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 coun-
ter-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".
