Step 1.
Determine the offset distance where
chimney is to pass through the fi rst
ceiling-dimension “A.” To fi nd this
point on your ceiling, fi rst determine
the center point for a vertical chimney
following the instructions for vertical
installation.
Measure height to the ceiling from the
top of fi replace-dimension “B.” Use the
appropriate Offset Elevation Chart to fi nd
dimension “A.” Mark point where you
will drive your nail to show the center
point for your offset ceiling cut.
Step 2.
Proceed by using the Straight Up In-
stallation Instructions for cutting and
framing ceiling and roof openings.
Note:
See Framing and Dimension Chart for
the sizes of the ceiling and roof openings. The
size of the roof opening varies with the degree
of pitch of the roof.
Offset Elbow Assembly
Offset elbows install the same as chimney
sections. First, snap the inner section INTO the
preceding inner section of fl ue. Check connec-
tion by pulling up slightly to ensure a tight fi t.
Next, the outer sections snap lock OVER the
preceding outer section of chimney. Again,
check outer section by pulling up slightly to
ensure proper connection is made.
Return Elbow Assembly
Return elbows install the same way as round
terminations and stabilizers:
Step 1.
Hold return elbow over top of last
chimney section.
Step 2.
Center inner slip section into inner fl ue
pipe-slip down.
Step 3.
Center outer-locking section over outer
chimney pipe. Push down until locking
joint has fi rmly engaged.
Step 4.
Pull up slightly on return elbow to ensure
locking joint has fi rmly engaged.
Step 5.
Secure support straps to framing
members by nailing under tension in
sheer (
Figure 50
).
INSTALLING OFFSETS
First, review the Offset Elevation Chart and
Figure 49
for reference.
