I think that's the room temperature setting you're looking at. H is high, 18 is 18C. See pg.11 of the linked manual.

Error Code 62, indicates a faulty fan motor. Which, according to your Owner's Manual, requires a service call by an authorized Rinnai service technician. it may not mean replacing the fan motor. It could also mean a faulty fan sensor.

Hope this helped you. Cheers.

Hi.

12 flashes means "Incomplete combustion". The code is prompted when the flame turns off because of a problem.

Check filter, check gas pressure and thermocoupling. Those are the problem that commonly trigger the code 12 error.

Here a manual.

Here Fixya thread on the problem.

I am assuming this is a tankless heater. Are you turning the water on full throttle and is there full flow. First thing to check is the small filter screen on the inlet of the water heater. If the flow is reduced the water heat will not fire.

I think you will find the thermocouple or thermostat has gone this allows the gas valve to open and is a saftey device to stop the escape of dangerous fumes .. it looks like a long piece of thin copper wire approx 4mm thick and it extends from the main valve into the pilot light flame .. When the ignition is pushed and you hold your finger on it for a while this tells the the valve that the pilot light is lit .. conduction of heat along this pipe then opperates the diaphram in the valve allowing the gas to the burners the pilot light then ignites them .. if the pilot light goes out the unit will nort run ..
My advice to you is that even though you may be conversant with the heater .. they do tend to have all manner of faults occur when left in storage or if shipped ( jostling and bumping ) is to get a trained gas engineer to check it out it may cost a bit .. but a gas escape and the following reprocussions are far more exspensive and costly .. Also You may not be aware that if you do have an incident your house ,insurance may be null and void if no service documents can be raised for the correct servicing of a fixed or mobile gas Convector .. I hope this helps Regards Vortash

62 - fan/motor appliance abnormal overheat

Check convection fan motor.
Get a gasfitter to do it.

Hi This is happening to us and I called Rinnai... they suggested that if anyone either in our apartment or an ajoining one has painted walls or varnished a floor that the convection heater picks up the smell and the only way to get rid of it is to burn it off by running the heater for several hours in a well ventalated room...

I am going to try it tomorrow.

will let you know

Hi, Here is the link to the manual. I think something like 'thermo coupling' probably means you need a technician!

I believe the 12 is the error code for "incomplete combustion". In this case you will want to start with the thermocouple. If you are not handy at these things I would call a service tech. You can find a service person on their website.
