SUPPORT SECTIONS

The chimney support section is a 4-inch strap and 12 inch length of pipe. A chimney support is required every 30 feet above the fireplace after a straight chimney run, or above a return elbow after a straight chimney run (see Figure 20). This support is designed to relieve the extra weight load on the fireplace and elbows when high chimneys are installed.

To achieve desired offset, you may install combinations of 12, 18, 36, and 48 inch lengths of double wall pipe. See Figure 21 and Rise and Offset Chart below.
