IMPORTANT

WHEN LOCATING THE TERMINALS ON A SIDEWALL, THE FOLLOWING

SPECIFICATIONS PERTAINING TO TERMINAL LOCATION MUST BE

FOLLOWED.

1.The intake vent terminal and the exhaust vent terminal must terminate on the same exterior wall and must be located at a minimum of 24" (61cm) from the vertical centerline of the exhaust vent terminal (see Figure 9). In colder climates increasing the 24" (61cm) minimum will reduce possibility of frost over from side winds blowing exhaust vapors to the air intake of the direct the vent.

2.The horizontal centerline of the intake vent terminal may not be located lower than the horizontal centerline of the exhaust vent terminal (see Figure 9).

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

CAUTION

Vent terminals supplied with the heater must be used.

NOTE: BEFORE BEGINNING INSTALLATION OFANY 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.

2.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 holes by 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.

3.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.

4.Cut a length of 3" PVC pipe about 3.5" (8.9 cm) longer than the wall thickness at the opening.

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
