I wouldn't run one without a filter. It will **** in all sorts of dust and debris onto the heat exchanger. Also, when that thing fires up for the first time in the winter you could even start a fire if you did wood work in the shop.

Considering the filter is the barrier between the heat source and flammable material in your garage I might be a worrisome. I would follow the manufacturers recommendations for insurance reasons.
You should have posted this in the Heating/AC section, you'd probably get more/better answers in there. Maybe a Mod can move it for you.
I believe you do need an air plenum on the return and most definetly need a filter. Now if it was the dead of winter in your house and it was the sole source of heat, I'd make an exception for the night while it got hooked up.
Not much things worse than losing your furnace in the dead of winter.

Could I just leave it open with no plenum or filter?
Only if you want to **** every bit of dust and lint into it. Also, if you paint in your garage, you'll be sucking those fumes in as well.

The filter ain't gonna keep you from sucking fumes in. Still I'd be more worried having the flame exposed to your garage fumes. That's why mine is in the garage attic - heat exchanger separates the combustion flame from the garage fumes. Seems like a logical way to install one IF you have a separated attic space.
