INSTALLATION
Step 11:
Operation
The water heater is now ready for
normal operation. To keep your
water heater working safely and
efficiently and extend its life, perform
maintenance according to the
schedule on page 24.
Vacation
To save energy, lower the temperature
setting on the thermostat(s) if you
plan to be gone for an extended time.
Follow the instructions in Step 10 for
adjusting the thermostat to a lower
temperature setting before you leave
and to properly raise the temperature
setting when you return.
CAUTION! 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
flammable. 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 flame
or other ignition source near the
faucet while it is open.
