COMBINED DUNGS GAS VALVE (monobloc) 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)
()
d) Safety valve (incorporate in the
pressure regulator) which opens
and closes rapidly (4)
e) Principle valve with two positions
(lst flame and nd flame) which
opens slowly with an adjustable ini-
tial 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 re-
moving one of the two side closing
plates.
) The pressure stabilizer can be
regulated (see table) by manoe-
uvring it's regulating screw. it can
be reached by sliding the cover
() 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 pres-
sure (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 wa-
ter 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 relea-
se effects the 1st and nd opening
positions of the valve. Regulation of
the rapid release andof the hydraulic
brake modify the 1st and nd posi-
tions 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 direc-
tion = greater rapid release
REGULATING THE FIRST
POSITION (1
Loosen the screw with the protru-
ding 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).
Rotate the regulating ring (9) of
the 1st flame in the direction indi-
cated 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 ade-
quately 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
ND
POSITION (2 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 regula-
tor moving out of the position at
which it has been set.
