Abstract:
A retrofit firebox assembly includes a frame, a floor, and sidewalls. The frame has a plurality of vertically extending spaced apart tube members to which solid masonry units are mounted. The back wall has a metal plenum member with a lower vertical portion, a lower angled portion, a central vertical portion, an upper angled portion, and an upper vertical portion, positioned to form a smooth, symmetrical bulge in the back wall extending into the firebox. The solid masonry units are positioned on their respective frame members using clips that position, align, and support the units. The metal plenum provides spaces for air to flow into the firebox between the lower vertical portion and the lower angled portion; and between the lower angled portion and the central vertical portion.
