An H12 indicates a flame failure, which could be caused by an obstruction in the combustion chamber, buildup of debris on the flame rod, not enough or no fuel, or no spark at the igniter. You may wish to get a technician in and look at these. One thing I have found is that spiders love to webs in the burners of these heaters and the only way to check it out is to disassemble the entire burner.

How to install


Unfortunately, the installation of one of these units is not quite as simple as 1, 2, 3.

So, I am providing a couple links on the installation process. You can download and print each one.

The first is the Flue Installation Guide.
http://www.rinnai.com.au/images/stories/operating_instructions/Heating/Energysaver/CI_ES_Flue_Inst_Manual.pdf

The second is the Operation Guide, which also deals with proper installation.
http://www.rinnai.com.au/images/stories/operating_instructions/Heating/Energysaver/CI_ES_Flue_Inst_Manual.pdf

The third is the exploded parts view & parts diagram, Which you may need in the future.
http://www.rinnai.com.au/images/stories/operating_instructions/Heating/Energysaver/CI_ES_Flue_Inst_Manual.pdf

I hope all of this information will help you properly install the unit.

My tank says I have 32 gallons left but the heater won't work (rinnai 556f). It turns on for about 15 seconds and the light on the power button turns red and starts blinking. What does this mean?


If you hold down the economy button and the up and down arrow buttons for 5 seconds the unit will start an error code display. Get a helper and yell out the numbers when they start blinking. Post the error codes and we can help you
