FIGURE 6
VERTICAL VENT TERMINAL INSTALLATION
IMPORTANT
THIS UNIT CONSISTS OF TWO VENT TERMINALS - AN INTAKE
VENT TERMINAL AND AN EXHAUST VENT TERMINAL. THE
INTAKE VENT TERMINAL IS A 45 DEGREE PVC ELBOW WITH
A DIVERTER PLATE AND SCREEN ADAPTER WHILE THE
EXHAUST VENT TERMINAL IS A 45 DEGREE ELBOW WITH A
MESH WIRE SCREEN.
IMPORTANT
WHEN TERMINATING THE TERMINALS THROUGH A ROOF,
THE FOLLOWING SPECIFICATIONS PERTAINING TO
TERMINAL LOCATION MUST BE FOLLOWED.
1.
In no case should the air intake termination or the exhaust
termination extend more than 24" above the roof penetration.
2.
Must provide proper support for all pipe protruding through
roof.
3.
The vertical roof terminations should be sealed with a
plumbing roof boot or equivalent flashing.
4.
The intake vent termination and the exhaust vent termination
must penetrate the same side of roof.
5.
The centerline of the intake vent termination and the
centerline of the exhaust vent termination must not be closer
than 16" and not farther away than 24".
6.
The intake vent terminal and the exhaust vent terminal must
be oriented facing downward and the same direction.
The specifications are displayed in figure 7.

INSTALLATION SEQUENCE
NOTE:
BEFORE BEGINNING INSTALLATION OF ANY VENT
PIPE, READ “VENT PIPE PREPARATION” SECTION
ON PAGES 12-14.
1.
After the points of termination have been determined, use
the cover plates as templates to mark the holes for the vent
pipes to be inserted through the roof.
2.
Drill a pilot hole approximately one quarter inch outside of
the marked circle. This pilot hole is used as a starting point
for a saws-all or sabre saw blade. Cut around the marked
circle staying approximately one quarter inch outside the line.
(This will allow the vent pipe to easily slide through the
opening). The resulting gap will be covered up by the roof
boot/flashing.
3.
Suspend the pipe through the center of the hole using proper
support.
4.
Slide roof boot or equivalent flashing over pipe and secure
roof boot equivalent flashing to roof.
5.
Seal around flashing.
6.
Terminate intake terminal and exhaust vent terminal facing
down as shown in figure 8.
