SUPPORT SECTIONS

The  chimney  support  section  is  a  4"  strap 

and 12" length of pipe. A chimney support is 

required every 30 feet above fireplace after a 

straight chimney run or above a return elbow 

after a straight chimney run (see Figure 16). 

This support is designed to relieve the extra 

weight load on firebox and elbows when high 

chimneys are installed.

ELBOW OFFSET INSTALLATION

Chimney weight above offset rests on return 

elbow.  Straps  must  be  securely  nailed  to 

rafters or joists (see Figure 17).

To  achieve  desired  offset,  you  may  install 

combinations of 12", 18", 36" and 48" length 

of  double  wall  pipe  (see  offset  chart  and 

Figure 18).
