It is located at the front of the flow manifold body to which it is coupled. When this valve trips it causes water to come through the system flow pipe to which an extension pipe (4) is connected that ends with a collection funnel (5). System flow STV75 ed 01/08 VICTRIX 75... -
Page 10: Gas Valve
Through nozzle (6), gas is injected at the inlet of the Venturi pipe (5) where pre-mixing begins with the combustion air. The resulting mix is ignited on the cylindrical burner surface (4) by a spark of the ignition electrodes (10). STV75 ed 01/08 VICTRIX 75... - Page 11 At the end of the Venturi pipe is a pressure pick-up point where the input signal (P1) is read. This signal is conveyed to the pneumatic valve regulating the gas pressure via a silicone pipe. STV75 ed 01/08 VICTRIX 75...
