Error Codes - Rinnai Novo Operation Manual

Error codes

The Novo has self diagnostic electronics that monitor the appliance during start up and operation.
Should a fault occur the heater will shut down. The fault that has caused the shut down will be
indicated by a pair of flashing numbers in the error display. The error will show through two narrow
cutouts—you will need to walk up to the fire and look down to see these.
