INSTRUCTIONS FOR SETTING DUNGS GAS
VALVES MOD. MVD ... AND MVDLE ..
The MVD gas valves open and close rapidly.
To regulate the gas flow, unscrew and remove cap "A" and loosen
nut "B".
Then, using a screwdriver turn screw "C". Unscrewing it increases
the gas flow, tightening it decreases the flow.
After regulating, lock nut "B" in place and reposition cap "A".
HOW THE VALVE FUNCTIONS mod. MVDLE
The gas valve has a rapid initial trip (opening can be adjusted from
0 to 40% using pin "G"). Full opening from that point on takes place
slowly over approximately 10 seconds.
N.B. There will not be sufficient supply for ignition if the flow feed
device "E" is set at its minimum position. Therefore, it is
essential to open the maximum flow rate control device "E"
sufficiently to ensure ignition.
Setting the initial rapid release trip
To set the initial rapid release, unscrew the protection cap "F" and
use the back of this cap as a tool to turn pin "G".
Turning clockwise decreases the gas flow, turning counter-clockwise
increases it.
This done, return cap "F" to its original position.
Setting maximum gas flow
To adjust the gas flow rate, loosen screw "D" and turn knob "E".
Turning clockwise decreases the gas flow, turning counter-clockwise
increases it.
This done, tighten screw "D".
