Note: When elevating the fireplace above the hearth

protected with a protective metal hearth strip (not included)
as shown in Figure 18.2.
• Place the Protective Metal Hearth Strips
Included with your fireplace you will find two metal
hearth strips measuring approximately 23 in. x 4 in.
(584 mm x 102 mm). These strips are used to provide
added protection where the fireplace and the hearth ex-
tension meet.
Slide each metal strip 2 in. (51 mm) under the front edge
of the fireplace. The individual pieces must overlap each
other by 1 in. (25 mm) minimum in the middle of the fire-
place to provide continuous coverage of the floor. See
Figure 18.1. These metal strips should extend from the
front and sides of the fireplace opening by 2 in. (51 mm).
Screw metal strips in place.
Fire Risk!
• Prevent contact with sagging, loose
insulation.
• Do NOT install against vapor barriers or
exposed insulation.
