Adequate Drainage
This non-condensing water heater may produce
condensate within the vent system due to the
condition of the installation. Condensate can be
drained through the condensate collector. The water
heater should be located near a suitable drain and
where damage from a possible leak will be minimal.
Installing the water heater in a location
Note
without a drain will void the warranty
and Navien will not be responsible
for water damages that occur as a
result.
The water heater must be located in an area where
leakage of the unit or connections will not result in
damage to the area adjacent to the appliance or to
lower floors of the structure. When such locations
cannot be found, installation of an adequately
drained drain pan under the water heater is
highly recommended. When installing the drain
pan, ensure that the installation does not restrict
combustion air flow.
Navien will not be liable for any

damages caused by water leaks.

Installing the Water Heater
Adequate Venting and Ventilation
Select a location that requires minimal venting.
Consider venting restrictions caused by windows,
doors, air intakes, gas meters, foliage, and other
buildings. For more information about venting, refer
to "3.5 Venting the Water Heater (Indoor Models
Only)" on page 34.
WARNING
Improper venting of the water heater can result
in excessive levels of carbon monoxide, which
can lead to severe personal injury or death. This
water heater must be vented in accordance
with the "Venting of Equipment" section of
the latest edition of the ANSI Z223.1/NFPA
54 Natural Fuel Gas Code in the USA, as well
as all applicable local building codes and
regulations. Follow all instructions and guidelines
when venting the water heater. Venting should be
performed only by a qualified service agency.
To ensure adequate venting and ventilation, follow
these guidelines:
Maintain proper clearances from any openings in
●
the building.
Install the water heater with a minimum clearance
●
of 12 in (300 mm) above an exterior grade or as
required by local codes.
Do not enclose the vent termination.
●
Install the exhaust vent in an area that is free from
●
obstructions and does not allow the exhaust to
accumulate.
Do not install the water heater where moisture
●
from the exhaust may discolor or damage walls.
Avoid installing the water heater in bedrooms or
●
any other occupied rooms that are normally kept
closed or that are not adequately ventilated.
Install a carbon monoxide detector in
●
dwelling areas nearby the appliance. Refer
to manufacturer's instructions as well as the
Consumer Product Safety Commission (CPSC)
and Environmental Protection Agency (EPA)
recommendations for proper use of carbon
monoxide alarms.
