NOTE:
The low and high gas pressure switches should be set just above and below the safe operating range of
gas inlet pressures respectively. This should be individually determined on each installation. Typically this
would be 50% of the running pressure for the low gas pressure switch and 125% of the operating
pressure for the high gas pressure switch.
