Attic Insulation Shield:
The Attic Insulation Shield must
be installed where the chimney passes into an attic. Its
purpose is to maintain clearances from loose packed or
blown insulation from the chimney. If an Attic Shield is not
used the chimney needs to be enclosed within a framed
enclosure. Always maintain a 2” air-space clearance to
combustibles. Install the shield as follows:
•
Remove any insulation or debris from attic floor around
the framed opening.
•
Assemble chimney sections above the Firestop to
a height that extends beyond the height of the attic
insulation shield.
•
Slip the Attic Insulation Shield over the chimney until
the base sits squarely on the framed opening.
•
Secure the Attic Insulation Shield to the top of the
framed opening using nails or screws. See
FIG. 8
.
Termination:
NFPA 211, “Standard for Chimneys,
Fireplaces, Vents, and Solid Fuel-Burning Appliances”,
states that chimneys shall extend at least three feet above
the highest point where it passes through the roof of a
building, and at least two feet higher than any portion of a
building within ten feet. See
