Rinnai Continuous Flow Water Heaters Operation Manual page 12

General controller information
Controllers need to be turned on for delivery of hot water
The water heater will not heat water unless the controller(s) are turned on. If water is flowing
before a controller is turned on, the water heater will not heat the water. Turn off the tap for a
few seconds then turn on again.
Ignition problems
If the water heater fails to ignite, the 'In Use' indicator will not illuminate. The water heater will
not attempt re-ignition until water flow is stopped for a few seconds and then re-started.
When gas bottles have been changed or the gas supply is disrupted (controller may display
error code 11 or 12) ignition may fail and the 'In Use' indicator won't be on. The water flow
may need to be stopped and re-started several times before the appliance will remain alight.
