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

VPS504 Gas proving system
The VPS504 check the operation of the seal of the gas shut
off valves. This check is carried out as soon as the boiler
thermostat gives a start signal to the burner, creating, by
means of the diaphragm pump inside it, a pressure in the
test space of 20 mbar higher than the supply pressure.
When wishing to monitor the test, install a pressure gauge
ranged to that of the pressure supply point PA.
If the test cycle is satisfactory, after a few seconds the con-
sent light LC (yellow) comes on. In the opposite case the
lockout light LB (red) comes on.
To restart it is necessary to reset the appliance by pressing
the illuminated pushbutton LB.
