F. Install Attic Insulation Shield

WARNING! Risk of Fire! You MUST install an attic insu- lation shield when there is any possibility of insulation or other combustible material coming into contact with the chimney.

•DO NOT pack insulation between the chimney and the attic insulation shield.

•Failure to keep insulation and other materials away from chimney pipe could cause ﬁre.

•DO NOT offset chimney inside insulation shield.

Installation of a ceiling ﬁrestop is required

•Refer to Figures 8.6 - 8.8.

•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 air space (refer to Figure 8.6).

•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) air space 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 back the insulation can be used.

WARNING! Risk of Fire! Use of cardboard or other materials that can deﬂect under humidity or other envi- ronmental conditions is not recommended.

•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 air spaces around chimney.

•Check instructions and local codes for further details.
