I'm getting a woodstove installed in my skoolie and I'm trying to wrap my head around the items needed for properly venting the smoke. I have access to kits like these:
Though I think I'm best off getting the pieces individually to make sure none of it's too long. One store I saw the adjustable flashing (that goes on the roof) and it actually looked HUGE. I'm somewhat concerned that with the sloping/arching roof that this would stick out. In the diagram, is it just ONE piece of insulated pipe from the bottom (at the chimney adapter) to the top (chimney cap), with everything sliding on the outside of it?
Is there much of a difference between having the pipe go thru the roof versus out a window(frame)? If it went out the window frame, I'd assume it's best to remove the entire window and cover the window frame with sheet metal? Or are there other (safe, sturdy, etc) options?
I've seen 6 inch 'insulated' (double/triple wall) pipe, which is I'm assuming the piece that must be going through the ceiling. Something like:
I guess what I'm trying to understand is that this pipe appears to be 6 inch ID, and about 8 inch OD. How does that attach to the 6 inch OD black pipe? Is that what the 'chimney adapter' is for?
Since the roof really is only about 3 inches (I'm guessing) thick, does the insulated pipe have to go through the ceiling? Or does a different piece do that? I only have a 6 inch hole saw and so I'm wondering if a hole that is 8 inches needs to be cut, and if so, how that is usually done?
Also, is there a recommendation for how far a fireproof flooring (brick or stone) should extend in each direction? What material is cheapest? Brick? Paving stone? Tile? Would the tile break? How high should the whole thing be off the floor? 2 inches? 3 1/2?
I saw one recommendation for the walls to be made from fireproof sheetrock (or something), and then maybe a sheet metal wall (corrugated?) with a 1 inch gap to the layer behind it. Is there a recommended # of inches to give the stove space from the side/back walls? My stove is 24x24x24 and so it's pretty big and too much space behind would have it stick out into the aisle. I could honestly only really afford an extra inch or two of space between the stove and the walls.
I was thinking of just getting paving brick or something for the flooring. Would firebrick be a dumb idea (ie retaining the heat being a hazard)? The other option is landscaping pavers. Should something go under the cement layer? Right now I'm keeping the plywood and rubber flooring, so do I add more plywood above the rubber (and also to help make an exterior wood frame, maybe)? Should I mortar the brick? Is metal flooring a bad idea, ie diamond plating? Would that end up being too hot to stand/sit on?
Is there a general guideline for how long the feet need to be (in terms of safety)? I am going to make an angle iron frame and weld the feet onto it and just put the stove box into the angle iron frame. I'm just curious because this adds height to the stove, which affects the stovepipe that I put above the stove.
Most importantly, how far should the fireproof flooring extend beyond the sides that do not have the fireproof walls (I only plan on having two walls, the other two sides will be open)? Should the side with the door have an extra foot or two of flooring? The stove door is about 18 x 18. I plan on having an inlet pipe for fresh air from underneath the vehicle, and so I have to plan how that's attached if there is flooring in the way.
