The Vent is fitted to the highest part of the solar circuit in order to remove air from the circuit whilst filling.
It is connected in series with a 3/8” isolating ball valve that is closed off after commissioning is complete.
The brass 3/8”— 3/4 “ adaptor contains an integral SS wire mesh filter to protect the precision components.
The flat faced 3/4 “ M BSPP equal T is suitable for connection to DN16 stainless steel Solar Pipe, as shown.
(Solar pipework not included.)
The assembly is rated to withstand the high temperatures of a solar circuit, the Vent to 150 C and the Ball Valve to 180 C.
It can be fitted either inside the roof space or outside, directly to the Collector Outlet.
