CLEARANCE

A support is required at each change in venting direction, and in any location where it is necessary to maintain the necessary clearance to combustibles. A simple “up and out” installation (Fig- ure 7.3) requires only enough support to maintain the necessary clearance to combustibles. However, the vent at- tachment point and the firestop loca- tion are considered to be supports.
