Vertical venting
(see figure 6/b - 6/d)
NOTE: The vent termination must be at
least 3 ft. (1 m) to a maximum of 6ft. above
the roof line and 2 ft. (.61 m) higher than
any part of a structure within 10 ft. (3. 1 m).
The total vertical distance of the vent
system from appliance flue collar to the rain
cap termination and the maximum length of
offsets shall not exceed that specified in the
appliance manufacturer's
instructions. No continuous vertical run
shall be longer than sixty feet (18.3 m). All
horizontal sections must observe the rules
for HORIZONTAL VENTING. The clearance
to combustibles inside a chase shall be no
less than 4" (100 mm).
1. Prior to beginning the installation loo-
sely assemble all parts required to
make sure all parts are present.
2. Locate position for venting system and
proceed to cut holes for firestop sup-
port and firestop spacers. All vertical
installations require the use of a sup-
port. Frame the opening of the floor
using lumber, which is dimensionally
consistent with the structural mem-
bers. Insert the support from beneath
the framed opening and secure with
nails or screws as required.
3. Refer to JOINT PROCEDURE (figure 6)
before assembling system.
4. Install system joining pipe as required
up through roof (illustration page 25).
Tighten gear clamp on firestop support
to hold vent system. NOTE: A firestop
must be provided when a vent passes
installation through a combustible floor or ceiling.
The opening must be framed for the
support since the support also serves
as a firestop.
5. The roof flashing can now be installed.
Where the vent passes through the
roof a flashing must be used to main-
tain the required clearances and to
protect from the elements. The framed
opening must be large enough to provi-
de the necessary clearances to combu-
stibles, taking into account the slope of
the roof. The flashing can be used on
slopes from flat to 6/12 pitch. Install
the flashing while holding the pipe cen-
tered in the opening. Fasten the fla-
shing to the roof under the roofing
material upslope from the pipe and
above the roofing material below the
pipe. Seal as required using high tem-
perature silicone.
6. Install Top Support around pipe and
against flashing collar. (figure 6/b, 6/d,
6/e, 6/c)
7. Attach rain cap using. JOINT PROCE-
DURE (figure 6)
8. The vertical section is connected by an
elbow joined to the horizontal run and
then through a drain tee (see page 4
for details) to the appliance. Elbows are
joined to pipe using the JOINT PROCE-
DURE (figure 6).
NOTE: If there is no solid anchor point in the
system below the roof (ie Firestop Support
etc.) then a Z-Vent Guy Band must be used
below the roof as follows. (see figure 6/c)
a. Attach the Guy Band at any point above
an elbow or tee in the vertical section
within 20 feet of the roof.
b. Fasten stainless steel or galvanized
cable with a minimum capacity of 500
lbs. to each of the four anchor holes.
c. Anchor the cables to a rigid building
member using an appropriate fastening
method.
