If you have a clean blue flame and you are well ventilated, boiling inside your garage is no problem at all. I always use my garage with the side door open and the garage door cracked about 12" off the ground. Think about it people, a gas stove is IN your home and you don't need to run a hood for that. As long as your burn is clean and you provide some ventilation you will be fine. I don't recommend using your burners inside your home but your garage, No Problem At All. FYI, keep your burner away from combustable material. I recommend at least three feet from walls. you don't want to burn down the neighborhood.
