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 connection 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
Step 3. Center
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 50).
