D. Assemble the Chimney Sections
Use only those components described in this manual.
Substitute or damaged chimney components could impair safe operation and cause overheating and fire.
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 be- low it. The outer casing is placed outside the outer casing of the chimney section below it. See 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 (provid- ed) 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).
