C. Assembling Chimney Sections

WARNING! Risk of Fire! DO NOT install substitute or damaged chimney components.

•Use only those components described in this manual.

Substitute or damaged chimney components could impair safe operation and cause overheating and fire.

•Support the pipe during construction and check to be sure inadvertent loading has not dislodged the chimney section from the fireplace or at any chimney joint.

•Attach a straight chimney section or an offset to the top of the fireplace.

•Place inner flue to the inside of the chimney section below it. Place the outer casing outside the outer casing of the chimney section below it. Refer to Figure 8.4.

NOTICE: Chimney sections cannot be disassembled once locked together. Plan ahead!

•Lock chimney sections and/or offsets/returns together by pushing downward until the top section meets the stop bead on the lower section.

•Pull on the top section to make sure it is fully engaged and will not separate.

•You may use #6 or #8 sheet metal screws no longer than 1/2 in. (13 mm) to fasten chimney sections together. Do not penetrate inner flue.

WARNING! Risk of Fire! You MUST use screws (pro- vided) to fasten offset/returns to chimney sections to keep the chimney parts from twisting. Failure to do so could cause fire.

•Fasten offset/returns to chimney sections. Insert the screws (provided) through the predrilled holes. Do not penetrate inner flue.

•Secure chimney returns with hanger straps provided; fasten to studs or joists.

•Vertical straight runs of chimney must be supported every 35 ft (10.7 m).

•Required in Canada.

•Follow instructions provided with this accessory.

E. Installing Ceiling Firestops

CAUTION! Risk of Fire! Ceiling firestops must be used whenever the chimney penetrates a ceiling/floor.

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

•The ceiling firestop slows spread of fire and reduc- es cold air infiltration.

•Install a ceiling firestop whenever chimney penetrates ceiling/floor.

•Mark and cut an opening in ceiling as shown in Figure 8.5.

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

•Nail the ceiling firestop to the bottom of the ceiling joists when there is a room above.

•Use an attic insulation shield if the ceiling is insulated. The ceiling firestop may then be attached above or below the joists.

WARNING! Risk of Fire! DO NOT seal area between firestop opening and chimney pipe. Restricting air flow around chimney may cause fire.
