Proper assembly of air-cooled chimney parts result in an overlap at chimney joints of 1-1/4 in. (32 mm). Effective length is built

into this chart.

• Use an offset/return to bypass overhead obstructions.

• An offset and return can be used as a single entity or separated by chimney section(s).
WARNING! Risk of Fire! DO NOT use offset/returns greater than 30°. Chimney draft will be restricted and could cause over-

heating and fire. Secure offsets vwith screws ( not to exceed 1/2” / 13 mm in length) Secure returns with strapping. Straight

chimney sections may be secured with screws. Keep chimney sections from separating or twisting.

• MeAsuRe the shIFt NeeDeD to AvoID the oveRheAD obstRuctIoN. Refer to dimension A in Figure 8.3.
• Find the appropriate A dimension listed in Table 8.2. The B dimension coinciding with the A dimension measurement in Table

8.2 represents the required vertical clearance needed to complete the offset/return.

• Read across the chart to find the number of chimney sections/model numbers needed between the offset and return.

1-1/4 in. (32 mm)

OVERLAP

Figure 8.3 Chimney Offset/Return

Example:
Your “A” dimension from Figure 8.3 is 14 1/2 in. (368

mm). Using Table 8.2 the dimension closest to, but not

less than 14 1/2 in. (368 mm) is 14 1/2 in. (368 mm) us-

ing a 30° offset/return.
You determine from the table that you need 34 1/8 in.

(867 mm) (Dimension “B”) between the offset and return.
The chimney component that best fits your application is

one SL324.
