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 set-
ting should be 40% lower than the gas pressure obtained with the burner operating at
maximum delivery..
