I'm looking at the vent and unvented installation of gas log and wondered if you can operate the ventilation system free with open registration. The main reason you might be interested to do that is if it is not too terribly cold, but we want the fire of "environment" and wanted to leave some or most of the exhaust heat from the chimney instead of flowing back into the room.

Nothing will happen, just the heat turns off.
