5.Glue the intake vent terminal to the section of the pipe.

6.Slide the wall plate over the pipe to stop against intake vent terminal.

7.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.

8.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 (See Figure 9).

VERTICAL VENT TERMINAL INSTALLATION

IMPORTANT

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 Figure 10 & 11.

NOTE: Exhaust vent terminal is installed using the same procedure.

INSTALLATION SEQUENCE

NOTE: BEFORE BEGINNING INSTALLATION OF ANY VENT PIPE, READ “VENT PIPE PREPARATION” SECTION ON PAGE 12.

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 1/4" (6 mm) 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 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 11.
