-
MENTS CONCERNING THE INSTALLATION OF FAC-
TORY BUILT FIREPLACES.
Select the location for the fireplace by taking into con
-
sideration the factors previously outlined in the Locating
the Fireplace section of the manual.
Step 1: Framing the Firebox
The width of the framed opening must be 39” for 36”
models or 45¹⁄₄" for 42" models. (Fig. 4)
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: Refer to Pre-wiring the Junction Box and Electri-
cal Service on Page 7.
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.
