Combustion Adjustment - Ecoflam BLU 3000.1 PR Manual De Uso

B LB 382 BLU 3000.1 - 4000.1 PR/MD
WARNING: In order to have a correct combustion and thermal output adjustments, these must be carried out together
with a combustion analysis, to be executed through suitable devices, taking care that the values are the correct ones and
are in accordance with the local safety regulations. The adjustments must be carried out by qualified and skilled techni-
cians authorised by Ecoflam S.p.A.
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.
