SETTING THE FIRING HEAD
The firing head position adjustment is made in order to obtain the best combustion efficiency. When used with mini-
mum outputs the firing head is adjusted in rear position. With high output, the firing head is adjusted in forward posi-
tion. Adjustment: - Loosen screw A through a suitable Allen key. - By a screwdriver act on the hex. head screw B until
is reached the desired position. - Tighten screw A

REMOVING THE BLAST TUBE
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 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 reaching a pressure drop of 1 mbar (10 mm of W.G.). - Slowly increase the adjust-
ment 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 running,
and is properly adjusted, the value read must be steady and
never be smaller than 3 µA.

- Important to obtain the right adjustment of the combustion and thermal capacity it is important to analyze the reducts of combustion with the aid of suitable instruments the combustion and thermal capacity adjustment is done simultaneously together with the analysis of the products of combustion making sure that the measured values are sui table and that they comply with current safety standards on this matter please refer to the table and figure below these operations must be done by professionally qualified technicians 11

- Once connected the burner to the gas pipe make sure that there are no leakages air bleed the pipe through the pressure gauge fixing point and check the pressure with a pressure gauge turn the thermostats to the desired temperature preliminary checks before starting up the boiler check the following gas type and feed pressure gas valves closed the seals in the pipe fittings gas pipe breather and input pressure that the cable complies with the diagram and the phase and neutral wires correspond that the burner shuts down when the boiler thermostat opens the seal of the boiler furnace which prevents air from entering the seal on the flue boiler pipe fitting the condition of the flue sea led free from blockage etc if all these conditions are present start the burner the control device starts the motor to carry out prewashing of the combustion chamber during this prewash period about 30 seconds the device checks that air pressure is correct via the air pressure switch at the end it supplies 11
- Once connected the burner to the gas pipeline it is necessary to control that this last is perfectly sealed also verify that the chimney is not obstructed open the gas cock and carefully bleed the piping through the pressure gauge connector then check the pressure value trough a suitable gauge power on the system and adjust the thermostats to the desired temperature when thermostats close the sealing control device runs a seal test of valves at the end of the test the bur ner will be enabled to run the start up sequence 11
