Rinnai 560PTR Heater Converted Propane To Natural Gas No Ingition

I have a Rinnai 560PTR Heater that I had converted to Propane Gas from Natural Gas by a Licensed Plumber. He left my us the Natural Gas convertor so if we moved back to our old area we could get it converted back to Natural Gas. My husband downloaded a detailed manual on how to convert this Heater back to Natural Gas and did this but it is now showing with:

Error Code 11 or 12

Which is not be able to Ingite the heater we have checked everything but can not get this to Ingite it clicks for about 15 seconds but then either shows Error Code 11 or 12.

Can anyone help us with this problem please.

It would be just wonderful if you could....

    Thank you so very much. I have booked a Plumber to arrive at my Home on Monday Morning - I was very worry in the first place to even try this home convertion.

    We hope you have a wonderful Weekend.

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

    And to you I am so relieved you have someone coming in but may I add in this country a gas fitter has to be corgi registered this is a professional body that governs the rules and regulations as to who can fit and repair gas appliances I don't know if you have this in the states .. anyone here can become a plumber with a bag of tools and a spanner .. who don't mind putting his hands down toilets ... eeeeewwww not my thing lol .. but you have to be trained to be a gas fitter repair engineer .. in other words make sure he knows what he is doing and if you have got a system like that in the states make sure he is registered after all it is your life ?.... Regards Vortash have a great weekend

Error 12 is generally a bad earth, dirty (carbon, rust etc) flame rod, or not enough gas.
Error 11 means failed to ignite, normally no gas, or not eough gas, or wrong type of gas.

Since it's a Rinnai Vent-Free LP Gas Heater .. No, it can not be converted to Natural Gas. No Vent-free Gas Heating Appliance can be converted from one gas type to another. It's not just Rinnai.

Converting Rinnai REH-25-N to LP

Typically, an unvented heater or gas log cannot be converted, mostly for safety reasons and it is usually cost prohibitive. Some newer heaters come with both Natural Gas and Propane components and have to be set up one way or the either.
It would be better to sell your old heater and get one with the proper gas type.
