Can anyone give me input on installing an VC Intrepid in my fireplace? The smaller size means it would fit in all the way, but I wondered if having the back and sides enclosed would mean I'm losing a lot of potential heat? I understand certain fireplace inserts are designed to have the primary heat flow from the front but didn't know how this principle applies to woodstoves. The Intrepid I'm looking at does has a catalytic converter. I'm not terribly fond of fireplace inserts and would like to make this work with a woodstove if possible. Thanks in advance!
