Installation of a ceiling restop is required
• Refer to Figures 8.8 - 8.10.
• Roll the shield (around the chimney if already installed)
until you have a 3 in. (76 mm) overlap and the three
holes on each side match up (large holes on top).
• Insert three screws into the matching holes to form a
tube.
• Bend three tabs on the bottom of the tube inward to 90°
to maintain chimney air space (refer to Figure 8.8).
• Rest the insulation shield on the ceiling restop below.
• Bend the three short tabs at the top of the shield inward
to 90° to maintain the 2 in. (51 mm) air space from the
chimney.
• Bend the remaining top tabs to just meet the pipe.
If you wish to make a custom shield or barrier, follow
these guidelines:
• Metal is preferred, although any material stiff enough to
hold back the insulation can be used.

• The shield or barrier must be tall enough to extend
above the insulation and prevent blown-in insulation
from spilling into the cavity.
• Maintain specied air spaces around chimney.
• Check instructions and local codes for further details.

G. Install Attic Insulation Shield
When offsets and returns are joined to straight pipe sec-
tions, they must be locked into position with the screws pro-
vided* (outer only), using the predrilled holes. To prevent
gravity from pulling the chimney sections apart, the returns
and the chimney stabilizers have hanger straps for secur-
ing these parts to joists or rafters. See Figure 8.11 on page
48.
* Use #6 or #8 sheet metal screw, or larger, no longer than
1/2 in. (13mm).
H. Secure the Chimney
