mOD. mVD ... anD mVDLe ...
The gas valve mod. MVD features a quick opening and closure.
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".
mod. mVDLe OPeraTiOn
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.
nOTe: N.B.There will not be sufficient supply for ignition if the flow
feed device "E" is set at its minimum position. Therefore the
max. flow rate regulator "E" must be opened sufficiently.
regulation of the initial rapid release
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 it clockwise decreases the quantity of gas and turning it
anticlockwise increases the quantity of gas.
This done, return cap "F" to its original position.
maximum output regulation
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".
