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 51
(page 37), are being maintained. These clearances and those
cited by local and national codes must be maintained.
3. If installing both the intake air and the vent piping in a Direct
Vent configuration through a sidewall; ensure that all exterior
sidewall clearance requirements for the terminations, shown in
Figure 52
(page 38), for the vent and the 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 25
.
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 moisture-laden
air such as clothes dryers. This will reduce
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 vent
terminations must be installed at the same elevation measured
on horizontal center line - see
Figure 25
.

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 25
(page 27).
7. Cut a hole in the wall through which the pipes will pass as
follows:
Pipe Size Hole Size
2" 3" (7.6 cm)
3" 4" (10 cm)
4" 5" (13 cm)
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.
