Vent Pipe Installation (When supplying combustion air from the indoors (SV, non-direct vent))
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" configuration (using an SV conversion kit) is prohibited.
indoors as illustrated to the right. Refer to page 31 for the location of the dip switch bank.
SV Conversion kit #SV-CK-3 is required for the air intake. The SV Conversion Kit
#SV-CK-3 is contained within both the Horizontal Installation Kit (TWHHORKIT)
and the Vertical Installation Kit (TWHVERTKIT).

Terminate at least 3' (0.9m) above any forced air inlet within
10' (3m) , 4' (1.2m) below, 4' (1.2m) horizontally from or
1' (0.3m) above any door, window, or gravity air inlet into any
building per National Fuel Gas Code ANSI Z223.1/NFPA 54.
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 installation
instructions.
The TWHVERTCAP termination may be used
in place of elbows as the vertical vent termination.
Terminate at least 6' (1.8m) from the combustion air
intake of any appliance, and 3' (0.9m) from any other
building opening, gas utility meter, service regulator etc.
Enclose exterior vent systems below the roof line to limit
condensation and protect against mechanical failure.
When the vent penetrates a oor or ceiling and is not
running in a re rated shaft, a restop 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.
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.
* Dip switch No.3 is turned on.
