Step 3. Positioning, Leveling, and
Securing the Fireplace
Placing the Protective Metal Hearth Strip
Included with your fireplace you will find a metal flashing
strip measuring approximately 46” x 4”. This strip is used
to provide added protection where the fireplace and outer
structure meet.
• Place a generous bead of silicone caulk into the corner
of the protective hearth strip. Place the metal strip onto
the structure where the outer edge of the fireplace will sit
(see Figure 6).
• Place the fireplace into position. Make sure flashing edges
on the outdoor surround fit up tight to the framing.
The diagram below shows how to properly position, level,
and secure the fireplace. Before the framing or fireplace is
set in place, the cutout should be covered with tar paper or
similar material.
The outdoor side of the fireplace contains edges that protrude
beyond the normal envelope of the fireplace. Special care
should be taken to avoid damage to these parts.

Securing of a Fireplace
Figure 6.
Positioning the Metal Strip
• Level the fireplace from side to side and front to back.
• Shim the fireplace with non-combustible material, such
as sheet metal, as necessary.
• Secure the fireplace to the framing by using nails or screws
through the nailing tabs.
• See Figure 7 for placement of combustible housewrap or
building paper and non-combustible sheathing for the
outside wall. Combustible housewrap or building paper
may be brought over the fireplace flange, but not past
the bend in the flange (see Figure 8).
• Once the fireplace is in place, put protective flashing
corner cover pieces (found in manual bag assembly) over
top corners on outside of unit (see Figure 8). Use sili-
cone caulk to place these pieces over the corners and
secure into place. Make sure enough silicone caulk is
used to make a water tight seal between outdoor sur-
round and corner pieces.
