INSTALLATION
The 630 EUROSIT complies with current safety standards.
Nevertheless, its installation on appliances must be verified in accordance with the specific
standards for each installation. In particular, it is necessary to ensure that the requirements
relating to the class of flame supervision device and, if present, the pressure regulator
are met. All the installation, setting and adjustment operations must be carried
out exclusively by qualified personnel on the basis of the specific characteristics
of the appliance. The valve must only be installed inside gas appliances
and is not suitable for outdoor use.

MECHANICAL CONNECTIONS

General recommendations
Do not tamper with sealed parts. Do not slacken assembly screws. Do not remove
labels. Avoid blows (knocks, falls etc.). Only remove dust caps when installing.
Do not exceed recommended torques. Ensure that the gas flows in the direction shown
by the arrow on the valve body. Prevent foreign matter from getting into the valve during installation.
In particular, check the cleanliness of the inlet and outlet pipes.
Do not subject the valve to bending in excess of 35 Nm and to torque in excess of 25 Nm.
Use only the specified spanner grips when making the connections.
The valve has 3 pairs of attachment holes.
CAUTION
To allow personalisation of the product in the installation phase, some versions are supplied without some
components. Therefore, check that the valve is supplied complete with:
• minimum gas flow adjustment screw
• maximum gas flow adjustment screw
If not, assemble as follows:
• check that the component code is correct
• insert the minimum adjustment screw into opening
• insert the components and screw in fully.
