Sidewall Termination Installation
1. Determine the location for the termination(s). |
2. If installing only vent (exhaust) piping in a Power Vent |
configuration through a sidewall; ensure that all exterior |
sidewall clearance requirements for the termination, shown |
in Figure 48 on page 34, are being maintained. These |
clearances and those cited by local and national codes must |
be maintained. |
3. If installing both intake air and vent piping in a Direct Vent |
configuration through a sidewall; ensure that all exterior |
sidewall clearance requirements for the terminations, shown |
in Figure 49 on page 35, for the vent and intake air termination |
are being maintained. These clearances and those cited by |
local and national codes must be maintained. |
4. If installing both an intake air and vent termination in a |
Direct Vent configuration through a sidewall there must |
be a minimum of 24 inches (61 cm) separation, measured |
on vertical center line, between the intake air and vent |
terminations, see Figure 22. |
Note: In colder climates this separation should be increased |
to at least 48 inches (122 cm) between the intake air and |
vent termination or any other appliance vent that discharges |
possibility of frost over from side winds blowing exhaust |
vapors to the intake air termination and is recommended for |
Canadian installations. |
5. If installing both intake air and vent terminations in a Direct |
Vent configuration through a sidewall the intake air and |
(18 cm) diameter hole for 6 inch pipe where the pipe(s) will pass through the wall.
Note: Beware of concealed wiring and piping when cutting through the wall.
8.Cut a length(s) of pipe being installed 3.5 inches (8.9 cm) to 9.5 inches (24.1 cm) longer than the wall thickness at the opening. See Figure 23.
Note: Vent Termination – exhaust gases of this water heater are less than 140°F. In cold climates water vapor in the exhaust gases will condense into a cloud of vapor where the vent exits the building. This vapor can gradually discolor exterior building surfaces. The vent termination should be located where this vapor cloud and potential discoloration are not a concern. Extending the exposed vent piping up to a maximum of 6 inches (15.2 cm) from the wall helps vapor from being trapped along a building’s face. To avoid this problem, the vent can also be terminated vertically through the roof, see Vertical Termination Installation on page 24.
9.Cement the intake air and/or vent termination to the section(s) of pipe cut to length in the above Step.
10.Slide the included metal wall plate(s) over the pipe(s) to stop against the intake air and/or vent termination. Place some silicone caulking (field supplied) on the back of the wall plate(s) to secure it to the wall.
11.Working from outside, slide the pipe and termination(s) assembled in the above steps through the wall. Ensure the termination(s) is pointed down towards the ground. See Figure 23.
vent terminations must be installed at the same elevation |
measured on horizontal center line - see Figure 22. |

6.When the intake air and/or vent piping from multiple water heaters will terminate at the same location through a sidewall, the vent terminations can be grouped together in close proximity - 0 inches/touching. The intake air terminations can also be grouped together in close proximity - 0 inches/ touching.
However, the distance between the closest vent and intake air terminations must be a minimum of 24 inches (61 cm). In colder climates this separation should be increased to at least 48 inches (122 cm). See Figure 22.

12.Place a bead of silicone caulking (field supplied) around the gap between the installed pipe(s) and the wall. Apply enough to fill the gap between the pipe(s) and wall.
13.Press the wall plate flush against the outside wall.
14.Working from the inside apply enough silicone caulking on the back of the interior wall plate(s) to hold it in place and slide the wall plate over the installed pipe(s).
15.Install a coupling to the end of the pipe(s) inside the building. Before the silicone caulking has time to completely set go outside the building and ensure the termination(s) is still pointing down towards the ground. See Figure 23.
16.Return to Power Vent Installation on page 23 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.
