The entire fireplace can be elevated above the floor
to achieve a raised hearth effect. This can be done by
adding a small platform to achieve the desired height.
NOTE:
If installing a blower kit on the fireplace, the
lower grille must be even with the floor. The wiring re-
quired for the lower blower must be installed during the
framing stage. See blower kit installation instructions for
wiring requirements. The nailing flanges on both sides
were designed to allow the installation of 1/2” wall-
board or plywood flush with the face of the fireplace.
Step 2: Install the Firebox
Install the firebox into the framed opening by setting
it directly in front of the opening and sliding it into the
proper position.
Step 3: Level the Firebox
Check the level of the firebox on the top edge of the fire-
place face. Shim if necessary.
Step 4: Secure the Firebox
Four (4) nailing flanges are supplied with the fireplace
(found on the fireplace hearth). To level the box and
secure it firmly in place, remove the nailing flanges from
the hearth and install at the sides of the fireplace as
shown in Figure 5.
NOTE:
The nailing flanges have two (2) sets of holes
to allow for adjustment for 1/2” or 5/8” offset of the face
of the unit. When installing the nailing flanges, choose
the set of holes on the nailing flange that fit with your
application.
