Any maintenance operation must be performed by qualified personnel.
This device must be installed in accordance with the laws in force.
The GAS REGULATOR SSV is normally installed before the user. It can be installed
in a horizontal position and it must be installed with the arrow on the body towards
the user. (Fig.2).
N.B. Install the GAS REGULATOR SSV away from atmospheric agents.

GAS REGULATOR SSV are single-stage gas regulators with pressure blocking
device.
GAS REGULATOR SSV can be installed in systems with automatic gas burners
and in industrial gas distribution systems.
GAS REGULATOR SSV have three diaphragms fitted inside them: a operating
diaphragm 9, a compensation diaphragm 13 and a safety diaphragm 16
(refer to Fig. 3).
A breather pipe and external discharge is not necessary because the safety
membrane avoids more than 30 dm3 / h, point 3.3.2 of the UNI-EN88-1: 2011
Norms.
The GAS REGULATOR SSV comply with the ATEX Directive 2014/34 / EU as
device of group II, category 2G and as device of group II, category 2D; for this
reason it is suitable for installation in zones 1 and 21 (as well as in zones 2 and
22) as classified in Annex I to Directive 99/92 / EC.
They are NOT suitable for installation in zones 0 and 20 as defined in the Direc-
tive 99/92 / EC.
We recommend checking the CEI EN 60079-10-1 standard to determine the
qualification and extension of hazardous areas.
GAS REGULATOR SSV are equipped with:
• OVER PRESSURE blocking device (SSV) that blocks the pressure flow
when the output pressure of the GAS REGULATOR SSV exceeds the set limit
(OPSO).
• UNDER PRESSURE blocking device that blocks the pressure flow when
the output pressure of the GAS REGULATOR SSV is lower than the set limit
(UPSO).
WARNING: The GAS REGULATOR SSV will remain operated only if the pres-
sure downstream is between the maximum value (OPSO) and the minimum
value (UPSO) set.
Fig.3Fig.2
• Before proceeding with the installation, make sure that the gas supply has been
shut-off.
• Check that the line pressure does NOT EXCEED the maximum pressure stated
on the LABEL OF REGULATOR SSV.
• Make sure to respect the gas flow indicated by the arrow on the body of the
GAS REGULATOR SSV which must always be directed towards the user.
• It is necessary to install an impulse socket for the shut-off valve with G 1/8
“connection and an impulse socket at the output of the GAS REGULATOR SSV
at a distance of 5 times the nominal diameter of the pipe from the output of the
same (Fig.3).
The two impulse sockets must be connected to each other with a copper tube
with G 1/8 “connection.
GAS REGULATOR SSV if installed according all the indications of the following
document it will not constitute a source of danger.
Only in particular fault conditions it will they be able to release flammable sub-
stances into the environment.
If the GAS REGULATOR SSV are installed in critical area (places not protected,
lack of servicing, lacking availability of ventilation) and, especially in presence,
close to the regulator, of potential sources of primer and/or dangerous devices
during the normal working because susceptible to origine electric arcs or sparks,
it is necessary to value before the compatibility between the regulator and these
devices, we recommend removing the protective cap and connecting a tube with
M10X1 connection. Place the other end of the tube outside the room. In this case
the exhaust gas will be expelled into the external environment.
Make sure that debris or scraps have been created inside the network piping.
Carefully check the connections made and check the tightness of the system.

GAS REGULATOR SSV do not require any specific maintenance. Yearly periodi-
cal inspection of regular working
If necessary, before carrying out any operation with the GAS REGULATOR SSV,
make sure that gas supply has been shut off.
Any maintenance operation must be performed by qualified personnel.

PRESSURE SETTING
Unscrew the Seal cap 1to access to the Spring compressor 3(Fig.4).
The outlet pressure is regulated by rotating the Spring compressor (Fig.4).
Using a 10mm Allen key, turn the Spring compressor 3in a clockwise direction
to increase the pressure and in an anticlockwise direction to reduce the pressure.
After making the adjustment, replace the Seal cap 1.

MANUAL RESET
Make sure there is pressure inside the system and proceed as follows:
- Close the tap downstream of the GAS REGULATOR SSV.
- Unscrew and pull down the Reset knob 36 .
For pressures over 2 bar, hold the Reset knob down until the pressure balance is
created inside the system which allows the SSV to be reset (This may also occur
after several seconds). If this is not the case, it means that the outlet pressure of
the GAS REGULATOR SSV is lower than the minimum set pressure (UPSO).
RELEASE BUTTON
To stop the gas flow, firmly press the RELEASE button 30 .
