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.
CALIBRATION OF MAIMUM GAS PRESSURE SWITCH (ON REQUEST)
The maximum gas pressure switch locks-out the burner if the gas pressure is higher than
the required level. Adjust the pressure at the combustion head 15% (natural gas)/10% (B/P)
higher than the rated output required at installation.
