InstallatIon sequence
For installations in the City of Los Angeles, California Category IV
PVC Pipe such as that manufactured by Brownline Pipe Company,
must be used as vent pipe material.

NOTE: BEFORE BEGINNING INSTALLATION OF ANY
VENT PIPE READ THE VENT PIPE MANUFACTURER’S
INSTALLATION INSTRUCTIONS.
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 wall. BEWARE OF
CONCEALED WIRING AND PIPING INSIDE OF WALL. If the
vent terminals are being installed on the outside of a finished
wall, it may be easier to mark both the inside and outside
wall. Align the holesby drilling a hole through the center of the
template from the inside through to the outside. The template
can now be positioned on the outside wall using the drilled holes
as a centering point for the template.
A.) MASONRY SIDE WALLS Chisel an opening approximately
1/2” (1.3 cm) larger than the marked circle.
B.) WOODEN SIDE WALLS 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 of the line.
(This will allow the vent pipe to easily slide through
the opening. The resulting gap will be covered by the
vent terminal cover plates.) Repeat this step on the
inside wall if necessary.
2. Cut a length of 3” PVC pipe about 3.5” (8.9 cm) longer than the
wall thickness at the opening.
3. Glue the intake vent terminal to the section of the pipe.
4. Slide the wall plate over pipe to stop against intake vent terminal.
5. Place a bead of caulking (not supplied) around the gap between
the pipe and the wall. Place some of the caulking on the
back of the plate to hold it against the wall after installation.
6. If the vent pipe is installed up to the wall, with a coupling on the
end against the wall opening, the pipe with the vent terminal can
be prepared for gluing before inserting through the wall. Slide the
pipe through the wall and insert into coupling on the other side of
the wall, making sure that the vent terminal ends up pointed in the
correct position (Figure 19).

when terMInatInG throuGh a roof, the followInG
specIfIcatIons pertaInInG to terMInal locatIon
Must Be followed.
1. Proper support must be provided for all pipe protruding through
the roof.
2. The vertical roof terminations should be sealed with a plumbing
roof boot or equivalent flashing.
3. The intake vent termination and the exhaust vent termination must
penetrate the same side of roof.
4. The center line of the intake vent termination and the center
line of the exhaust vent termination must be no closer
than 24” (61cm).
5. The intake vent terminal and the exhaust vent terminal must be
oriented facing downward and the same direction.
The specifications are displayed in Figures 20 & 21.
NOTE: Exhaust vent terminal is installed using the same
procedure.
