exposed insulation.

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 two metal
hearth strips measuring approximately 26 in. x 4 in.
(660 mm x 102 mm). These strips are used to provide
added protection where the fi replace and the hearth ex-
tension 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 4.4. These metal strips should extend
from the front and sides of the fi replace opening by 2 in.
(51 mm).
Note: When elevating the fireplace above the hearth
extension the front of the elevated platform must be
protected with a protective metal hearth strip as shown in
Figure 4.6.
• 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 fireplace opening for square. Measure diagonal
distances of the opening to make sure they are equal.
If they are not, continue to shim the fi replace until those
diagonals are equal.
