Please read through these installation instructions
and visualize the steps before beginning the installation.
Equipment needed for drywall location : Hammer, nailset, electric drill or
cordless drill, drill bits, wood saw, measuring tape, woodscrews at least 3 1/2"
long (course-thread deck screws work well) or nails at least 3 1/2" long (screws
are preferred), screwdriver for deck screws, molly bolt anchors with long bolts
(or equal), 2" finish nails, level, stud finder (can be very helpful but not
required), “Liquid Nail" construction adhesive or equivalent, and wood putty.
For brick location : Masonry drill bit for heavy duty masonry anchors and
companion bolts or screws that will extend 1 1/2" outside the anchor (for
mounting board) when fully screwed into anchor. Use a minimum of three to mount
mantel shelf mounting board.
General sequence of steps is to momentarily position mantel shelf on
fireplace in order to determine preferred height and width, locate where mounting
board will go, then install mounting board, then install mantel shelf. (If using
leg kit install it first).
Parts list:1 mantel shelf, 2 mantel shelf corners (1 left and 1 right), 1
mounting board (2x4).
(Mounting board for the El Dorado is 1 1/2" x 1 3/4")
Step No. 1 : Place mantel shelf above fireplace momentarily to
determine mantel shelf width and height, top is typically 46" to 52" from floor.
The Uniform Building Code specifies that wooden mantels have a clearance of 12"
from the top and sides of the standard fireplace opening (slightly less in some
cases). However, some local codes vary and some firebox inserts and stoves
require more or less clearance. Please consult your local fire Marshall or
building inspector and the instructions of the insert or stove maker. Conforming
to the code is the responsibility of the homeowner/installer. JIFFY-TRIM MANTEL
cannot be responsible for incorrect installations of mantels. With these
considerations in mind decide on your preferred mantel shelf width. Set mantel
shelf aside.
Step No. 2 : Remove either one of the corners (but only one). With the corner
removed, mark the amount that needs to be cut off. Starting with the top. Now
mark the same amount on the face and bottom (see figure #4). Caution: (when
cutting face and bottom do not cut through top). Cut top,then cut face and
bottom. Remove cut piece (pull finishing nails if necessary) and sand smooth the
area where the face was connected to the top.
Step No. 3 : Slide corner back on mantel shelf and place above fireplace at
predetermined height. If mantel height is OK continue on to step No. 4. If height
is not OK make adjustment now, (remember to keep proper clearance from firebox)
then proceed to step No. 4.
Step No. 4 : With mantel shelf in place and level, on your wall, lightly mark
along the top of mantel shelf, also mark center of shelf. Set mantel shelf
aside.(Draw a line parallel to the top of the mantel line 3/4" lower). This line
indicates the top of the mantel shelf mounting board. Cut mantel shelf mounting
board (cut mounting board 6" less than overall mantel shelf length), mark the
center of mounting board.
Step No. 5 : Attach mounting board to wall using both “Liquid Nail" and
drywall screws (make sure centerline mark on mounting board and centerline mark
of mantel shelf are aligned) . Or use masonry anchors if brick or stone surface.
Use the long screws or nails into all studs covered by the mounting board. If no
studs are present behind the drywall, use molly bolts (or equal) spaced every 12"
along the length of the mounting board.
Step No. 6 : Fit mantel shelf over mounting board to desired location. If any
adjustments to mounting board is needed do this now. Pre-drill nail holes 3/4"
from the wall every 8" across the top of the mantel shelf where it overlaps the
mounting board (using a drill bit slightly narrower than the finish nails), then
attach the mantel shelf to the mounting board using both “Liquid Nail" all along
the top of the mounting board and then the finish nails. With a hammer and
nailset, set each nail head. Fill nail holes with wood putty. Allow “Liquid Nail"
to dry (per manufactures directions) before placing weight on mantel shelf.
