I have nearly complerted the ME Vertical Boiler, but am confused.
BF12 – The Cap Exhaust fitting is fitted to the Smokebox cap with the small pipe bent up into the chimney. Done, and understood, BUT the other end – on the top of the Smokebox Cap seems to have just an open end. …My question is that all there is to it or does the top portion then connect elswhere. I can find no information other than the fitting and bending the tube into the Chimney. There is a hedding in issue 4608 "Installing the Cap Exhaust fitting."
Any advice and information much aprecxiated
