E93.1801EN171 HWB installation manual 57
Two pipes vertical termination of air and vent.
8. Locate terminations so they are not likely to be damaged by foreign objects, such as stones or balls, or subject
to buildup of leaves or sediment.
Multiple vent/air terminations
1. When terminating multiple water heaters, terminate each vent/air connection as described in this manual (figure
below).
Terminate all exhaust vent pipes at the same height and all air intake pipes at the same height
to avoid recirculation of flue products and the possibility of severe personal injury, death,
or substantial property damage.
2. Place roof penetrations to obtain minimum clearance of 12 inches (305 mm) between
outside edge of air intake
an exhaust vent
of another water heater for U.S. installations (see figure below). For Canadian installations,
provide clearances required by CSA B149.1 Installation Code.
Vertical terminations with multiple water heaters.
Note: keep the terminals at min. 12" above grade or snow line. Provide exhaust vent and air intake with bird screen.
