WARNING
If the water heater display does not show “Operational” in the “Status” indicator, there may be an operating
malfunction with the water heater. If this is the case, a numeric code will be displayed. Refer to the label
next to the display for the definition of the error code and call your plumbing professional or service agent to
service the water heater.
DO NOT
try to reset the water heater without having a qualified service person
attempt to diagnose and correct the problem. If the display is blank or does not show an error code, make
sure there is power to the water heater.
Setting the water temperature to the maximum set point can result in scalding hot water delivered to the
faucets. It is highly recommended that the maximum setpoint be adjusted to the lowest temperature possible
for the needs of the installation. See the following section to change the maximum setpoint limit (max
setpoint). Make sure the water heater control display is not in a public area that can result in the
temperature settings being improperly adjusted. See previous warning on scalds and an ASSE approved
mixing valve.
NOTICE
When the maximum setpoint is reached, the display will show “Max Setpoint” without the setpoint value. The
maximum setting is equal to approximately 180˚F
(82˚C)
. The default temperature setpoint from the factory
is 10
0˚F
(38
˚C)
.

WARNING
Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for
a long period of time (generally two weeks or more).
HYDROGEN GAS IS EXTREMELY FLAMMABLE
. To
prevent the possibility of injury under these conditions, we recommend a hot water faucet to be open for
several minutes before you use any electrical appliance which is connected to the hot water system. If
hydrogen is present, there will be an unusual sound such as air escaping through the pipes as hot water
begins to flow.
DO NOT
smoke or have open flame near the faucet at the time it is open.
