Exhaust Gas Blowing System

The exhaust gas blow system used exhaust gas from the main engines to assist with blowing the tanks to raise the U-boat. A pipe extending forward from the main engine exhaust valves, to led forward to a manifold located over the control room. From the manifold, smaller pipes runs to 8 tanks around the u-boat. The eight associated valves in the manifold were operable from within the control room.
