I'm in the process of building an evaporator. Does the pan sit only above the flat portion of the fire box or over the slanted area as well that goes out to the chimney? I have been in the masonry biz. for 28 years, so I decided to go that route. I have built numerous fire places so I don't worry about some of the problems with home built. Once the design is done I have requests for more.
Thank You
