13.Ensure the Balance Plate and Intake Air Screen on the Intake Air Connection are both removed before connecting the intake air pipe to the water heater, see Figure 17.

Breathing Hazard - Carbon Monoxide Gas

Do not obstruct water heater air intake.

Gas and carbon monoxide detectors are available.

Install water heater in accordance with the instruction manual.

Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.

Note: Do not leave the screen inside the Intake Air connection in Direct Vent installations. Once the intake air pipe is installed the screen will be hidden from view and may become clogged with debris over time. This will cause improper combustion.

Vertical Termination Installation

1.Determine the location for the termination(s).

2.If installing only the vent (exhaust) piping in a Power Vent configuration vertically through the roof; ensure that all exterior vertical clearance requirements shown in Figure 19 and Figure 20 on page 25 are being maintained. These clearances and those cited by local and national codes must be maintained.

Note: On flat roof installations the vent termination must be a minimum of 24 inches (60 cm) above any parapet, vertical wall or structure within 10 feet (3 m) horizontally. See Figure 20 on page 25.

3.If installing both intake air and vent piping in a Direct Vent configuration vertically through the roof; ensure that all exterior vertical clearance requirements shown in Figure 19 and Figure 20 on page 25 are being maintained. These clearances and those cited by local and national codes must be maintained.

Note: On flat roof installations the intake air and the vent terminations must be a minimum of 24 inches (60 cm) above any parapet, vertical wall or structure within 10 feet (3 m) horizontally. See Figure 20 on page 25.

4.If installing only vent piping in a Power Vent configuration vertically through the roof the following instructions must be followed:

The vent termination must be oriented facing downward as shown in Figure 19 and Figure 20 on page 25.

The bottom edge of the vent termination must be a minimum of 12 inches (30 cm), 18 inches (45 cm) in Canada, above the average or expected snow level as shown in Figure 19 on page 25.

5.If installing both intake air and vent piping in a Direct Vent configuration vertically through the roof the following instructions must be followed:

The intake air and vent pipes must penetrate the same side of the roof as shown in Figure 21 on page 25.
