ADJUSTMENT GAS GOVERNOR

The gas governor, with built-in filter, must be installed so as to stabilise the outlet gas pressure

and to avoid that eventual impurities reach the gas valve. To increase gas pressure, remove the

cover of governor and turn screw C. Unscrew screw C to reduce pressure, then fit the cover.

Note: the inlet gas pressure must not be higher than the specified max. gas pressure.

CONNECTION TO THE GAS PIPELINE

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.

All burners are factory tested and set at 230 V 50 Hz .

Same recommendations of the oil start. Then put the switch on gas position, give power and close the thermostat con-

sent. The ignition and preventilation phase goes on the same way than oil start. Once the ignition is made regulate the

flow rate by the adjustment of the working valve and set the combustion with the same head and air regulations of the

oil burner start. Inserting a screwdriver on the seat over the valve does the regulation of maximum flow rate: the

clockwise rotation decreases it, the anticlockwise one increases it.

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.
