I have been on Cape Cod the past few days. Believe it or not in a very remote location on a lake. I was remodeling a cottage with a list from the owner to go threw. After work relaxing and fishing. so remote no internet access. I have been reviewing the past two pages of post and cannot answer all . One of the most talked about issues is installing a wood stove or insert in a metal prefab fireplace. Reading most answers or responses I concur, that unless the insert is listed for prefab installation, then it can not be done. Another point not presented is the prefab venting system. It’s not just the cross-sectional code issue but a more troubling one. Many Prefab fireplaces can be designed for up to 1700 degrees venting. A wood stove requires 1800 or higher usually 2100 degrees. One can not vent a wood stove into a pre- fab without addressing bringing it up to code requirements for wood stove usage. I also noticed where a few posters wanted code input. I can’t remember the original post so please pm me and I will try me best to respond. I also saw that BB was planning to replace his older insert. To keep peace on the forum, he best consider a PE stove. I finally got away fished and relaxed after work. What a peaceful setting over looking the lake. Not too far from Otis air force base. Lot of f-16 doing training runs, lot of activity there. . A bit windy last night, so I took the sunfish out for an hour or so. I forgot how much fun sailing on of them was. When I left there was a divorce issue concerning a stove purchase. Has it been solved or are the lawyers drafting up papers?
