Yes, this is a wood burning fireplace. I believe the opening was approximately 50" wide x 32". I have seen much larger openings on full masonry fireplaces. In all cases the flue will need to be installed and sized correctly so that it draws/vents properly. They also make sealed wood burning units with doors and fan kits that provide better room heat, however some would argue the aesthetic charm of the open firebox is lost with those types of units. Thanks for looking and Happy New Year!!

The opening would depend on your building code and insurance company
