Hearth and Home Technologies NorthStar-GT, NorthStar-NT owner manual Using Offsets/Returns, Example

Page 21

C. Using Offsets/Returns

To bypass any overhead obstructions, the chimney may be offset using an offset/return.

An offset and return may be attached together or a chimney section(s) may be used between an offset and return.

Perform the following steps to determine the correct chim- ney component combination for your particular installation:

WARNING

Fire Risk

DO NOT combine offsets to create an offset greater than 30° from vertical.

•Draft will be restricted.

•Measure how far the chimney needs to be shifted to enable it to avoid the overhead obstacle. See Figure 21.2. Use dimension “A” to determine chimney section required to achieve the needed shift.

•After determining the offset dimension, refer to Table 21.1 and find the “A” dimension closest to but not less than the distance of shift needed for your installation.

•The “B” dimension that coincides with the “A” dimension represents the required vertical clearance that is needed to complete the offset and return.

•Read across the chart and find the number of chimney sections required and the model number of those particular chimney parts.

•Whenever the chimney penetrates a floor/ceiling, a ceiling firestop must be installed.

•The effective height of the fireplace assembly is measured from the base of the fireplace.

Example:

Your “A” dimension from Figure 21.2 is

14 1/2 in. (368 mm). Using Table 21.1

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. It is

then determined from the table that you

would need 34 1/8 in. (867 mm) (Dimen-

sion “B”) between the offset and return.

The chimney component that best fits

your application is one SL324.
