C. Assemble Chimney Sections
WARNING! Risk of Fire! DO NOT install substitute or dam- aged 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).
