FRAMING AND FINISHING
Install Support Brackets
A horizontal pipe support MUST BE used for each 3 feet of
horizontal run. Place the pipe supports around the pipe and nail
in place to framing members. There MUST BE a 3-inch clearance
to combustibles above 6-5/8 inch diameter pipe and elbows and
1-inch clearance on both sides and bottom of 6-5/8 inch pipe to
combustibles on all horizontal pipe sections and elbows.
Support vertical runs of this vent system every 4 feet above the
fireplace flue outlet with wall brackets attached to the 6-5/8 inch
vent pipe and secure with nails or screws to structural framing
members.

Install 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. See Figure 47. Secure firestop with nails or screws.
Continue the vent run through the firestops.
