Installing the water heater.
Vertical Vent Installation
Once the vent terminal location has been
determined, make a hole through the roof
and interior ceiling to accommodate the
vent pipe. Complete the vent pipe
installation to the water heater's vent
connector fitting on the water heater vent
collar outlet. Support vertical or horizontal
runs as previously mentioned. If required,
use silicone sealant at the point the vent
connector joins the water heater. Install adequate flashing where the vent
pipe passes through the roof. Determine
the vent terminal height and install the
vent pipe accordingly. Refer to the
illustration above for proper vent terminal
height. Connect vent elbow on to vertical
pipe through roof. Connect short piece of
vent pipe (approximately 6" long (15 cm))
to elbow, and the terminal elbow with the
protective screen.

Vertical Vent Termination Location
The location of the vent terminal depends on the following
minimum clearances and considerations (see illustration):
Minimum twelve (12) inches (30 cm) above roof.
Minimum twelve (12) inches (30 cm) above
anticipated snow level.
Maximum twenty-four (24) inches (60 cm) above
roof level without additional support for vent.
Four (4) feet (1 m) from any gable, dormer or other
roof structure with building interior access (i.e., vent,
window, etc.).
Ten (10) feet (3 m) from any forced air inlet to the
building. Any fresh or make-up air inlet such as a
dryer or furnace area is considered to be a forced air
inlet.
