Help me heat my garage??

I built my wood stove from 10 gauge stainless steel I have fire brick along the bottom and I have control of the supplied air from a tube I ran through the back . I haven't installed it in the garage as of late but I'm wanting to before winter. This is in no way small so I don't want to have it too far from my wall so does anyone know a basis on distance I could follow to make it a safe install so I don't burn my garage down? I've included a few pictures to try and help you experts have the required information for an educated answer but they don't show how big it is. The dimensions are 3' deep and a 2' diameter. Thanks ahead of time for anyone who takes the time to answer my question. Also if you have any ideas or concerns about how I could make it better or why it will kill my garage feel free to let me know.

I'm not an expert, and I may be very wrong, but I can't say that experts will be able to help you with the information that you have provided thus far.  I can't make sense of your design, but it may be just me, so don't take it personally.  

Questions that might be helpful so that those more expert than I can help you:

1.) Are you loading wood through the upper hatch, and if so, what is preventing smoke from coming out the hatch when you are reloading an existing fire?  
2.) Where does the gas exhaust when the hatch is closed?  
3.) Have you tested this stove outside?
4.) What design did you base your model on?

Nice looking build.  

That's a beautiful stove!  Canada says you should keep it 4 feet from your wall (Woodheat.org).  

A couple thoughts on it:
When the door heats up, if it warps a bit will it put your locking pin on a bind and keep you from opening the door?
Usually stoves have rope gaskets on the door to seal them up nicely.  Not sure how important it is for your design since it could work differently from commercial stoves.
How does your homeowner's insurance company feel about a homemade stove?  
If the only thing above the fire is one layer of stainless, the top of that sucker will be cherry hot.  Keep the little ones away.

Edit to add - My assumption is that the stove is sitting on its back in the first picture and it will get legs at some point.  The door faces front and the chimney points up at the rear.  If that's wrong, my comments above may not be accurate.

Yes it is sitting on its back, there is the gasket on the door(pics were taken just after weld process), and the legs have been built for a while. The inside pic shows the spark arrester which is open on all sides( just blocks straight travel to the exhaust) and is also 10 gauge stainless. I tried to upload a video of it during its first burn but the site wouldn't let me upload .mov files
