8 chimney cap – If we have a chimney that last year worked perfectly, and this year, when we went to turn it all the smoke went out into the room where we have installed, the most probable cause in these cases is that we have made a Nest the birds and we are plugged the duct. We also found, a case where a plastic bag had been put in the flue and also did not let the smoke out, and another case that we have found is that a customer. Put a wire mesh to prevent them from entering the birds.

This happens, because the smoke, tries to move the air that is on top of it inside the smoke duct
