diameter PVC pipe. When venting with 4" (10.2 cm) PVC, use a 4" (10.2 cm) to 3" (7.6 cm) reducer to exit through the building wall with 3" (7.6 cm) PVC. Use the 3" (7.6 cm) vent terminal supplied with the water heater to terminate on the outside of the building. If the length of 3" (7.6 cm) PVC needed to go through the wall is greater than 14" (35.5 cm), use 4" (10.2 cm) to go through the wall and reduce to 3" (7.6 cm) PVC immediately after exiting the outside wall. Refer to the venting illustrations on the following pages. Make sure the vent pipe terminal elbow fitting is at least 1" (2.5 cm) away from the edge of the wall.

IMPORTANT

All of the Venting connections must be leak checked with a soap and water solution upon initial start up of the water heater. Any leaks must be repaired before continuing operation of the water heater.

NOTE: ABS or CPVC pipes may be substituted for PVC pipe. Do not mix ABS and PVC pipe in the same installation.

THROUGH THE WALL VENTING:

Cut a 3-1/2 inch (8.9 cm) diameter hole in the wall at the point where the vent connector is going to pass through the wall. Use the proper cement to secure the 90° vent terminal provided with the water heater to the vent connector. The distance between the edge of the 90° vent terminal and the exterior wall (see Figure 3) must be 1 inch (2.5 cm). Use the proper cement and assembly procedures to secure the vent connector joints between the terminal and the blower outlet. Provide support brackets for every 3 feet (.91 m) of horizontal vent.
