Assembly and Installation Instructions
IMPORTANT:
If you are painting an unfinished mantel, apply an oil base undercoat to the mantel before painting. This will seal the
wood. After undercoat dries completely, lightly sand and apply an oil base top coat. If you do not apply an oil base undercoat and
topcoat, the wood grain will bleed through the paint.

Assembling Mantel
1. If you must install mantel flush with wall, baseboard will
prevent proper installation of mantel. Either alter baseboard
to fit mantel or remove baseboard.
2. Insert male twistlock fasteners (located on right side) in
female twistlock fasteners (located on right front) (see Figure
2). Tighten screws of twistlock fasteners one-half turn with
flat head screwdriver. Repeat for left side. This will lock the
fasteners together.
3. Rest header on face boards of right and left sides (see Figure
3). Push sides together to eliminate gaps with header. Push
down on header to ensure a tight fit (see Figure 4). Attach
header to right side with two 1 1/4" screws. Repeat for other
side (see Figure 4).
4. Place one mounting block on back of one of the side face
boards and the front panel. Attach mounting block to front
panel and to side face board with two 1 1/4" screws (see
Figure 4). Repeat for other side.
5. Place top on assembly (see Figure 5).
Make sure molding on top fits properly over front and side
panels. Back edge of top should be flush with back edge of
sides. From backside of mantel, locate predrilled holes near
top of left side. Attach with three 1 1/4" wood screws (see
Figure 6). Repeat above steps to attach top to right side.
Locate predrilled hole near the center of the header. Attach
the header to the top using one 1 1/4" wood screw.
Note:
If using optional hearth base with mantel, move hearth
base to installation location. If using mantel without optional
hearth base, move mantel to installation location.
