PRESSURE SWITCH TYPE: GW 150 A5
CALIBRATION OF AIR PRESSURE SWITCH
The air pressure switch places the burner in safety mode or shuts it down should there be a drop in combustion
air pressure. It will be calibrated at a pressure below 1st stage rated-flow on-burner air pressure, checking
that CO values do not exceed 10,000 p.p.m..
CALIBRATION OF MINIMUM GAS PRESSURE SWITCH
The minimum gas pressure switch serves to prevent the burner from being started up or to shut it down if the
gas pressure falls below the minimum required level. This setting should be 40% lower than the gas pressure
obtained with the burner operating at maximum delivery.
