VENT TERMINATION
WARNING: Improper installation can cause nausea or asphyxiation, severe injury
or death from carbon monoxide and flue gases poisoning. Improper installation
will void product warranty.
The vent termination provides a means of installing vent pipe through the building wall and
must be located in accordance with ANSI Z223.1/NFPA 54, or in Canada with CAN/CSA-
B149.1 and local applicable codes.
A proper sidewall vent termination is recommended when the water heater is vented through
a sidewall. If the water heater is converted to a direct-vent unit, a proper sidewall direct-vent
termination is to be used.
General rules for venting the water heater are:
1.
Place the water heater as close as possible to the vent termination.
2.
The vent collar of the water heater must be fastened directly to an unobstructed vent pipe.
3.
Do not weld the vent pipe to the water heater collar.
4.
Do not cut the vent collar of the unit.
5.
The weight of the vent stack must not rest on the water heater.
6.
The vent must be easily removable from the top of the water heater for normal service and
inspection of the unit.
7.
The water heater vent must not be connected to any other gas appliance or vent stack.
8.
Avoid locating the water heater vent termination near any air intake devices. These fans
can pick up the exhaust flue products from the water heater and return them to the building.
This can create a health hazard.
9.
Avoid using an oversized vent pipe or using extremely long runs of the pipe.
10. Locate the vent termination so that it cannot be blocked by any debris, at any time. Most
codes require that the termination be at least 12 inches above grade, but the installer may
determine if it should be higher depending on the job site condition and applicable codes.
11. For rooftop venting, a rain cap must be installed.
12. The manufacturer recommends the NovaVent line. However, the following are also UL
listed manufacturers: ProTech Systems Inc. (FasNSeal), Metal-Fab Inc., and Heat-Fab Inc.
(Saf-TVent).
