INSTALLATION
Opera on
The water heater is now ready for
normal opera on. To keep your water
heater working safely and effi ciently
and extend its life, perform mainte-
nance according to the schedule on
page 29.
Turn the electric power on at the
circuit breaker panel, or fuse box.
Power to the water heater will allow
the water heater to run a system
diagnos c. This typically takes eight
minutes. Once complete proceed to
the next step. NOTE: If the system
diagnos c yields any codes, reference
the diagnos c codes sec on in this
manual. Adjust the thermostat to the
desired temperature se ng, and the
opera ng mode, as described under
“Adjus ng the User Interface Module
/ Opera onal Modes” sec on.
Vaca on Mode (ESM)
To save energy, lower the tempera-
ture se ng on the thermostat if you
plan to be gone for an extended  me.
Follow the instruc ons in Step 10 for
adjus ng the thermostat to a lower
temperature se ng before you leave
and to properly raise the temperature
se ng when you return (See page 17
for ESM Mode Descrip ons).
Step 11:
C AUTION! Hydrogen gas builds up
in a hot water system when it is not
used for a long period (two weeks
or more). Hydrogen gas is extremely
fl ammable. If the hot water system
has not been used for two weeks or
more, open a hot water faucet for
several minutes at the kitchen sink
before using any electrical appliances
connected to the hot water system.
Do not smoke or have an open fl ame
or other igni on source near the fau-
cet while it is open.
