In its design gas fireplace heaters have the same type of device found in boilers to operate through gas. Depending on the model, it must be connect to the chimney. Or have a sealed suction cup that eliminates smoke and an exit in the roof. Closed gas fireplaces can be place anywhere and then, offer great installation flexibility. They have a tight combustion and do not draw air from the room . A concentric nozzle system called a suction cup allows the chimney to draw air by combustion from the outer nozzle. And reject the combustion gases through an internal nozzle.
