Note:
The fully closed cam is factory set, and under normal
circumstances should not require further adjustment.
Operation of the low and high flame air switches is made by
manually adjustable cams. A setting scale is provided at the
end of the cam stack for guidance, while adjustments are
made using the screw adjusters situated within the cam disk
body (STM30 Q5), or with levers and fine setting screw
adjusters (STM30 B2).
