VENT FRAMING
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 5x8 inch diameter pipe and elbows and 1 inch of clearance
on both sides and bottom.
Support vertical runs of this vent systems every 4 feet using wall
brackets attached to the vent pipe and secured with nails or screws
to structural framing.
SEE NOTE
Installing Firestops - Figure 41
Firestops are required for safety whenever the vent system passes
through an interior wall, an exterior wall, or a ceiling. These firestops
act as a firebreak heat shield and as a means to insure that minimum
clearances are maintained to the vent system.
Horizontal Firestops
Horizontal runs in the vent system which pass through either interior
or exterior walls, require the use of wall firestops on both sides of
the wall through which the vent passes.
Position the firestops on both sides of the framed hole, previously
cut. Secure firestop with nails or screws. The heat shields of the
firestops MUST BE placed towards the top of the hole. Continue
the vent run through the firestops.
