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)

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.

Setting scale is „Not" linear! Various sensors available.
Output pressure according to sensor's measuring
range.
Adjust the outlet pressure to the value specified by the
burner or equipment manufacturer!
While making outlet pressure adjustments, do not
exceed a value that creates a hazardous condition to the
burner!
