della caldaia scaricando acqua dal generatore di calore o dalla batteria di condensazione. La valvola VAST si utilizza anche per
impedire il ritorno di amma nel serbatoio del combustibile immettendo acqua in caso di temperatura eccessiva.

sistema per assicurare che non vi siano impurità che possono depositarsi sulle parti della valvola, causandone il cattivo funzionamento.
Ricordare di installare un ltro a monte della valvola. Il sensore può essere montato in qualsiasi posizione. Assicurarsi che tutto il
sensore sia in contatto con l’area tenuta sotto controllo. La freccia sul corpo della valvola indica la direzione del usso. Installando
la valvola, assicurarsi che questa sia posizionata in modo corretto. Massima coppia di serraggio per il pozzeto del sensore 30 Nm.

prova funzionale viene effettuata manualmente premendo il pulsante rosso che apre il usso della valvola. Il dado di serraggio del
pulsante rosso non deve essere allentato/manomesso per non causare il malfunzionamento della valvola.

APPLICATION The Thermostatic Valve VAST is designed for protection of biomass boilers and re stoves It prevents overheating of the boiler
by discharging water from heat generator or condensing coil. The valve is used also to prevent back-burning in the fuel store by ooding the
fuel in case of excessive temperature.
INSTALLATION of VAST valve on boiler with safety heat exchanger. Before installation of the valve ush the system to make sure that there are
no impurities which might deposit on the valve seat and cause malfunction. Remember to install a lter ahead of the valve. The sensor can be
mounted in any position. Make sure the whole sensor is in contact with the controlled area. The arrow on the valve body shows direction of
ow. When installing the valve, make sure it is positioned properly. Max torque for sensor pocket mounting is 30Nm.
SERVICE It is recommended to check proper function of the valve once a year by qualied personnel. Functional check is carried out manually
by depressing the red button that opens the ow on the valve. The nut fastening the red button must not be loosened as it will cause product
malfunction.
