Hey guys,I just installed a englander 30 in my double wide, I have 6 ft of stove pipe and then 6 ft of chimney pipe (double walled).All of the chimney pipe is going out the roof being its a cathedral ceiling..when i was cutting the hole in the floor for the external air pipe ,i notice that the air was really coming through like a breeze. not sure if that matters or not.just wondering with such a short chimney will i have enough draft..
