  • Description

    Installing a firebox offers a homeowner flexible installation options. The Exacta firebox can be installed into a pre-existing wood-burning fireplace that has been converted with a gas line or into your wall. A vent-free firebox is simply the metal combustion chamber needed to house a log set and burner (sold separately). The Exacta BUF36-R includes a refractory liner for a more traditional fireplace look.

    With a vent free firebox, fresh air is drawn in at the bottom of the firebox, and warmed air is expelled into the room from the top. The Exacta firebox features an angled top design to help direct the warm air out for maximum efficiency. A blower (BLOTMC) can be added to help circulate the warm air.

    The BUF36-R firebox can accept most 18", 24" and 30" vent free log sets and a burner is also required (each sold separately). With zero clearance, the firebox can be installed flush against any surface like drywall or wood.

    The Exacta firebox offers a clean louverless face and a large 36" x 24" viewing area. The safety screen can be tucked away into hidden side pockets offering a full, unencumbered view.

    • 35-1/4" Front Width
    • 27-1/4" Rear Width
    • 21-3/4" Front Height
