Fire Risk
Keep loose materials or blown insulation
from touching the vent pipe.
• National building codes recommend using
attic shield to keep loose materials/blown
insulation from contacting vent.
• Hearth & Home Technologies requires
the use of an attic shield.
WARNING
Flat Ceiling Installation
• Remove one shield from box.
Note:
Cut previously installed batt insulation to make room
for the attic insulation shield.
• 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.
• Bend four tabs inward on bottom of shield where it rests on
the ceiling
¿
restop to maintain the air space between the
pipe and shield. Set the shield on the ceiling
¿
restop.
• 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.
Vaulted Ceiling Installation
• The attic insulation shield has been laser-etched with cut
lines and ceiling pitches to make
¿
eld trimming easier.
• Remove one shield from box.
Note:
Cut previously installed batt insulation to make room
for the attic insulation shield.
• Cut the attic insulation shield (if application is for vaulted
ceiling) using a laser-etched cut line, to
¿
t 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.
• Bend four of the remaining tabs inward 90° on bottom
of shield to maintain the air space between the pipe and
shield. Cover the resulting holes with aluminum tape. Set
the shield on the ceiling
¿
restop.
• 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.
