A vent-free heater takes its air from the room. The room must have at least 50 cu. ft. of volume for every 1,000 BTU/hr of all appliances in it, or extra ventilation must be provided as the manual describes. Input ratings are for elevations up to 2,000 ft.; reduce 4 percent for each 1,000 ft. above that.
Vent-free gas appliances are not allowed in every state, city or room. Check your state and local codes before you order. Installation and service must be done by a qualified installer.
