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 pres-
sure. 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.
CHECKING CONTROL BOX IONIZATION CURRENT
The minimum value of 3
A should be observed,
and large oscillations are to be avoided.
