Question about Heating & Cooling
Hi. I have a Rinnai Timberflame Centrum gas fire. It is constantly cutting out with the number 12 flashing in the screen. I can not find my manual nor can I find one online. Could you please tell me what code 12 means and if possible where I can get a manual online. Many thanks, Tracy

SOURCE: my rinnai gas log fire
Fault code 12 means the flame lit ok but hen for some reason went out. In my experience this usually means a fault on the gas supply itself. If you are on lpg I have had many problems with gas regulators recently. If you have something else on gas like a cooktop, fire that up first, then try the log fire. If this seems to fix the fault get a gas fitter to change the regulator.
Make sure all taps and isolattion valves are fully on.
I'm have assumed this is not a new installation so the unit has worked ok before.
Does the flame stay strong after it lights. If it slowly fades then definately a gas supply problem.
If it stays strong but just shuts of with a click, then possibly a fault on the heater, check the rod the flame heats is well in the flame. Could be the electronic otherwise but very rare.
If the flame goes yellow like a candle and then shuts off you will need to check the flue or chimmney as this might be blocked..
Cheers, let me know if anything works and re-post with any more info if you are still stuck, I will keep a look out for you.

I had this same problem last year and went through all the checklist in poshpoms suggestions ( I am on mains Gas ). The issue was caused by the Flame rods. Near the 2 pilots at the front and the back. Those small rods each that 'senses' the flame become inadequate, so they were replaced with a new pilot assembly from Rinnai that had longer rods and better coverage. Issue was fixed. Good Luck.
