The reason I am asking is because I had taken the inspector course and this was one of the topics. I also would like to see the forms for the inspector to fill out when they do this. I have asked round and I am not reciving a clear answer. I know that there are people who have taken the course and I know that you would recive a little more info. NACH also has information on the suject of wood burning stoves. THE BIG QUESTION IS DO WE NEED A WETT CERTIFICATE in Ontario.
