garage furnace

I would like to install a natural gas furnace in the 3rd stall of my garage. I live in minnesota where it gets pretty cold. The 3rd stall is walled off from the other 2 stalls, my walls are 12' tall and are insulated and rocked as is the ceiling. I have a Rheem 100,000 btu down flow furnace I would like to use if possible. My question is would I have short cycling problems since the furnace is oversized for such a small area?(400sq ft) Also, could I just hang it up in the corner and let the air blow directly out the bottom without running any ductwork or returns? I realize it would have to be vented outside, but other than that would I have to do anything else? Also what are the pros and cons of a vented vs. a ventless wall mounted heater? This would be another option, but I would like to use the rheem since I already have one. Thank you for your time.

Wow! 100,000 BTU will certainly warm up 400 sq. ft.!!!

Actually I'd be curious to know this as well. I eventually want to insulate my garage and I'd probably either go with electric heaters, or a small furnace.

My main worry would be it may be bad to heat up from around -30C to +20C too fast, unless you keep it running all the time but that's kinda a waste of energy. Garage doors are a huge heat loss.

It will short cycle too much. may not ever warm up the heat exchanger enough. And can cause condensate in the primary heat exchanger, where it doesn't belong.

All points of combustion must be a min of 18" above the floor.
