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 terminator 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 terminator is recommended when the Hydro-Smart 170 is vented
through a sidewall. If the Hydro-Smart 170 is converted to a direct-vent unit, a proper
sidewall direct-vent terminator is to be used.
General rules for venting the Hydro-Smart 170 are:
1.
Place the Hydro-Smart 170 as close as possible to the vent terminator.
2.
The vent collar of the Hydro-Smart 170 must be fastened directly to an unobstructed vent
pipe.
3.
Do not weld the vent pipe to the Hydro-Smart 170 collar.
4.
Do not cut the vent collar of the unit.
5.
The weight of the vent stack must not rest on the Hydro-Smart 170.
6.
The vent must be easily removable from the top of the Hydro-Smart 170 for normal service
and inspection of the unit.
7.
The Hydro-Smart 170 vent must not be connected to any other gas appliance or vent
stack.
8.
Avoid locating the Hydro-Smart 170 vent terminator near
any air intake devices
. These
fans can pick up the exhaust flue products from the Hydro-Smart 170 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 terminator so that it cannot be blocked by any debris, at any time. Most
codes require that the terminator 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.
