VENTING INSTALLATION
1. Flat Ceiling Installation
• Remove one shield from box.
• Wrap shield around pipe if pipe is already installed
in area to be insulated.
• Match the three holes in each side and fasten with
three screws to form a tube.
• One or more tabs may be folded outward on the
bottom of the shield to allow attachment to ceiling
firestop.
• Bend remaining tabs inward on bottom of shield
where it rests on the ceiling firestop to maintain
the air space between the pipe and shield. Set the
shield on the ceiling firestop.
• Bend all tabs inward 90° around the top of the
shield. These tabs must be used to prevent blow-in
insulation from getting between the shield and vent
pipe, and to maintain clearance.
2. Vaulted Ceiling Installation
• Remove one shield from box.
• Cut the attic insulation shield (if application is for
vaulted ceiling) using a laser-etched cut line, to
fit your ceiling pitch. Snip cut edge to create three
bend tabs.
• Wrap shield around pipe if pipe is already installed
in area to be insulated.
• Match the three holes in each side and fasten with
three screws to form a tube.
• One or more tabs may be folded outward on the
bottom of the shield to allow attachment to ceiling
firestop.

26 GAUGE MINIMUM METAL THAT EXTENDS AT
LEAST 2 IN.

Attic shields must meet specified clearance and be
secured in place.

where it rests on the ceiling firestop to maintain the
air space between the pipe and shield. Set the shield
on the ceiling firestop.
