Question about Rinnai Heating & Cooling
I just bought a 2nd hand Rinnai Econoheat 850 gas heater.
When I press the control button down, the ignition works fine and burners come on (gas supply present) and start turning bright. But when I release it after holding for 10 seconds, the burner goes off. I have tried ventilating the room, replacing the battery and also holding the button down longer (30 sec, 1 mn, even 3 mins) but these don't help. Can someone please help?
The thermocouple [s] require replacement, or in my experience try servicing the unit first. There is an injector for the main pilot and a secondary injector for the flame thrower ignition. Both of these are prone to blocking due to dust and can be enough to shut the unit down. Although usually this is thermocouple related as you are manually keeping the unit running when you hold down the button, if the tcouple is broken it wont send enough millivolts to hold the magnetic valve open when you release the button.

Firstly I suggest blowing out the burners with compressed air to see if that makes a difference. Could be the burners are carboned up and just need cleaning. Also blow through the air hose with the igniter button down. Sometimes if the heater has sat for a while in or near a damp area the hose gets moisture in it and it will stop the burners also.
If this doesn't work then it would seem that the sensor beside the igniter is probably stuffed and will need replacing. This sensor is a fluid type sensor and when they burst or get a hole in them it stops the candles burning.
Hope this helps
