COMBINED GAS VALVE (monobloc) DUNGS (GASMULTIBLOC)
mod. MD-ZRDLE 415 B01 S22 (1"1/2) / MB-ZRDLE 420 B01 S22 (2")
The monobloc DUNGS model
MB-ZRDLE B1..S... consists of:
a) Min. gas pressure pressure
switch (10) adjustable from 5 to
120 mbar.
b) Gas filter (8).
c) Pressure regulator (stabiliser)
(7).
d) Safety valve (incorporated in
the pressure regulator), rapid
opening and closing (9).
e) Main valve with two positions
(1st and 2nd flame), slow ope-
ning with adjustable initial rapid
release and rapid closing (6).
Adjustment instructions:
1) Entry filter (8) accessible for
cleaning by removing the closing
plate situated in the lower valve
wall near the filter seat
2) Pressure stabilisation adjustable
from 4 to 32 mbar through the
accessible screw by displacing
the cover (13) laterally. The full
stroke from minimum to maxi-
mum and vice versa requires
ca. eighty full turns, do not force
against the limit switches. Before
starting the burner, turn at least
15 times towards the sign (+).
Around the access hole there
are the arrows with the symbols
showing the direction of rotation
to increase pressure (clockwise
rotation) and to reduce it (anti-
clockwise rotation).
Initial rapid release adjustment
affecting both the first and the se-
cond valve opening position. The
rapid release adjustment and the
hydraulic brake affect the 1st and
2 position of the valve propor-
nd
tionally to delivery adjustments.
To carry out adjustments, loosen the
protection cover (1) and use its rear
part as tool to rotate the pin.
Clockwise rotation
= smaller rapid release
Anticlockwise rotation
= bigger rapid release
The stroke from "completely clo-
sed" to "completely open" is ap-
prox. three turns.
FIRST POSITION ADJUSTMENT
(1 STAGE)
st
Loosen the screw with projecting
cylindrical head (3).
Rotate the second flame delivery
adjustment handle by least one
turn in the direction shown by
the arrow with the sign (+) (anti-
clockwise rotation).
CAUTION:
if said adjusting handle for the 2nd
flame is not rotated by at least one
turn towards (+), the valve does
not open for the first position.
Rotate the adjusting ring (5) of the
1st position in the direction shown
by the arrow with the sign (+) (anti-
clockwise rotation), i.e. a little more
than two turns considering the limit
switch. The regulator clockwise ro-
tation brings about a supply reduc-
tion, while an anticlockwise rotation
brings about a supply increase.

SECOND POSITION ADJUST-
MENT (2 STAGE)
ND
Loosen the screw with projecting
cylindrical head (3).
Rotate the handle (2) in the direction
shown by the arrow with the sign
(+) (anticlockwise rotation) and
adjust the quantity You regard as
necessary to obtain the desired gas
supply for the second flame. The
regulator clockwise rotation brings
about a supply reduction, while an
anticlockwise rotation brings about
a supply increase.
After adjusting the gas supply for
the first and second flame do not
forget to tighten the screw (3) to
avoid undesired displacements.
