pb said enough to deter you from doing the job yourself. It may be worth a hundered dollars or 2 to have an installer come to the house and see what he'd charge to ADVISE you on this job, and even inspect it and even be available for phone advice. Do understand that if you get into this type of agreement, you won't be his priority because he's out making a living doing installations. And, if you have any problems with the install, he may not be readily available. Be prepared to talk to him about this.
The stove needs to be on a surface that's a certain dimension 'bigger' than the stove and on a surface that's not flamable. Also, there's piping considerations. In other words, going through the wall to the outside is fine but can it be near your heater chimney vent (if you have one), or a gas line (if you have one), etc., etc.. With all due respect, unless you can get someone who knows what their doing in an advisory capacity, save $1000 and have a pro do it next year. You can maybe have a pro install the 'opening' to the outside of the house (and temporarily seal it for the winter) so you can go ahead and do your siding. Then, next year, he can come back to finish the job. Just make sure you're SURE of where you want the opening to be.
My best to ya and hope this helps.
PS: Do tell your insurance company when you're finished. In fact, tell them you're looking into this job and would like to know what they'd require so you're covered. (Permits, copy of contract, or whatever ...)
