New member here. Had a question about installing a zero clearance insert. I've been thinking of one for awhile. Currently we have a ventless gas log, and I've thought about removing the gas log and installing a zero clearance insert in its place. The main goal is to reduce heating cost and having a better backup in case of power outage. So how involved is installing a zero clearance insert (generally speaking)? Is this something someone who is mechanically inclined can do pretty easily, or better left to a professional? Doesn't seem terribly involved to me, but I'm sure there are plenty on here who are more experienced at this.
