WMH Vent-free Sassafras Gas Log & Burner set

The vent-free Slope Glaze burners and matching log sets contain ceramic beads that tumble with the gas to create exceptionally realistic flame movement. Approved for use in any vent-free firebox, it may also be installed in an existing wood-burning fireplace, with the damper closed, to operate as a vent-free heating system. When installed in a fireplace with a damper, you can close the damper to lose none of the heat or open the damper to have the visual pleasure of a fire without the heat.  To know what size is best for you, measure the width of the back wall of your fireplace, and that will give you an idea of which size would fit best.
