INSTALL NON-COMBUSTIBLE BOARD KIT
10. Locate the Non-Combustible Board Kit wrapped in cardboard. Open and
discard the largest of the four pieces in kit as this is not applicable to
the install (discarded board measures 50-3/8" x 11-3/4"). The board that
shipped loose within the outdoor see-thru kit will be the top board. Install
the four non-combustible boards as shown in Figure 7 using the supplied
Phillips Head Bugle Drywall Screws. The holes in the non-combustible
boards will line up with pre-cut holes on the facia of the fireplace.
NOTE: Board Measurements:
Fireboard, Top (1/2” x 50-3/8" x 13-3/4")
Fireboard, Bottom (1/2” x 50-3/8" x 9")
Fireboard, Side (1/2” x 40-5/8 x 4-3/8)
INSTALL INNER SHEATHING UP TO NON-COMBUSTIBLE BOARD
11. Install combustible 1/2" thick sheathing (not supplied) down to the
adjoining edges of the non-combustible board (see Figure 7).
INSTALL OUTDOOR SEE-THRU KIT
12. Insert the Inner Glass Mounting Assembly into the fireplace opening
(see Figure 8). There are three slotted holes on each side that will cor-
respond with mounting holes on both sides of the fireplace. Fasten to
the fireplace with six (6) hex head screws.
13. There is a top and bottom to the Outer Glass Mounting Assembly. See
*Note* in detail of Figure 9 for correct orientation. The top overlaps
the sides and the sides overlap the bottom to prevent potential water
infiltration.
14. Install the Outer Glass Mounting Assembly to the Inner Glass Mounting
Assembly with 14 self drilling Bugle Screws around the perimeter. The
circular holes on the outer assembly will correspond to the square holes
on the inner assembly. Ensure the screws drill and bite into the fireplace
behind the non-combustible boards (see Figure 9).

INSTALL GLASS AND BEZEL ASSEMBLY
20. Clean the Inner Tempered piece of glass, front and back (it may be
necessary to use latex gloves to prevent fingerprints). Place the glass
face down on a soft flat surface (cardboard, towel, etc.) on the exterior
side of the fireplace. Firmly place the Glass Removal/Installation suction
tool onto the center of the glass. Clamp the handles together, creating a
strong suction on the glass (ensure strong suction). Carefully place the
glass into the cavity behind the Outer Glass Mount. Lift/angle the glass
upward into the Upper Glass Channel and then place the bottom edge of
the glass into the Lower Glass Channel (see Figures 13 and 14). Release
the suction tool and wipe off any marks left behind during installation.

21. Loosely place two (2) socket head screws into the two bottom center
mounting holes. Clean the Exterior Door glass inside and out. Place the
bottom slots on the Exterior Door Assembly over the socket head screws,
capturing the bottom of the door. Loosely place the rest of the socket
head screws around the perimeter of the door. Once all screws are in
place, tighten the screws, compressing the rubber gasket on the door
(see Figure 15).
22. Place the magnetic Bezel Assembly onto the Exterior Door Assembly,
centering top/bottom, left and right.
CARE AND MAINTENANCE:
It may be necessary to clean the glass and the exterior parts of the See-Thru
assembly periodically. Remove the Bezel, Exterior Door and Inner Tempered
Glass in reverse order of how it was installed shown above. Use a cloth and
window cleaner to clean the glass and exterior facing surfaces. Note: The
glass on the Interior Door Assembly facing the inside of the house must be
cleaned from the inside by removing the Front Door and Barrier Assemblies
(see Installation and Operation Instructions for fireplace).
