Chapter 3 - Maintenance
3.1 - General notes
All installation, connection and adjustment operations must be performed only by qualified personnel and
according to the specific properties of the device. During installation it is important to verify that the gas flow is in
accordance with the arrow on the valve body.
The valves are designed in order to be able to operate inside the cooking appliances, protected by any possible
liquids or dirty infiltrations and by the atmospheric agents. The non-compliance of such a prescription may
prevent the right functioning and the safety of the product.
It is absolutely forbidden to tamper with the sealed parts, unscrew the assembling screws and remove any part or
marking on the valve. It’s good to avoid that the valve suffers any kind of shocks (bumps, falls etc.)
In order to avoid any foreign body to enter into the valve, which could compromise the right functioning of the
valve, it is necessary to assemble a proper filter; the inlet filter must be provided upstream of the manifold as
required by the standard.
No kind of maintenance on the valve is allowed. It is absolutely forbidden to
Tamper with the sealed parts, unscrew the assembling screws and remove any part or
marking on the valve. The parts of the device mounted or adjusted during
manufacturing and not intended for manipulation by the user or installer must be
adequately protected.
