ADJUSTING AIR AND GAS FLOW RATES
Gas Filter
The gas filters remove the dust particles that are present in the gas, and prevent the elements at risk (e.g.: burner valves, counters and
regulators) from becoming rapidly blocked. The filter is normally installed upstream from all the control and on-off devices.
Adjusting the injector gas flow rate: Brahma EG12*R valve and pressure governor
To change the injector gas valve flow rate, proceed as follows:
1
remove the protection on the bottom of the valve, moving it counterclockwise (see next picture);
2 rotate clockwise the nut 1 as shown, to close the valve; counterclockwise to open the valve.
To perform a finest adjustment, act directly on the pressure governor as follows (see next picture):
3
remove the cap T : to increase theoutlet gas pressure, use a screwdriver on the screw TR as shown in the picture below. Screw to
increase the pressure, unscrew to decrease; once the regulation is performed, replace cap T .
