The Rinnai gas automatic change over system guarantees a hot shower, even when running out of gas. The gas water heater will issue a blinking code error 12 when runs out of gas. The error code 12 is used to trigger the spare gas bottle. The person under the shower has to close the hot water tap and re-open, thus the gas water heater will re-ignite on the spare gas bottle.
