Hi all!, I just came in from outside with my kids and wife from attempting to roast marshmallows in a burn barrel fire...WRONG. It got so hot that they couldn't get their hands, holding the stick, close enough, so it got me concerned. The fire was actually full of little pieces from me using a chop saw to cut recently split 20" oak to 17 3/4" pieces, as I plan on updating a heatilator fp to an englander, as stated in title. So, as I don't want to burn my house down, I figured I'd consult some of you more experienced members. I'm an engineer, and I grew up building homes, so, my fear is in my own ignorance of the subject matter. We don't install a whole lot of stoves hear in coastal SC. We currently live in a 2015 singlewide, as we plan on building later, but we've made a decision to purchase more land while our area is still rural, and postpone building for a few years until that's paid off. So, along with that decision, we decided to put a wood stove because honestly, the fp might look nice, but the heat it throws off is a joke, and it can't be upgraded with a blower (per heatilator customer service). The Plan: When it finally warms up a bit, I'll take the hearth, wall panels etc. off, remove the heatilator and chimney pipe up to the ceiling, stuff some insulation up in in and duct tape it s hut. As there is already a hole cut in the ceiling, I'm going to do my best to use that hole, take a plumb bob down the the ground to check my side clearances to see if I can go straight up or if I need to 45 it to gain my clearances. I forgot to mention the fp is in a room corner. If I am able to go straight, I plan on using 1 sheet of the soundproof mineral board (300 something...), in two layers 48" x 48" centered and surrounding the hearth clearances, (I believe it is 8" to the sides, and 16 to the front). On top of that, I'll put a layer of durock and tile. I'd use the 5 layers of durock if it wasn't a MH, need to minimize the weight as best as possible. I'm a little unsure about the side clearances and do I run single run up to the ceiling box? That is, if there is one. Not going to trust that joe blow did it right the first time. I'm really interested in constructive criticism and comments. Weight reduction is obviously important, we plan selling and moving this MH when we eventually build. I did a ton of research and I think I chose a good stove for a 1276 sft, drafty home. Did I? This won't be the only source of heat, I think it'll be more "heat assist", and emergency heat. I'll stop for now as i'm not familiar with forums and whether I'll get any replies, If I do, Thanks in advance!
