OFFSET CHART (22-50 FT. SYSTEM HEIGHT)

2.Chimney weight above offset rests on return elbow. Straps must be securely nailed to rafters or joists (see Figure 8, details a and b).

3.Maximum length of pipe between supports (return elbow or 12S-12DM) is 6' of angle run. Maximum of two 6' angle run sections per chimney system (see Figure 7).

4.All pipe connections between the offset and return must be secured with two screws on the outer pipe only (see Figure 9, page 10). Do not penetrate the inner stainless.
