OFFSET CHART (22-50 FT. SYSTEM HEIGHT)
Figure 9 - Elbow Offset
USING ELBOW OFFSETS (30E-12DM)
1. To achieve desired offset, you may install combinations of 12",
18", 24", 36" and 48" length of double wall pipe (see offset chart
and Figure 9).
2.
Chimney weight above offset rests on return elbow. Straps must
be securely nailed to rafters or joists (see Figure 10, 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 11, page 10).
4. All pipe connections between the offset and return must be secured
with two screws on the outer pipe only (see Figure 10). Do not
penetrate the inner stainless.
