Hearth and Home Technologies RH-36 Series owner manual Using Offsets/Returns, Example

Page 26

B. Using 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.

•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.

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) using 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 applica- tion is one SL324.
