Installing Support Brackets
Install a horizontal pipe support for each 3 feet of horizontal run
to framing members. Allow a 1 inch clearance to combustibles
above the 6-inch diameter pipe and elbows and 1 inch clearance to
both sides and bottom.
Support vertical runs of this vent system every 4 feet using wall
brackets attached to the vent pipe, then secured with nails or
screws to structural framing.

VENT FRAMING AND FINISHING
Installing Firestops
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. Continue
the vent run through the firestops.
