Assemble The Chimney Sections; Installing Cak4A And Flex Pipe - Heat & Glo NORTHSTAR-BK Owner's Manual

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).
