- Air pressure switch adjustment - Setting gas pressostat

Air pressure switch calibration
The air pressure switch is provided for
monitoring the pressure of the
combustion air fan.
Unscrew screws A and B and remove
cover C. After the air and gas setting you
have to calibrate the air switch with the
burner working on the low flame by slowly
turning the relative knob clockwise until the
burner locks out. Read the value and then
decrease it by 15%.
Min gas pressure switch
The gas pressure switch has the function
to check that the gas pressure before the
gas valve does have the minimum
pressure to make the burner running
correctly. Unscrew off and remove cover
M. - Set knob N to a value equal to 60% of
gas nominal feed pressure (i.e. for natural
gas nom. pressure = 20 mbar, set knob to
a value of 12 mbar; for LPG nom. pressure
of G31- 30/37 mbar, set knob to a value of
18 mbar). Screw up cover M.
