Heater placment in a garage

[joseywales]

We are placing a 33k BTU wall/floor heater on our garage. Just trying to decide where to place it.

Standard 2 car garage.

7.5 foot ceilings

Heater won't be left unattended for more than few minutes and only activated by me.

CO detectors in garage, basement, 1st and 2nd floor

It has a cheesy built-in fan, but I have small fans to move the air

Opposite my workspace are floor to ceiling shelves, filled with supplies, so air will basically be trapped on my side of the garage.

A - hang it right next to the basement door, so it directs air down my workspace, toward the garage door. That wall is lined with workbenches. This option would be less intrusive than Option B

B - hang it about 10" from the floor, right in the middle of my workspace. It would be just below a Lower drill center, with batteries, chargers, etc.

C- hang it on the same wall as the benches, but at the end, just in front of the garage door. It blocks cold air from coming in? Upside is that it's less intrusive than B, but not sure it will keep my feet cozy and it's the longest run of the gas line.

Thoughts?

Assume this a ventless gas unit ?

Any flame heater likely needs to be off the floor by more than 10”.

Yes, it is ventless. But it came with feet. We had it on feet for a few years in our basement. Are you saying it can't be on the floor in a garage, or any room?

I'm thinking code in a garage is 8' off the floor for any flame heater because of the possibility of fuel fumes and leaks from cars. Personally I think ventless is a poor choice, you'll get extreme condensation on cars, engines, etc. when it's running. BTDTGTTS.

There is flame distance off the floor in garage install......something like this:

Appliances in residential garages and in adjacent spaces that open to the garage and are not part of the living space of a dwelling unit shall be installed so that all burners and burner ignition devices are located not less than 18 in. (460mm) above the floor unless listed as Flammable Vapor Ignition Resistan

Thanks. Well, my code of common sense served me well then. I would normally have taken at least a day to plan out where this heater would go. But it was a spontaneous decision to install it, or get rid of it, so I shot from the hip. I placed it between the work benches and used a height of "not too high or close to the drill center above it" and "not so low that I can't push a floor jack or something else under it in the summer". So the flams is 22" off the floor

With regard to moisture, etc. I planned on relocating my dehumidifier anyway. Most of the tools are fine, but some of the older, rubber handled, tools get white spots from moisture, so that unit will be turned on year round.

I installed a CO detector and the unit will be used sparingly. I don't expect to spend more than an hour or so at a time in there, at least until the kids are out, and I only use the unit to knock the chill out.

Thanks to everyone who responded.
