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 regula-
tor 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
DJUSTMENT OF THE AIR PRESSURE SWITCH
Unscrew screws A and B and remove cover C.- Set the pressure switch to the
minimum by turning regulator D to position 1.
- Start the burner and keep in low flame running, while checking that combu-
stion is correct. Through a small cardboard, progressively obstruct the air intake
until to obtain a CO2 increase of 0,5÷0,8% or else, if a pressure gauge is availa-
ble, 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 burner lockout. Remove the obstruction from the air intake,
screw on the cover C and start the burner by pressing the control box rearm but-
ton.
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 pressu-
re; counterclockwise to increase. At the end tighten the locking nut.

FLAME DETECTION SYSTEM CHECK
With the burner switched off, connect a DC microammeter with a 0÷50 or 0÷100 µA dial. When the burner is run-
ning, and is properly adjusted, the value read must be steady and never be smaller than 3 µA.
