To Remove The Gas Flow Rate Controller; To Replace The Burner - Valor 961 Installation And Owner's Manual

INSTALLER GUIDE
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.
