The heater is rated Category IV (pressurized vent, likely to form
condensate in the vent) and requires a special vent system designed
for pressurized venting.
NOTE: The venting option described here (and further detailed
in the Venting section, this manual) is the lone venting option
approved for this water heater. Failure to install the water
heater in accordance with the provided venting instructions will
void the warranty.
The exhaust discharged by this water heater may be very hot.
Avoid touching or other direct contact with the exhaust gases of
the vent termination assembly. Doing so could result in severe
personal injury or death.
Do not attempt to vent this water heater by any means other than
those described in this manual. Doing so will void the warranty
and may result in severe personal injury or death.
Failure to vent the water heater properly will result in serious

Outdoor Installation
This water heater is designed to draw combustion air through the
louver system in the heater cabinet. This combustion air also serves
to cool the internal electronics when the heater is installed in very
warm climates.
To prevent combustion air contamination or exhaust recirculation:
• Flue gas can cause damage to exterior walls and other
devices.
• Locate the heater at least 48” below or horizontally from any
window, door, walkway, or gravity air intake.
• Locate the heater 10’ away from any public area, outdoor
sitting area, or forced air inlet.
• Locate the heater away from areas that may change over
time. Do not allow the growth of trees, shrubs, or plants to
obstruct proper operation of the exhaust vent system.
• If the heater is located in a fenced area, ensure the unit
exhaust vent extends level with or above the top of
the fence to ensure flue gas does not get trapped and
possible recirculated into the louver system, which could
contaminate combustion air.
See Venting section for additional details.
