8.1 Operation
1. The overheat cut-off device is of the manual
reset type and therefore it is important that the
user knows how to reset the control should it
ever cut out.
NOTE: Cut-out is indicated by illumination of
the neon light on the control box.
2. Remove the lower door panel by following the
sequence of diagrams (Fig 87).
3. To reset the boiler - Turn the boiler
thermostat control knob fully anti-clockwise to the
OFF position marked ‘0’ (Fig. 88). Wait ten
seconds, turn the control knob clockwise to the
required thermostat setting, the red neon goes
out, the boiler will start automatically.
4. No adjustment to the gas controls or main
thermostat are required.
5. If the overheat thermostat drops out
repeatedly, refer to the fault finding chart at the
rear of this booklet or consult a competent
service engineer.
