This error is a Flame failure alarm.

It would be good to click HERE and print off all the alarm codes to keep.

As you've just put new gas on, you will probably have to purge the system of air before you get any gas through.
You can probably do this at the heater end.

You first need to check you are getting a spark to the pilot.
If not, check electrical connections, and trace fault to the ignition assembly.

If you are getting a pilot flame (unlikely as you're getting an alarm), you will need to concentrate on the hot-wire sensor and check if it is faulty.

Thanks for using Fixya. Please rate if this works for you.

Calling for heat red light flashing 2times

Hi, pull the panel off the unit where the light is flashing. If everything stops working, then you have a switch around the perimeter of the panel that killed the power and you will need to tape it down to restore power to the furnace. Once this is done, ( if it even happened ) look on the panel or the unit for a strip of paper that will be glued there telling you what each code means, and what to do to solve the problem. 2, 3, 4567 flashes mean different things going on. It may have tripped a limit switch, flame roll out switch ect. These are manual reset switches, so you will have no problem resetting them. I hope this was of help to you.

OUr Rinnai gas heater convector 516tr keeps on turning itself off and flashes 12 on the light panel. What does that mean and how to fix it? tks


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 installed a control board in my furnace now light keep flashing

Hi, You need to remove the panel that was covering the circuit board to find the chart that is glued to it. This is the error chart and will lead you to the problem by the amount and how many times the led flashes. For instance, a steady flash, 4 long and 3 slow, the chart will tell you like 43 or 4-3 to go there and will tell you what is taking place. This will almost do the trouble shooting by it self. Get back to me if you need more help. Look for this chart as they all have one.

Can not figure out how to control thermostat

If you take off the front control panel cover (simply prying off on the edge with finger) you will find 2 small buttons under the display panel, one being mode and the other being prog.

Press both simultaneously and hold down for 5 secs and the display will blink, press prog to advance to what you want to program, kinda like setting a timex watch. As I recall you can set degrees celcius or farenhight/ cycle/Hi/Lo etc.

Just keep in mind when you set using the up and down arrows:

flashing H means: at what temp do you want HEAT to kick in?

flashing C means: at what temp do you want AC (if you have it) to kick in....if no A/C fan simply blows air.

Hope that helps.
