Important Safety Information
Read all safety information before using
Under certain conditions
hydrogen gas may be produced
in a water heater that has not
been used for two weeks or more.
HYDROGEN GAS CAN BE
EXPLOSIVE UNDER THESE
CIRCUMSTANCES.
SAVE THESE INSTRUCTIONS
If the hot water has not been used
for two weeks or more, prevent
the possibility of damage or injury
by turning on all hot water taps
and allow them to run for several
minutes before using any
electrical appliance which is
connected to the hot water
system. This will allow any
hydrogen gas to escape. Since the
gas is flammable, do not smoke or
use an open flame or appliance
during this process.
