Ensure that all external controls, e.g. room
thermostat, timer etc., are calling for heat. To
operate the pilot turn the thermostat knob to the
desired position. The pilot light (50/4E) or indicator
light (50/5) will illuminate once the pilot is lit. The
burner will also light shortly after the pilot has been
established. The pilot is intermittent and only lights
when there is a call for heat.
If the boiler cannot be lit by the above method
consult your Service Engineer.

required setting. The optimum boiler thermostat
setting depends upon type of system, external
controls and your requirements. Your Installer will
be able to advise you on this matter.
