or:Ventless gas stoves are prohibited in Canada and some US states. IMO you need your head examined to use one anywhere for any reason. Gas consumes oxygen and produces small amounts of smoke. Not breathing one or breathing the other can cause serious conditions such as death. Anything with a flame needs a fresh air intake vent from outside and an exhaust vent to the outside.
