Detector Current; Removing Firing Head - Ecoflam Multicalor 1500.1 Mode D'emploi

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 minimum by
turning regulator D to position 1.
- Start the burner and keep in low flame running, while checking that combustion is cor-
rect. 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 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 burner 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.
