Come on baby light my fire

We had a opening framed in the shaft that runs through the house that houses all the ducts, piping, and wiring to accomodate the fireplace. After much research we decided on the Napolean Modern 46" gas fireplace. We loved the look of this type of fireplace. We connected the electrical ignition and ductwork and then furred the face of the opening. The surround must be a non-combustable material. We used fire rated gwb covered in cement board that was reclaimed from the front facade.
