Hi
Has anyone had experience with a return grill right next to a traditional fireplace. My concern is lighting a fire and having the fan kick on and possibly
pulling smoke or vapors out of the fireplace and into the air system.

The grill is the main return 20x20.
The easy answer is move it, but due to design restrictions thats not so easy. The system is not finnished so it can not be fired up and actually tested yet to see if this will be a problem.
Thanks Tom
