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.
