3CE P MULTI+ INTERNAL
The 3CE P Multi +system (internal version) is a specially designed concentric common shared system chimney for flue gas evacuation and air supply for domestic room-sealed C42, C43, C42P & C43P boilers in flats & apartments, ideally suited for new build projects. This innovative system allows the connection of 2 up to 20 boilers.
In renovation projects, it is an ideal solution in cases where multiple room-sealed condensing boilers cannot be installed on the face of the building and there is a usable service shaft or existing U-duct.
This system requires the use of the Poujoulat flue gas non-return valve unless the boiler is provided with its own non-return valve.
