Sorry for starting another post, but I wanted to ask some more general questions. I have spent most of the day researching wood inserts for my ZC fireplace and stopped by a couple of dealers. I realize the best approach is to just rip it out, but I prefer to not do that with a 32' chimney. My measurements are: Front width: 36" Rear width: 24" Height: 20" or 21.5 if I cut the lip off in the front Depth: 17.25" I see a lot of stoves have a min height of 21.5. Is it OK to just barely meet the min? What about installation? From the picture you can see my fireplace is raised off the floor. The medium size inserts often stick out the front. Do these require a hearth that is flush to the floor or the inner box? Can I have the front stick out without the support. I know a Jotul C350, Hampton HI200, and a PE Vista will go right in. I looked at the C350 today and the firebox is so small. I am not looking for really long burns, but is such small firebox able to accept standard logs? I like the looks of the Jotul quite a bit. Thanks for your advice.
