PART III: OPERATION
Gas valveversion with SKP2 (built-in pressure stabilizer)
To increase or decrease gas pressure, and therefore gas flow rate, remove the cap T and use
a screwdriver to adjust the regulating screw VR. Turn clockwise to increase the flow rate,
counterclockwise to reduce it.
MultiBloc MBE Regulation VD-R whith PS
Decreasing pressure
Fig. 7
ATTENTION: To set the outlet pressure of the VD-R regulator, act on the adjustment ring nut (Fig. 10)
The position of the indicator in the dial indicates the value of the outlet pressure calculated as a percentage of the
full scale of the PS sensor (Fig. 11)

While making outlet pressure adjustments, do not
exceed a value that creates a hazardous condition to the
burner!
