B. Offsets/Returns

•  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 

overheating and fire. Secure offsets with 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 4.2.

•  Find the appropriate A dimension listed in Table 4.3. The B dimension coinciding with the A dimension measurement in 

Table 4.3 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.
