K. 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 8.10).

•Secure the attic insulation shield to the top of the framed opening using at least two 8-penny nails ort wo #8, 1‑1/2 in. wood screws per side (Figure 8.11).

•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 8.11).

L. Install Roof Radiation Shields

Roof radiation shields must be used to provide protection for roof or chase framing members.

Note: Roof radiation shields do not allow for a reduced clearance to combustibles.

Clearance to combustibles must be a minimum of 2” away from the chimney pipe.

•Install roof radiation shields at either the top of the chase or where the chimney penetrates the roof, whichever is the top of the installation.

•Roof radiation shields are built with a 1/2” air gap standoff from the joist face (Figure 8.12). The corners of the roof radiation shields overlap each other to ensure proper position.

•Secure the roof radiation shields to the top of the framing members using screws or nails in the corners.

•If framing members are further away from the chimney than 2 in., center the roof radiation shield to the chimney on the framing member and secure in place with screws or nails.

M. Attach Flashing

For chase enclosures, use the Chase Top Flashing. The Chase Top Flashing allows for a 1-1/2 in. clearance main- tained from the chimney (Figure 8.14) and provides re- quired ventilation air.

•Chase Top Flashings (includes Chase Top Collars and Spacing Clips) are available from your HHT dealer.

•Additional non-combustible structural supports can be field-fabricated to help support the Chase Top Flashing if needed, provided the air ventilation requirements are maintained. See Figure 8.15.

•If the ChaseTop Flashing (40 in. x 40 in.) does not ensure the minimum 1/2 in. spacing and perimeter ventilation requirements as shown in Figure 8.13., use a Chase Top Collar and field-construct the flashing as needed for the chase dimensions. Skip to Field-Constructed Chase Top Flashing.
