E. Install the Attic Insulation Shield

An insulation shield must be installed when there is a pos- sibility of insulation coming into contact with the factory built chimney system.

•Bend the tabs at the top of the attic insulation shield inward. This will help keep the chimney section centered in the shield.

•Position the shield over the vertical chimney section where it penetrates a ceiling ﬁrestop.

•Slide the shield down until it rests on the ceiling ﬁrestop. The ceiling ﬁrestop will support the insulation shield. See Figures 5.6 and 5.7.

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.

F. Double-check the Chimney Assembly

Continue assembling the chimney sections up through the ceiling ﬁrestops as needed. While doing so, be aware of the height and unsupported chimney length limitations given un- der Section 5.A. Chimney Requirements.

Check each section by pulling up slightly from the top to en- sure proper engagement before installing the succeeding sections. If they have been connected correctly, they will not disengage when tested.

When offsets and returns are joined to straight pipe sections, they must be locked into position with the screws provided* (outer only), using the predrilled holes. To prevent gravity from pulling the chimney sections apart, the returns and the chimney stabilizers have hanger straps for securing these parts to joists or rafters. See Figure 5.8.
