutes, by pushing in the
button shown in diagram 2.
Shut down can occur during certain climate conditioned, but if
it recurs the chimney flue and air inlet into the room must be
checked and any problems found corrected by a competent
person, before the boiler is used again.
Any problems found must be put right, by a competent person,
before the boiler is used again.
To Turn the Boiler On
Turn the electrical supply on to the boiler and check that any
remote controls are set to your requirements (refer to
manufacturer’s instructions supplied with these items).
WARNING. If the pilot flame goes out either intentionally or by
accident, no attempt should be made to relight it for at least
three minutes.
Slide to controls cover off and clear.
Identify the controls by reference to diagram 2.
Switch off the electrical supply to the boiler.
Check that the flue blockage safety device has not operated,
that is, the button is in. Refer to Safety Device instructions.

To Turn the Boiler Off
For short periods, turn the thermostat knob fully clockwise to “O”
Off. To relight, turn thermostat knob anticlockwise to any
position between “MIN” and “MAX”.
For longer periods, turn the thermostat knob fully clockwise to
“O” Off. Slide the gas control button “D” inward and release, see
diagram 2. Switch off the electrical supply to the boiler.
To relight, follow the full lighting sequence given above.
Protection Against Freezing
If the boiler is to be out of use for any long period of time during
severe weather condition we recommend that the whole system,
including the boiler, be drained off to avoid the risk of freezing
up. Make sure that, if fitted, the immersion heater in the cylinder
is switched off.
The serial number and GC number of the boiler can be found on
the data label.
