C. Assemble the Chimney Sections

Attach either a straight chimney section or an offset to the top of the fireplace (depending on your installation require- ment). Chimney sections are locked together by pushing downward until the top section meets the stop bead on the lower section.

The inner flue is placed to the inside of the flue section below it. The outer casing is placed outside the outer casing of the chimney section below it. See Figure 5.4.

Figure 5.4 Assembling Chimney Sections

Note: Inner flue and outer liner sections cannot be disas- sembled once locked together. Plan ahead to ensure the proper installation height is achieved with the selected chimney components.

WARNING

Fire Risk

Do NOT install substitute or damaged chimney components.

•MUST use chimney system described in this manual.

•NO OTHER chimney components may be used.

Substitute or damaged chimney components may impair safe operation.

D. Install the Ceiling Firestops

•Mark and cut an opening in the ceiling for the ceiling firestop being used. See Figure 5.5.

•Frame the opening with the same size lumber used in the ceiling joists.

•Install the ceiling firestop.

Note: The ceiling firestop MUST be nailed to the bottom of the ceiling joists EXCEPT when the space above is uninsulated and the attic insulation shield is not being used (see Figure 5.5). When the attic insulation shield is used the ceiling firestop may be above or below the joist of an insulated ceiling.

Figure 5.5 Installing the Ceiling Firestop

Note: You must provide support for the pipe during con- struction and check to be sure inadvertent loading has not dislodged the chimney section from the fireplace or at any chimney joint.

CAUTION

•Ceiling firestops must be used at ceiling/floor.

•Chase construction requires ceiling firestops at each floor or every 10 ft (3.05 m) of clear space.

•Use same dimensional lumber as joists.

Ceiling firestop slows spread of fire and reduces cold air infiltration.
