Behind the unit near the floor level, is a yellow wire with a black bulb at the end. This is the actual sensor for returning air. If there is cool air infiltrating the area where it is located, it will keep the unit running until the return air reaches temperature. You could also have a bad sensor but highly unlikely. Make sure there is no air infiltration influencing the sensor. Also, you can unclip the sensor and pull out a few more inches of wire to locate it higher up away from the floor. Tie it up with a wire tie.

Rinnai it testing a remote thermostat but as of yet, there is no plans to offer one.

Without a pilot flame sensor signal the pilot light will not stay on and the heater won't work. Try Replacing the pilot flame sensor, the pilot flame burns on to it and it connects to the valve. It looks like a wire.

A code 11 also means that it might not be getting any gas. On thr right side of the unit you will find a small door. open it up and make sure the valve is in the open position. If it is, you should contact your gas company to come and diagnose what is going on. The Rinnai is not a do it yourself fix it type of heater.

At the end of the document, notice there is a 10 pro rata warranty on the heat exchanger. The fact that they would offer you any money at all on a failure nine years into domestic use suggests they consider that part rather dependable. I have no access to Mean Times Between Failures on equipment. Such documents vary in calculations as what is considered a critical failure must be defined.

First thing to try is to check the flue to see if it is blocked or even partially blocked. This type of flue assembly exhausts burnt gases from the heater and another section draws fresh air in to the heater to be mixed and burnt with the gas.
the centre of the flue is the exhaust section and the outer section of the flue is the fresh air intake section.
removing the flue cowl will allow a visual inspection of the flue for any blockages.
If the flue is a long run then a plumber may need to be called to disassemble the flue for a closer inspection.

According to the owners manual, the "Economy" mode is designed to reduce the temperature setting by 2 degrees every hour. May not be what you were expecting... On the too hot issue: Check the thermostat setting - it can read either Celsius or Farenheit - Make sure you are setting it to what you think you are... Recommendation: if it is heating higher than set temperature is 1) set the temp lower and see how it does or 2) call a repair man to check and calibrate the thermostat.

Hi Doug,
I have not seen this problem and my suggestion would be to look at the bearings in the combustion fan motor.
This motor is located in the lower right hand side of the unit and can be seen once the front cover is removed.
You can watch and listen when the unit starts up from a cold start and this should confirm where the noise is coming from.
This part is not easily removed and I suggest an experienced service person should perform the removal and replacement if this part is causing the noise issue.
if this does not help please contact me again
Good luck

On miscellaneous heaters gas(some oil fired heaters) have what is called a spill out switch---this is located where--- if the stack is plugged the heat/flue gases will spill out and melt a heat sensitive switch causing it to shut the system down---- if this has happened you---you have to replace this in order for the heater to function---these sensors/switches are connected in series for safety to eliminate carbon monoxide poisoning----de>th----fire
