flue of the fireplace, midpoint between two joists to prevent
having to cut them. use a plumb bob to line up the centre.

minimum clearance of 2" between the outside of the chimney
and any combustible material. dO NOT FIll ThIS SpACE
WITh ANY TYpE OF mATERIAl! Nail headers between
the joists for extra support. Firestop spacers must be placed
on the bottom of each framed opening in any floor or ceiling

mine where the opening in the roof should be. Cut and frame
the roof opening maintaining proper 2" clearances.

Add chimney sections, twist locking (clockwise) securely, to
the required height. use a rafter radiation shield whenever
the chimney system is enclosed within an attic area.
The first flue offset closest to the top of the unit
must be a minimum distance of 12" from the top
of the fireplace.
An insulated elbow must be used when it becomes neces-
sary to offset the chimney in order to clear a joist or to pass
through an upstairs closet.
Attach an elbow to the chimney section, angled toward the
offset. Secure with - #8X1/2" sheet metal screws. To achieve
the minimum offset, attach and secure a return elbow to the
first. To achieve longer offsets, you may install any available
length of chimney pipe between the elbows.
Supports must be used on the first vertical chimnney section
after a return elbow.
