If fitting a new tap, remove the hexagonal nut at the mounting bracket end of the old
tap and fit to the replacement tap. Refit in the reverse order. When refitting, make sure
that the tap spindle is in the correct relationship relative to the control pivot bracket.
Rotate the pivot bracket fully clockwise. The tap spindle should “bottom out” (i.e. the tap
should be fully open) after the pivot bracket has actuated the ignition microswitch but
before it has pushed the microswitch leaf against the microswitch body.
When refitting the thermocouple and interrupter block, make sure that the microswitch
wires are properly secured to give a good electrical contact.
