INSTALLATION
The SIT 822 NOVA control valve 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 requirements relating to the number and class of the
automatic solenoid gas flow on-off valves and to the class of 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.
