Dishwasher / hot water heater / hydrogen gas risk.

We just bought a new dishwasher (General Electric (GE) model number GSD5620). Listen to something that was near the beginning of the instruction manual :

********************

WATER HEATER SAFETY.

Under certain conditions hydrogen gas may be produced in a water heater that has not been used for two weeks or more. HYDROGEN GAS IS EXPLOSIVE.

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 faucets and allow them to run for several minutes. Do this before using any electrical appliance which is connected to the hot water system. This simple procedure will allow any built-up hydrogen gas to escape. Since the gas is flammable, do not smoke or use an open flame or appliance during the process.

***********************

What ? Huh ?

Anyone know if this is only an issue with either electricity or natural gas powered hot water heaters ?

Or, is this an electrolysis of water type thing ?

Jon.
