ADJUSTMENT OF GAS MINIMUM PRESSURE SWITCH
Unscrew off and remove cover M. - Set regulator N to a value equal to 60% of gas nominal
feed pressure (i.e. for nat. gas nom. pressure = 20 mbar, set regulator to a value of 12 mbar;
for L.P.G. nom. pressure of G30/G31- 30/37 mbar, set regulator to a value of 18
mbar).Screw up cover M
ADJUSTMENT OF THE AIR PRESSURE SWITCH
Unscrew screws A and B and remove cover C.- Set the pressure switch to the mini-
mum by turning regulator D to position 1.
- Start the burner and keep in low flame running, while checking that combustion is
correct. Through a small cardboard, progressively obstruct the air intake until to
obtain a CO

increase of 0,5÷0,8% or else, if a pressure gauge is available, connected
to pressure port E, until reaching a pressure drop of 1 mbar (10 mm of W.G.). -
Slowly increase the adjustment value of the air pressure switch until to have the bur-
ner lockout. Remove the obstruction from the air intake, screw on the cover C and
start the burner by pressing the control box rearm button.
Note: The pressure measured at pressure port E must be within the limits of the
pressure switch working range. If not, loose the locking nut of screw F and gradually
turn the same: clockwise to reduce the pressure; counterclockwise to increase. At the
end tighten the locking nut.

The detector current is checked by inserting a microamme-
ter (scale 1000 µA - d.c.) in series with the uv cell..
The flame detector current has to been > 70 µA.
