1. Determine the location for the mantel allowing for clear-
ance to walls and furniture according to the fireplace’s
owner’s manual. Place the mantel base against the wall
and mark wall molding on each end of the mantel base.
Move the mantel base, cut and remove the molding so
that the mantel can rest against the wall.
2. Install gas line and check for leaks. Follow the require-
ments of your gas fireplace owner’s manual. Remember
to leave access to the gas shutoff valve where it is ac-
cessible to the user.
3. Align the header and sides so that the trim molding is
flush, see Figure 2. Attach the header to the right and left
sides using two (2) header blocks and six (6) #10 1

ASSEMBLING MANTEL
IMPORTANT: More than one person is required
to lift assembled mantel. Lift mantel by leg
assemblies. Lifting by header or mantel top
could damage mantel.
Use the table below to verify the opening and depth dimen-
sions for each mantel. In addition to meeting these dimen-
sional requirements, clearances to combustibles must also
be maintained according to the fireplace and gas log owner’s
manuals.
