Fireplace Mantel: Beautiful Extra Filler Piece Installation

When your firebox is raised from the floor you will require an EXTRA Filler Panel piece to fill the gap between your floor and the bottom of the firebox.

NOTE: The Extra Fireplace Mantel filler panel piece is meant to be used at the bottom of your firebox.

Historic Mantels Parts

Cut the filler panels to the required size.  We recommend using an small angle grinder with concrete blade.  Apply construction adhesive to the back of the filler panels. Place the mantel legs to determine the correct measurements.  Do not screw the legs into the wall until the filler panels have been installed.

Determine and mark the position of the legs. Mark sure the legs are level and identical distance on either side of the firebox opening. Use shims to level the mantel legs if required.  Apply construction adhesive to the back of the legs and screw the legs to the wall using the metal wall ties attached to the top of the legs .

Fireplace mantel shelves are cast with a cavity in the back to accommodate wood blocking for support. Locate the wood blocking position by off setting the material thickness at the top of the shelf from a pencil line indicating the top edge of the mantel shelf when set on the mantel legs. Screw wood blocking with wood screws into the wall studs for greatest support. Apply adhesive to the back surfaces of the mantel shelf, top of leg and the top of the wood blocking to ensure continuous contact with the wall. Use bracing to secure the mantel shelf tight to the wall until the adhesive sets.
