SOURCE: Rinnai Econoheat 850 gas heater

Hi Daryl,

It needs a service. The jets carbon up and when they heat up they stop the gas getting through. If you take it to a Gas Shop they will charge you around 90-00 to service it and all they will do is blow it out with compressed air. If you can get hold of an Air Compressor with an Air Blower on the end you can blow it out yourself. Remove the Gas Hose from the back and place the Air Blower into the hole where the gas goes through and hold down the ignitor switch to open up the jets. Give it a good blow out. Once you have done that give the candles a blow as they eget dirty also. You will see a white dust more than likely come out of them. If you want to give it a good clean out remove the cowling and clean (blow out) the inside of the Heater. The cowling from memory has only about 6 or 8 screws holding it on. That should take the top and sides off. I can't remember if you can remove the lower vent on that model - if so it will only be either 2 or 4 screws. Hope this Helps.

Regards
Bryan

Hi there,

sounds like it has a faulty button. The "on" button on that model has a button on the front side which should hold the on button down after igniting. Check and make sure that it is there. I think it is a spring loaded button - maybe the spring has dis-lodged itself. If the button is faulty yhou can only replace it.

Hope this Helps

SOURCE: Rinnai burner goes out when ignition button is released

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.
Cheers

SOURCE: What causes a diffrence in glow colour?

Normally purple/blue on the radiants indicates low gas pressure, could also be dust slowing gas velocity into burner and/or an aeration problem. Get it checked out properly.

The electronic ignition does not work. I have check all plugs. It does not make a click noise, no spark or power.


You didn't say whether it is a piezo-electric spark generator or whether it is battery-driven?

Piezo-electric is usually fairly reliable in operation but has gone out of fashion somewhat because it generates only one spark at a time which often does not provide reliable ignition.

Battery driven ignition systems provide a much more reliable ignition as they produce many really good sparks. The ones I have encountered operate from a single 1.5 volt battery which is adequate for the task as long as there are no poor connections and a good current supply is available to the spark generator.
Unfortunately the cooking environment is not conducive to keeping things clean and grease can penetrate the push-button, the battery compartment and connections and grease and carbon can impregnate the insulators causing a short-circuit.

Mostly in my experience these ignitions work great when new but soon lose efficiency and stop working. The one on our cooker soon became almost a hobby needing fiddling around with so often before it would work that we now use matches. The cooker before last also had the same story...
