The monobloc DUNGS Model MB-ZRDLE is made up of:
a) Minimum gas pressure switch (3) and maximum gas pressure (12)
b) Gas filter (6)
c) Pressure regulator (stabilizer) (2) (only for version B01)
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 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 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 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 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.
