This fi replace may be placed on either a combustible or
noncombustible continuous fl at surface. Follow the in-
structions for framing in Section 3.D. Slide the fi replace
into position. Be sure to provide the minimum air clear-
ance at the sides and back of the fi replace assembly.
See Section 3.B.
WARNING

• Prevent contact with sagging, loose
insulation.
• Do NOT install against vapor barriers or
exposed insulation.
• Place the Protective Metal Hearth Strips
WARNING
Fire Risk!
• Metal hearth strips MUST be installed.
Sparks or embers may ignite fl ooring.
Included with your fi replace you will fi nd four metal
hearth strips measuring approximately 28 in. x 4 in.
(711 mm x 102 mm). These strips are used to provide
added protection where the fi replace and the hearth ex-
tensions meet.
Slide each metal strip 2 in. (51 mm) under the front
edge of the fi replace. The individual pieces must over-
lap each other by 1 in. (25 mm) minimum in the middle
of the fi replace to provide continuous coverage of the
fl oor. See Figure 4.3. These metal strips should extend
from the front and sides of the fi replace opening by 2 in.
(51 mm).
Note: When elevating the fi replace above the hearth exten-
sion the front of the elevated platform must be protected with
a protective metal hearth strip as shown in Figure 4.4.
• Level the Fireplace
Level the fi replace side-to-side and front-to-back. Shim
with noncombustible material, such as sheet metal, as
necessary. Secure the fi replace (using the nailing fl ang-
es located on either side of the fi replace) to the vertical
framing.
Important: To ensure proper fi t of the glass doors, check
the fi replace openings for square. Measure diagonal dis-
tances of each opening to make sure they are equal. If they
are not, continue to shim the fi replace until those diagonals
are equal.
