the overheat neon light on the control box.
2. Hinge the lower door panel down (Fig 89).
3.
To reset the boiler
- Turn the boiler
thermostat control knob fully anti-clockwise to the
OFF position marked
‘
0
’
(Fig. 90). Wait ten
seconds, then turn the control knob clockwise to
the required thermostat setting. The red neon will
go out and the boiler will start automatically.
4. If the overheat cut-off operates repeatedly,
refer to the fault finding chart at the rear of this
booklet and investigate the cause.
