INSTALLING OFFSETS
First, review the Offset Elevation Chart and
Figure 21 for reference.
Step 1. Determine the offset distance where
chimney is to pass through the first
ceiling-dimension "A." To find this
point on your ceiling, first determine
the center point for a vertical chimney
following the instructions for vertical
installation.
Measure height to the ceiling from the
top of fireplace-dimension "B." Use
the appropriate Offset Elevation Chart
to find 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 flue. Check connec-
tion by pulling up slightly to ensure a tight fit.
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 flue
pipe-slip down.
Step 3. Center outer-locking section over outer
chimney pipe. Push down until locking
B
joint has firmly engaged.
Step 4. Pull up slightly on return elbow to ensure
locking joint has firmly engaged.
Step 5. Secure support straps to framing
members by nailing under tension in
sheer (Figure 22).

Notes:
• The return elbow assembly performs the
same function as a stabilizer. Consider this
when determining the need for a stabilizer.
• Do not apply excessive pressure to any
subsequent chimney section following return
elbow assembly when installing. Ensure that
each subsequent chimney section is securely
attached by testing as noted above.
