A tee, the PVT-HL termination may be used for the vent
termination. It is not necessary to use bird screens with
the PVT-HL termination.
Terminate at least 12" (300mm) above grade or above
snow line.
Slope the horizontal vent 1/4" upwards for every 12" (300mm)
toward the termination.
Use a condensation drain if necessary.
In the Commonwealth of Massachusetts a carbon monoxide
detector is required for all side wall horizontally vented gas
fuel equipment.
Please refer to Technical Bulletin TB 010606 for full installatio
n
in structions.
Enclose exterior vent systems below the roof line to limit
condensation and protect against mechanical failure.
When the vent penetrates a floor or ceiling and is not
running in a fire rated shaft, a firestop and support is
required.
When the vent termination is located not less than
8' (2.4m) from a vertical wall or similar obstruction,
terminate above the roof at least 2' (0.6m), but not
more than 6' (1.87m), in accordance with the National
Fuel Gas Code ANSI Z223.1/NFPA 54 or Natural Gas and
Propane Installation Code CSA B149.1.
Provide vertical support every 3' (0.9m) or as required
by the vent pipe manufacturer's instructions.
A short horizontal section is recommended to prevent
debris from falling into the water heater.
When using a horizontal section, slope the horizontal
vent 1/4” upwards for every 12” (300mm) toward the
termination to drain condensate.

Vent Pipe Installation (When supplying combustion air from the indoors (SV, non-direct vent))
• Disconnect power and turn ON dip switch 3 if combustion air will be supplied from the
indoors as illustrated to the right. Refer to page 34 for the location of the dip switch bank.
• SV Conversion kit #SV-CK-3 is required for the air intake.
* Dip switch No.3 is turned on.
Failure to perform the above 2 steps could result in a re or explosion causing
property damage, personal injury or death.
Refer to the instructions provided with the conversion kit for additional details.
WARNING
When installing this water heater in an area with a large amount of lint such as a commercial Laundromat,
direct -vent ("-DV") system must be used. The "-SV" conguration (using an SV conversion kit) is prohibited.
When installing this water heater in a mobile home, all combustion must be drawn directly from the
outdoors. The "-SV" conguration (using SV conversion kit) is prohibited.
