how can i fix my flu that has been installed wrong, my combi boiler is positioned on a gable end wall and the meter long flu sticks out of the gable end wall, the problem is who ever installed the flu didnt line it up straight it is going up at a 30 degree angle so whenever it rains the water pours right down the flu and into my combi system, it is a vokera linea 7 combi system.

thank you.

Contact your nearest plumbers merchant and explain the problem. They will supply you with a cap that fixes onto the flue pipe to stop rain getting in, but it will allow fumes out...its proper name is a 'terminal'. Frankly, an open flue pipe is plain crazy, and not allowed under installation protocol.
