I. Install Attic Insulation Shield

The Attic Insulation Shield must be installed where the chimney passes into an attic. Its purpose is to prevent debris and insulation from getting too close to the chimney. In attic areas where this shield cannot fit, or is not used you must enclose the attic portion of the chimney in a framed enclosure. If the chimney is fully enclosed through the attic, an Attic Insulation Shield is not required. Install the Attic Insulation Shield as follows:

•Remove any insulation from attic floor around the framed opening.

•Assemble Chimney Sections until at least 18 inches of chimney extends above the Firestop.

•Slip the Attic Insulation Shield over the chimney until the base sits squarely on the framed opening (Figure 8.8).

•Secure the Attic Insulation Shield to the top of the framed opening using at least (2) 8-penny nails or (2) #8, 1-1/2 in. wood screws per side (Figure 8.9).

•Wrap the Collar of the Attic Insulation Shield around the chimney and fasten it loosely. Slide the Collar down to meet the Attic Insulation Shield. Tighten the bolts to secure the Collar in place (Figure 8.9).

J. Install Roof Radiation Shields

Roof Radiation Shields provide protection for roof framing members. Note: Roof Radiation Shields do not allow for a reduced clearance to combustibles. Clearance to com- bustibles must be a minimum of 2” away from the chimney pipe. When you penetrate through the roof, Roof Radiation Shields must be installed with a 1/2” air gap between the shields and the joist face (Figure 8.10). Depending on the pitch of your roof, trim the Roof Radiation Shields with tin snips so they provide coverage of the roof framing ex- posed to the chimney. Secure the Roof Radiation Shields to the top of the framing members using at least (3) nails or screws for each shield (Figure 8.10).
