Jacob, the stuff I've been reading makes me think you are wanting to get into contention for a "Darwin Award" - it may be from your lack of knowledge, but there are reasons why every poster in this thread has been advising you against installing this stove... You should NOT install that stove this weekend, instead you should spend it reading some of the past threads on this board, and some of the various "how-to" articles to get a better feel for what you should be doing. Currently it seems like every post you make gives me another reason to cringe at the bad / dangerous ideas you have - I'd address them, but you have so many it's not practical to list them all...
To start with, mobile homes are built very differently from standard homes, in many ways much lighter, and in ways that make them easier to set on fire. For this reason, a stove that may be reasonably safe in a conventional construction house would NOT be safe in a mobile home. For this reason, current codes REQUIRE that any stove being installed in a mobile home have a specific listing giving a certification that the stove can be safely installed in a mobile home, and listing any additional requirements for making that installation.
Another aspect is that mobile homes are usually built "tighter" than conventional homes, with less air infiltration - this means that the stove must be DESIGNED to be equipped with an "Outside Air Kit" or "OAK" and installed using it. These kits are stove specific, not something you can retrofit.
Because mobile homes are lower, there are special requirements on the way the stack is constructed in order to ensure that you have proper draft - one of the requirements for a mobile home listing is that the stove needs to work with a shorter than average chimney.
Weight is part of it, also the way the heat is put out, the direction the heat is sent in, the clearance requirements, and so on.
On the plus side, there are benefits to getting a newer mobile home approved stove...
1. Modern stoves are MUCH more efficient, because of their less polluting design they get more heat out of the wood by burning the smoke you normally send up the chimney. A modern stove will typically burn about 1/3 less wood for the same amount of heat.
2. Because they are sending less smoke up the chimney, they build up less creosote in the chimney, which means you don't need to clean them as often, and have a lower risk of chimney fires.
3. Modern stoves tend to have bigger windows in their doors, and airwash systems to keep them clean, so you not only get heat, but you get to watch the fire as well.
4. Typically stoves that are approved for mobile homes come with (or offer as options) shields and other design features to GREATLY reduce your required clearances, especially if you do PROPERLY designed and built wall protection systems - this can really help get the stove out of the middle of your room.
5. IIRC, the Fisher stoves put out a huge amount of heat when they were burning - and went through wood in a hurry doing it. I suspect that this would be to big of a stove for your mobile home eve if it were approved. Most mobile home approved stoves are somewhat smaller, and have more appropriate heat outputs.
You may be able to find a modern stove in a good used deal, but even if not, they aren't that horribly expensive - I believe the smaller Englander models, which are high quality stoves at a very good price, are under a grand for the mobile home approved models.
Please learn before you burn - so you don't burn UP!
