COMBINED DUNGS GAS VALVE (monobloc) MOD. MB-
ZRDLE ... B01
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 (lst flame and 2nd flame) which
opens slowly with an adjustable initial 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 mano-
euvring it's regulating screw. it can be reached by sliding the
E
cover (2) to one side. The complete run from the minimum to the
maximum position and viceversa is about 60 turns. Do not force
N
against the end-of-the-run position. Before starting up the bur-
G ner, give the screw at least 15 turns towards the + sign. Around
the screw are arrows with symbols which indicate the sense of
L
rotation to increase the pressure (in a clockwise direction) and
the sense of rotation to decrease pressure (in an anti-clockwise
I
direction). The stabilizer hermetically closes from "upstream"
to "downstream" when there is no gas flow. Different springs
S
to obtain different pressure values from those descrive above
are not foreseen. To regulate the pressure stabilizer, connect
H
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 1st and 2nd opening
positions of the valve. Regulation of the rapid release andof the
hydraulic brake modify the 1st and 2nd positions of the valve in
proportion to the output regulated. 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 2nd flame, at least
one turn in the direction of the arrow which indicates the +sign
(anti-clockwise direction).
ATTENTION: If this knob which regulates the 2nd flame is not
given at least one turn towards the + sign, the valve will not open in
the 1st position.
Rotate the regulating ring (9) of the 1st flame in the direction indicated
by the arrow towards the + sign (anti-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 incre-
ases 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 2nd flame. The
complete run of the regulator from the - position to the + 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 increase it. After regulatiny._the gas delivery for the 1st and 2nd
flame, remember to tighten home the screw (1) to avoid the regulator
moving out of the position at which it has been set.
