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 CO values must be approx. 9.7 (G20) 9.6 (G25 11.7 (13B) 11.7 (13P) axld the CO must be less than 75
2
ppm.
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:
Installation must be carried out in compliance with the local provisions

CALCULATION OF WORKING OUTPUT OF THE BURNER
The burners have been certified in combustion
d=0,8
chambers according to EN 676 standards. Consult

the burner manufacturer if the combustion cham-
ber of the boiler in which the burner is to be instal-
led has smaller dimensions.
