B. Assemble 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 5.2.
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.
•
Fasten offset/returns to chimney sections. 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).
