Just light a little fire and see how you like it. Someone did this before you got there, and someone will do this after you left. Block heats slowly, and doesn't expand much. It is easily as impervious to heat as backer board.
It isn't like you are pouring cold tomato sauce into a pre heated Corning Ware casserole dish.
Store your gas can somewhere else, and pop open the garage door for a minute if you need to vent. Gas vapors tend to pool at the floor, and will flow right out the door.
