SOURCE: Rinnai fan stops turning.

You can reach the fan wheel by using a can of compressed air normally used to clean your compute keyboard. Make sure you hold a vacuum wand close to the heater when doing this to collect the debris. Using a small coffee stir straw, lubricate the end of the fan motor shaft with light motor oil. This will keep the motor alive for a bit longer.

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

Is there any possibility my Rinnai econoheat850 gas heater can give off carbon monoxide?


Any time there is combustion of any type fuel, from a Rinnai heater to a car engine. There is always a small amount of Carbon Monoxide given off. But, it's usually in small insignificant amounts.

Since your model is a Vent-free or flue-less model, the chances are a little higher. This usually occurs if the heater has not been properly and regularly maintained. Keep in mind, flue-less heaters take in household air for combustion, heat it and send it back out. Whatever is floating in the household air (duct, lint, pet hair, etc) is pulled into the heater. These things can clog the burner(s), the pilot and the Oxygen Depletion Sensor (ODS) and cause incomplete combustion. Which translates into higher than normal Co levels. However, your unit is equipped with an ODS, that will shut the gas off to the heater, if the household oxygen level reaches 25%. Which is not the danger level, which is 19%. Once the Oxygen level returns to 30%, the ODS will release the gas valve and gas will return to the pilot, so that you can relight it.

When properly maintained and operated according to the Owners Manual (see link below) they are totally safe. In the last 20 years, millions of vent-free/flue-less heaters have been sold and operated throughout the world. There has never been a death related to their use.

Certainly, if you or your family think you are experiencing signs of carbon monoxide poisoning, stop using the heater and have a qualified Rinnai technician check and service the heater. If you have other gas appliances in the house, it may be one of them causing the symptoms and not the heater. You may want to have those check and serviced, too.

I have a yamaha tdm 850 1992 model, it runs and startds fine and does not miss a beat. over the last day it has started to cut out completely at freeway speeds. it will do approximately 10 minutes fine...


Because of the higher voltages run in bikes nowdays to meet fuel regulations,spark plugs are often a big problem.Drop a new set of plugs in .It's the easiest and cheapest place to start.No dealers to rip you off.If this is not the problem,it would suprise me.Hope this helps

Hi there, I have a rinnai 20 ,the water heats up


Usually this type of fault is down to poor water flow. Basically you are asking the unit to work at a level below it's minimum output. Easy thing to try is to check any filters or water flow limiters in your tapware. Usually these are in the nozzle of the tap. I often take these out. The inifinty reduces water flow anyway and there is no reason to have water limiters. Try turning on two taps at once. If this stops the fault then you definately need to increase your water flow. Make sure the mains water is turned on full. Aslo you can check the cold water filter on the infinity. It's just above the cold water isolation tap (middle pipe as you look at it), turn that off first, the filter is a round plastic nut, unscreww it and clean the filter. Reconnect, turn you mains water back on.
There are other faults but this is by far the most common.

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.
