Our Answer:

The size feature on the search menu for these inserts is based on width. For our best recommendation for a gas insert, please reply with your preference between direct vent and vent-free, as well as your full fireplace dimensions (front width, rear width, depth, opening height). Also, please advise if your existing fireplace is a brick/masonry unit or a manufactured (metal) unit. For more information, please see our Fireplace Insert Buying Guide.
