The monobloc DUNGS Model MB-ZRDLE is made up of:
a) Minimum gas pressure switch (3)
b) Gas filter (6)
c) Pressure regulator (stabilizer) (2)
d) Safety valve (incorporate in the pressure regulator) which opens and closes rapidly (4)
e) Principle valve with two positions (1
rapid release and rapid closing (8).
Before proceeding with regulation, read the following:
1) It is possible to reach the gas filter (6) in order to clean it, by removing one of the two side closing plates.
2) The pressure stabilizer can be regulated (see table) by manoeuvring it's regulating screw. it can be reached by
sliding the cover (2) to one side. The complete run from the minimum to the maximum position and viceversa
is about 60 turns. Do not force against the end-of-the-run position. Before starting up the burner, give the screw
at least 15 turns towards the + sign. Around the screw are arrows with symbols which indicate the sense of
rotation to increase the pressure (in a clockwise direction) and the sense of rotation to decrease pressure
(in an anti-clockwise direction). The stabilizer hermetically closes from "upstream" to "downstream" when there
is no gas flow. Different springs to obtain different pressure values from those descrive above are not foreseen.
To regulate the pressure stabilizer, connect a water manometer to the rubber tube holder installed on the valve,
to tap Pa (7), in correspondence with the stabilizer exit.
3) It is not necessary to regulate the rapid opening and closing safety valve (4).
4) Principle valve (8).
Regulating the initial rapid release effects the 1

To carry out regulation, unscrew the protection cover (11) and use the back part of it as a tool to turn the pin.
Rotation in a clockwise direction = minor rapid release
Rotation in an anti-clockwise direction = greater rapid release
REGULATING THE FIRST POSITION (1ST FLAME)
Loosen the screw with the protruding cylindrical head (1) Give the knob (10), which regulates the output for the
2 flame, at least one turn in the direction of the arrow which indicates the +sign (anti-clockwise direction).
nd
Rotate the regulating ring (9) of the 1
clockwise direction). As an indication, this should be a little more than two turns from the end-of-the-run position.
Then, when the lst flame only is alight, rotate adequately ring (9) in order to obtain the gas delivery desired.
The complete run of the output regulator, from the - position to the + position, and viceversa, is about three and
a half turns. Rotation of the regulator in a clockwise direction, determines
a reduction in delivery; rotation in an anticlockwise direction increases delivery.
REGULATING THE SECOND POSITION (2ND FLAME)
Loosen the screw with the protruding cylindrical head (1). Rotate the knob (10)
in the direction indicated by the arrow for the + sign (anti-clockwise direction)
as much as considered necessary in order to obtain the gas delivery required
for the 2 flame. The complete run of the regulator from the - position to the +
nd
position, and viceversa, is about FIVE turns. Rotate in a clockwise direction to
determine a reduction in delivery and in an anti-clockwise direction to increa-
se it. After regulatiny._the gas delivery for the 1

which it has been set.
