  • Description

    With flexible installation options, the Exacta firebox can be installed into a pre-existing wood-burning fireplace (converted with a gas line), into a wall or even into a free-standing cabinet. A vent-free firebox is simply the metal combustion chamber needed to house a log set and burner. The Exacta BUF42-R includes a refractory liner for a more traditional fireplace look.

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

    The BUF42-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 front (not louvered) and a large 42" x 24" viewing area. The safety screen can be tucked away into hidden side pockets offering a full, unencumbered view.

    • 41-1/4" Front Width
    • 30-1/4" Rear Width
    • 21-3/4" Front Height
