WARNING
Fire Risk.
• Prevent contact with sagging, loose
insulation.
• Do NOT install against vapor barriers or
exposed insulation.
Placing Metal Hearth Strip
The metal hearth strip (approximately 46 inches x 2
inches) is used to provide added protection where appli-
ance and outer structure meet. See Figure 5.1.
• The metal hearth strip flashing may be bent or trimmed
to fit rough opening width. Reference dimension "D" in
Figure 3.3.
• Place a generous bead of silicone caulk on the under-
side of the hearth strip, between the hearth strip and the
appliance, and into the corners of the hearth strip and
framing.
• Place the metal strip onto the structure where the outer
edge of the appliance will sit. It should overlap building
paper to prevent water infiltration.
• Ensure the weep-hole slots in the outer floor of the appli-
ance are clear of any caulk, finishing materials or other
debris.
APPLY HIGH TEMPERATURE SEALANT
(300 °F/149 °C min.)
