SLOW IGNITION ADJUSTMENT
This is a slow ignition regulator whose trimmer is factory set to the
minimum.
For adjustment proceed as follows:
if turned clockwise the gas pressure at the burner increases on ignition
while turning counter-clockwise decreases the gas pressure.
ANTI CYCLING DEVICE
This allows the various ignitions to be delayed once the boiler has
reached the optimum temperature.
The time range goes from 0 up to 7.5 minutes.
