4 Getting Started
4.1 Location
WARNING
Fire, explosion!
• Areas where ammable liquids (gasoline, solvents, liquid propane,
butane, etc.), or other substances which emit ammable vapors are
stored may not be suitable for water heater installation. Natural air
movements can carry ammable vapors varied distances from where
they are stored or used. The water heater thermostat contacts can arc
and ignite these vapors causing property damage, serious burns or
death. Never store or use ammable substances in the same room or
area containing an electric water heater. Gasoline or other ammable
substances must never be used in the same room or area containing a
water heater or other spark-producing device.
WARNING
Personal injury, product damage, property damage!
• Indoor installation only. Do not install outside. Failure to follow this
warning could result in property damage, severe personal injury, or death.
Local codes and requirements in your area may require that the water heater be
installed in such way that the bottom heating element is elevated at least 18 inches
from the floor.
This residential water heater should be installed in a clean, dry location with an
ambient temperature always above freezing and close to where a good electrical
connection can be made. The unit should be as close as possible to major usages of
hot water. The unit can be installed on a combustible floor with 0 inches minimum
clearance between the rear of the water heater and combustible walls. The water
heater should be located so that all electrical controls, air filter, heating elements,
drain valve and water connections are accessible. For easy servicing the anode rod
increased top clearance is recommended. Refer to table 4 for required clearance
for operation and maintenance.
If the unit is installed in an enclosed room and not fully ducted, a space of 700 ft³
(19.8 m3) is required to provide enough airflow. Insufficient space will cause
higher power consumption. Check space requirements below in chapter 5.2.
To have maximum efficiency, install in an area that remains in temperature range
between 37 °F (3 °C) and 109 °F (43 °C) to ensure operation of heat pump.
In normal conditions the water heater operates below 49dB(A), which is
comparable to a quiet refrigerator, but keep this in mind when choosing a location.
Required Clearance for Operation Required Clearance for Service
Air Exhaust 6" (15.3 cm) 6" (15.3 cm)
Top 20" (51 cm)
50 Gallon: 25.5" (65 cm)
80 Gallon: 32" (81.3 cm)
Table 4 Required minimum clearances
4.2 Air Flow Requirements
This water heater uses the heat in the air to heat up the water in the tank. Therefore
a minimum enclosed space of 700 ft³ is required to ensure desired operation. Not
enough air flow may result in increased usage of the electric heating elements and
therefore reduction of efficiency and increased power usage.
If installation place is smaller than 700 ft³, consider louvered door options to
the space or ducting the air flow to and from the unit. Refer to the options shown
below.
