Thanks for the links. This is a new subject for me. They were a good read.

This is the first house I have worked on that doesn't have forced air heating. The primary source of heating is in floor heating from a boiler.

I will be honest most of my wood fireplace experience is in camp tents. In those places back drafting is not a major concern. In a house this is a different story.
Yes, a professional has been contacted. That is my friends department. Because Sips are rare in this part of the country he may or may not have experience with them. That is why I'm asking here.
There is venting to replace air but I don't know what kind of unit it is. This house also has a boiler and in floor heat as its main heat source.
Would I be correct in assuming that if we kept the inside air pressure greater than the outside air pressure that there would be no back draft from the fireplace and the largest source of carbon monoxide would be reduced?

Thanks,

Leslie Ball
