D. Install Attic Insulation Shield

WARNING! Fire Risk. DO NOT allow loose materials or insulation to touch vent. Hearth & Home Technologies Inc. requires the use of an attic shield.

The National Fuel Gas Code ANSI Z223.1 and NFPA 54 requires an attic shield constructed of 26 gauge minimum metal that extends at least 2 in. (51 mm) above insulation.

Attic shields must meet specified clearance and be se- cured in place.

Flat Ceiling Installation

•Remove one shield from box.

NOTICE: 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 three tabs on the bottom of the shield outward to allow attachment to the ceiling firestop.

•Bend the remaining bottom tabs inward 90° to maintain the air space between the pipe and the shield. Set the shield on the ceiling firestop and attach to the firestop.

•Bend all tabs inward 90° around the top of the shield. These tabs must be used to prevent blown insulation from getting between the shield and vent pipe, and to maintain air space clearance.

Vaulted Ceiling Installation

•The attic insulation shield has been laser-etched with ceiling pitch cut lines to make field trimming easier.

•Remove one shield from box.

NOTICE: 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 fit your ceiling pitch. Snip cut edge to recreate 1 in. bend tabs all the way around the bottom.

•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 three tabs on the bottom of the shield outward to allow attachment to the ceiling firestop.

•Bend the remaining bottom tabs inward 90° to maintain the air space between the pipe and the shield. Set the shield on the ceiling firestop and attach to the firestop.

•Bend all tabs inward 90° around the top of the shield. These tabs must be used to prevent blown insulation from getting between the shield and vent pipe, and to maintain air space clearance.
