This unit is not designed to operate with the doors open without overfiring the unit. It does not allow for a gas or propane line to be run into the firebox.

Warm & Efficient: Superior WCT6940 Firebox!

This fireplace insert provides amazing heat, and is surprisingly easy to maintain. Installation was a bit involved, but the performance makes it worthwhile. I'm very happy with the efficiency.
