E. Install the Attic Insulation Shield

WARNING

Fire Risk

•DO NOT pack insulation or other combustibles: between ceiling firestops; between chimney and attic insulation shield.

•ALWAYS maintain specified clearances around chimney and ceiling firestop systems.

•Install ceiling firestops as specified.

Failure to keep insulation or other material away from chimney pipe may cause fire.

An insulation shield must be installed when there is a pos- sibility of insulation coming into contact with the factory built chimney system. Installation of a ceiling firestop is required (see Figures 5.7 and 5.8).

•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 clearance. See Figure 5.6.

•Rest the insulation shield on the ceiling firestop below.

•Bend the three short tabs at the top of the shield inward to 90° to maintain the 2 in. (51 mm) clearance 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 up against 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 specified cleaances around chimney.

•Check instructions and local codes for further details.
