18 Installing the Water Heater
3.2 Mounting the Water Heater to
the Wall
Navien water heaters come with two upper and
lower mounting brackets that are pre-drilled at 16
in for easy installation on standard wall studs. If the
strength of the wall is insufficient or if the framing
is non-standard or uneven, reinforce the area
before installing the water heater. Avoid installation
on common walls as the unit will make some
operational noises while it is running.
WARNING
●
If the water heater is not properly and
securely attached to the wall, it could become
dislodged causing the exhaust vent pipe to
separate. This can result in carbon monoxide
emissions which could cause severe personal
injury or death.
●
Be careful not to drop the water heater while
lifting or handling it to avoid bodily injury or
damage to the unit.
●
Do not
rest the water heater on the bottom
end after removing it from the shipping
carton. Doing so may result in excessive
pressure on protruding pipes and cause
product damage. If you must put the water
heater down, lay it on its back or put it inside
the protective shipping base.
●
Install the water heater upright in the vertical
position. Installation in any other orientation
will result in improper water heater operation
and property damage, and could result in
serious personal injury or death.
CAUTION
●
Ensure that the structure of the installation
location is sturdy enough to support the full
installed weight of the water heater, including
water content of the heat exchanger and
related piping.
●
The wall must be vertical, and it must be
capable of carrying the weight of the water
heater.
●
Do not mount the water heater to dry wall
that has not been reinforced.
High Elevation Installations
This water heater may be installed at elevations up
to 10,100 ft (3,078 m) for use with Natural Gas and
Propane. Refer to “3.7.2 Setting the Front Panel DIP
Switches” on page 44 for the appropriate altitude
setting.
Coastal Installations
For installations in sea or marine environments, the
salty air can cause corrosion to the water heater. The
water should be protected and enclosed to minimize
exposure to the corrosive atmosphere. Damage due
to a corrosive environment is not covered under
warranty.
Operating Temperature
The ambient temperature at the installation location
must be above freezing temperature and below
120˚F (49˚C).
