Minimum gas pressure pressure switch
The gas minimum pressure pressure switch prevents burner start-up of stops it if it is functioning. If the gas pres
sure is not the minimum envisioned, it must be calibrated at 40% lower than the value of the gas pressure, which
functions with maximum flow rate.

Adjust gas pressure leak test
The gas pressure control must be set at about 2 / 3 of the inlet gas pressure.

Air pressure switch regulation
The air pressure switch has the task of putting the burner into safety or block conditions if the combustion air pres
sure is missing. This will be calibrated lower than the air pressure value at the burner when this is at nominal flow
rate with 1st flame functioning, verifying that the value of CO does not exceed the value of 10.000 p.p.m.
