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
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 combustion 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 available, connected to pressure port E, until rea-
ching 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; coun-
terclockwise to increase. At the end tighten the locking nut.
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 1,5 µA.
The burners are produced with connections suitable for power supply 400 V three-phase.
The burners with electric motors of an output lower or equal to 7,5 kW can be adapted to 220-230 V (please follow the
instructions on the backside); motors with higher output can only work 380-400 V three-phase.
In case of request of burners different from the above mentioned standard, it is recommended to make specific mention
in the order.
Instructions: how to adapt electric motors of an output lower or equal to 7,5 kW to 220-230 V power supply
It is possible to change the voltage of the burner by operating as follows:
1. change the connection inside the electric box of the motor, from star to delta (see picture);
2. change the setting of the thermal relay, referring to the absorption values indicated in the
motor nameplate. If necessary, replace the thermal relay with another one of suitable scale.
This operation is not possible on motors above 7.5 kW.
For more information, please contact the Ecoflam staff.
