Gonna install wood burning stove and gonna do a 90 right off the top of the stove to a two foot pipe going out the wall to a T then have a 30 degree elbow going up 8 feet. Main question is it ok to have a 90 right off the stove. Is the draft gonna be ok to have fire in my stove?

It's a vogelzang boxwood stove rated to heat 900 sqft. Gonna have it in my garage to heat it up. Set up I have plan is 90 right off the stove to a two pipe out the wall to a T box or whatever it's called then 30 elbow right off it up 8 to 9 feet to be past three feet above my roof.
I forget the formula, but I think it's something along of the lines of needing 3' extra to compensate for any 90 degree elbows factored into your overall chimney height depending on what's recommended for your stove? Mine is only 30" from the stove to the 90, but and then another hard 90 out of the thimble up the chimney, but I put a on some extra height and still managed to hit the sweet spot in draft. I initially had a slight slope up to the thimble after the 90 out of the stove, but it actually created too much draft. Just try to get within the specs of your stove and play with the design until you find best draft.
Ok so 8 or 9 feet minus 3 for the first 90 minus 3 for the second 90 minus one for the 30 means you will only have the equivalent of a 1 or 2 foot chimney. It will not create enough draft at all.
Also you should know in the US it is against code to have a solid fuel burner in a garage. If anything happens chances are insurance would deny the claim.
Coming straight up off the stove and switching to chimney pipe at the ceiling level through the roof would work the best. With that stove 8 to 9' is probably enough. But check the specs
Definitely check out the manual for it. It looks like it requires a 36" vertical section minimum before a 90 can be installed. 11' chimney height overall from top of stove minimum, and some huge clearance requirements from the stove to combustibles (compared to more modern stoves).
Some stoves explicitly say it's okay to install a 90 right off the bat but this does not appear to be one of them. I am not enough of an expert to say if this is a situation where one can skirt this part of the installation instructions.
