VERTICAL, THROUgH THE ROOF
INSTALLATION
• For a typical Vertical Through the Roof
installation, refer to Figures 5 and 6.
Terminate the system 6’ (1.8m) from the
combustion air intake of any appliance.
•Terminate the system at least 3’ (.9m) from
any other building opening, gas utility meter,
service regulator or the like.
•Terminate the system at least 2’ (.61m) above
the roof line and any wall or vertical structure
closer than 8’ (2.4m). Additional support is
required for systems that extend more than 6’
(1.8m) above the roof line.
•Enclose residential exterior vent systems
below the roof line or use FasNSeal® W2
to limit condensation and protect against
mechanical failure.
•Install a Wall Bracket after every transition
from horizontal to a vertical run of over 10’
(3.05m), a minimum of every 12’ (3.66m) of
vertical run, and after any offset in the vertical
run. (See Detailed FNS® Wall
Bracket Installation)
•Unless FasNSeal® is installed in a fire rated
shaft, a fire stop and support is required
when penetrating through each floor/ceiling
level (See Figure 5). A Firestop is not needed
at the roof level.
•The total equivalent vent length from
appliance flue collar to the termination shall
not be greater than specified in the appliance
manufacturer’s installation instructions.
•A FasNSeal® Rain Cap or any other provision
as required by the appliance manufacturer
must be used to keep rain or debris out of the
vent.
1. Locate the path for the vent system.
2. Cut and frame openings in floors and
ceilings to accommodate Firestops.
3. Cut the opening in the roof for the Roof
jack. Cut the opening so that a minimum
distance of 1”/25.4 mm is between the Roof
