said by rgod55:The system is a Robert H. Peterson Co Real-Fyre Gas log Set, model apk 10m (or apk 10mp).
From the manual, There is a clamp that is supposed to be on the damper to prevent it from being fully closed, but it should be fully opened when the log set is is "burning". I suspect that the surround may not be sealed correctly.
