FRAMING AND FINISHING
Installing Support Brackets
Install a horizontal pipe support used for each 3 feet of horizontal
run to framing members. Allow 3 inches of clearance to
combustibles above 8-inch diameter pipe and elbows, and 1 inch
of clearance to both sides and bottom.
Support vertical runs of this vent systems every 4 feet using wall
brackets attached to the vent pipe, then secured with nails or
screws to structural framing.

Installing Firestops
Firestops are required for safety whenever the vent system passes
through a wall or a ceiling. These firestops act as a firebreak heat
shield and as a means to ensure minimum clearances.
Horizontal Firestops
Horizontal runs require firestops on both sides of the wall.
Position the firestops on both sides of the framed hole.
See
Figure 59.
Secure firestop with nails or screws. Continue the
vent run through the firestops.
