Gas low pressure protection (Gas pressure switch MIN)

38.2 Configuring the gas pressure switch MIN

NOTICE:
If nominal supply pressure falls below 75%, the gas pressure switch MIN turns the burner off. Once pres-
sure rises again, the gas burner restarts automatically.

Configuration process: 
1) Gas burner runs at nominal supply pressure in position QB MAX.
2) Supply pressure is decreased to 75% via the ball valve.
3) The gas pressure switch MIN must switch off at that supply pressure. Adjust accordingly.

38.3 Installation type gas pressure switch MIN

The gas pressure switch MIN is located upstream of the gas pressure switch. The position of the gas pres-
sure switch MIN is defined in the gas ramp diagram.
