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”.
