In all cases, you may be able to clear the Error Message simply by turning the heater OFF, then ON again.

If the Error Message still remains or returns on the next operation, contact Rinnai or your nearest service

agent and arrange for a service call.

The Energysaver 1004 has the ability to check its own operation continuously.  If a fault occurs, an Error Message
will flash on the Digital Display of the control panel.  This assists with diagnosing the fault, and may enable you to
overcome a problem without a service call.  Please quote the code  displayed when inquiring about service.
