8. Suspend the pipe(s) through center of hole using field

supplied metal strapping or equivalent support materials as

shown in Figure 22 on page 25.

9. Slide a roof boot or equivalent flashing over the pipe and

secure roof boot or equivalent flashing to roof and seal

around the flashing as shown in Figure 22, Figure 23 and

Figure 24 on page 25.

10. Install the factory supplied intake air and/or vent termination(s)

using field supplied pipe and one field supplied 90° elbow as

shown in Figure 22 on page 25. The short section of pipe

that connects between the field supplied 90° elbow and the

factory supplied termination must not be excessive in length.

The exposed portion of this pipe shall be no more than 2

inches (5 cm), see Figure 22 on page 25.

11. Return to Power Vent Installation on page 22 or Direct

Vent Installation on page 23 to complete the installation of

the intake air and/or vent piping between the termination(s)

and the water heater.
