Hi all! We currently have a Drolet Savannah and are in the process of planning some renovations thus summer. We would like to somehow construct a firebox where we can insert a fireplace insert to connect up with our existing triple wall chimney where the Drolet vents. We do not have a fireplace currently, so we would need to essentially cut a hole in the wall, construct a box where the insert could sit and vent it straight up into our existing chimney. I'm curious if anyone has done anything similar, and I also want to make sure we can construct the box to meet any requirements to install the insert. The insert will obviously need to be insulated itself or have some other form of construction where it is safe. Does anyone have any experience or knowledge of doing such a thing? Thanks!
