To calculate the burner’s working output, in kW, proceed as follows:
- Check at the meter the quantity of supplied litres and the duration, in seconds, of the
reading, then calculate the burner’s output through the following formula:
CALCULATION OF WORKING OUTPUT OF THE BURNER
e x f = kW
s
e = Litres of gas
s = Time in seconds
G20 = 34,02
G25 = 29,25
G30 = 116
G31 = 88

STARTING-UP THE BURNER
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 (sealed, free from blocka-
ge, 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 power to the transformer and opens the gas valves. The flame must be
lit and stabilize within 3 seconds, which is the device's safety time limit. Check to ensure the flame is lit before placing
any control instrument in the flue. Adjust and check the gas flow necessary for the boiler at the meter. Adjust the air
flow according to the gas flow to obtain correct combustion.
IMPORTANT ADVICE
All adjustable parts must be fixed by the installer after making adjustments. Check flue combustion after each adjusti-
ment. The CO2values must be approx. 9.7 (G20) 9.6 (G25 11.7 (G30) 11.7 (G31) and the CO must be less than 75
ppm.

Installation must be carried out in compliance with the local provisions
The burners have been certified in combustion
chambers according to EN 676 standards.
Consult the burner manufacturer if the com-
bustion chamber of the boiler in which the
burner is to be installed has smaller dimen-
sions.

ADJUSTING THE AIR PRESSURE SWITCH
The air pressure switch must be adjusted so that an insufficient air flow does not allow
the CO value to exceed 1% in volume. After having adjusted the gas flow and obtained
optimum combustion (CO2= 9.5 to 9.8% and a CO value of less than 75 ppm), the air
pressure switch must be adjusted. Remove the cover with the burner operating, cover
the air intake progressively with a piece of cardboard to obtain a value of CO2= 10.8
(G20-G25)> 13 (G30-G31) and a CO value of less than 5,000 ppm. Adjust the air
pressure switch until the burner shuts down. Remove the cardboard from the air intake
and start up the burner again. Replace the cover.
ADJUSTING THE GAS PRESSURE SWITCH
Adjust the pressure switch to 50% of the rated pressure of the gas used.
RARED PRESSURE: G 20 = 20 mbar
G 25 = 25 mbar
G 30 = 29 mbar
G 31 = 37 mbar

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(Landis).
ADJUSTMENT AIR SERVOMOTOR ( SIEMENS SQN 75 )
Remove cover to enter the adjusting cams. Adjust cams through the suitable
key (on issue) and a screwdriver.
FOR THE ADJUSTEMENT OPERATE ON SERVOMOTOR CAMS
AND MAKE REFERENCE TO THE INDEX ON AIR DAMPER (SEE
Pic. A)
Description:
I – Adjusting cam (BLUE) for air damper position on burner’s shutdown
(totally close 0°).
II – Adusting cam (ORANGE) for ignition position and Low Flame
(adjust by the screwdriver).
III – Adjusting cam (RED) for High Flame position (max.output air damper
setting = 9).
IV – Adjusting cam (BLACK) to allow the opening of High flame solenoid
valve (cam position has to be between II and III).

MAINTENANCE
YEARLY INSPECTION
Periodic inspection of the burner (combustion head, electrodes, etc.) must be carried out by authorised per-
sonnel once or twice a year, depending of use. Before carrying out maintenance inspection on the burner, it
is advisable to check its general condition and carry out the following operations:
- Disconnect the burner from the power supply (remove the plug).
- Close the gas cock.
- Remove the burner cover, clean the fan and air intake.
- Clean the combustion head and check the position of the electrodes.
- Re-assemble the parts.
- Check the seal on the gas pipe fittings.
- Check the flue.
- Restart the burner.
- Check the combustion parameters (CO2= 9.5 to 9.8),(CO = less than 75 ppm)
BEFORE EACH INTERVENTION CHECK;
- That the system is supplied with power and the burner connected.
- That the gas pressure is correct and the gas cock open.
- That the control systems are correctly connected.
If all these conditions are present, start the burner by pressing the release button. Check the burner cycle.
THE BURNER WILL NOT START;
- Check the switch, thermostats, motor, gas pressure.
THE BURNER PREVENTILATES AND LOCKS AT THE END OF THE CYCLE:
- Check the air pressure and fan.
- Check the air pressure switch.
THE BURNER PREVENTILATES AND WILL NOT IGNITE:
- Check the assembly and position of electrodes.
- Check the ignition cable.
- Check the ignition transformer.
- Check the safety devices.
THE BURNER STARTS UP AND LOCKS AFTER THE SAFETY TIME LIMIT:
- Check that the phase and neutral wires are correctly connected.
- Check the gas electrovalves.
- Check the position of the detection electrode and its connection.
- Check the detection electrode.
- Check the safety devices.
THE BURNER STARTS UP AND LOCKS AFTER RUNNING FOR A FEW MINUTES.
- Check the pressure regulator and the gas filter.
- Check the gas pressure with an ammeter.
- Check the detection value (min 3 µA Landis).
