I just had a tankless water heater installed. The plumber that installed it got rude with my wife so she threw him out of the house so I can't call him to come back and fix the problem. The unit works fine with the front off. If you put the front on it with in a minute of it firing it shuts off. I believe that it is starving for air. The vent is threw the roof and I believe that it is too long of a pipe and not big enough diameter. Any ideas of how to remedy this problem?
