Abstract

Scaldacqua a gas con un bruciatore (1), uno scambiatore di calore (2), una protezione fluidodinamica (3), presentante un organo di ammissione (9) del gas di scarico, un organo di ammissione (11) dell'aria ambiente e un organo di scarico (10) del gas di scarico-aria ambiente, e con più sensori del gas di scarico, di cui uno (14) è disposto in corrispondenza dell'organo di ammissione (11) dell'aria ambiente, i quali sensori del gas di scarico indipendentemente fra di loro, al superamento di un valore di soglia, attivano un circuito interruttore che fa cessare il funzionamento del bruciatore. Per ottenere in maniera semplice una sicura disinserzione del bruciatore (1), in casi di accumulo di gas di scarico e riflusso, è previsto che almeno uno degli ulteriori sensori (15a, 15b) del gas di scarico è disposto in corrispondenza di un'apertura (13a, 13b) della cassa della protezione fluidodinamica (3),Gas water heater with a burner (1), a heat exchanger (2), a fluid dynamic protection (3), having an admission organ (9) of the exhaust gas, an admission organ (11) of the ambient air and a discharge organ (10) of the exhaust gas-ambient air, and with several sensors of the exhaust gas, of which one (14) is arranged in correspondence with the admission organ (11) of the ambient air, which sensors of the exhaust gases independently of each other, upon exceeding a threshold value, they activate a circuit breaker which causes the burner to cease functioning. To obtain a safe disconnection of the burner (1) in a simple way, in the event of accumulation of exhaust gas and reflux, it is provided that at least one of the additional sensors (15a, 15b) of the exhaust gas is arranged in correspondence with an opening (13a, 13b) of the fluid dynamic protection case (3),
