The Superior VRT3100 Ventless Firebox has a simple design that is still attractive. This is a universal heat-circulating firebox that comes in three sizes: 32", 36", and 42". All of the sizes are 24" tall and can handle log sets that do not require venting. To customize the look, choose from two high-definition lining options. The Superior VRT3100 Ventless Firebox comes with optional ornamental twin-pane mesh screen doors and a blower to complete the look you've always wanted for your hearth. Note that this firebox does not come with a log set. Individual log sets can be purchased.
