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 burner will be enabled to run the start-up sequence.

All burners factory tested at 400 V 50 Hz three-phase for motors and 230 V 50 Hz monophase with neutral for auxiliary equip-

ment. If mains supply is 230 V 50 Hz threephase withuot neutral, change position of connectors on burner as in fig. Protect burner

supply line with safety fuses and any other devices required by safety standards obtaining in the country in question.

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 pre-

vents air from entering; - the seal on the flue-boiler pipe fitting; - the condition of the flue (sealed, 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 cham-

ber. 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: 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 suitable 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.
