Error code 99 has to do with the flue pipe being blocked. You could have ice or frost on the exhaust or air intake. This reduces the combustion air to the unit which in turn stops the fuel flow.

Bad pressure switch or a bad sparker board.

    Sorry to disagree but Page 12 of the installation manual clearly indicates otherwise.

Rinnai ex 38 flashing code 99. I took the vent apart and there is no blockage. Unit has only been installed one month.


If it is only one month old doesn't do anything but call for warranty serving. ANY attempt to repair this will void the warranty.

I HAVE A JACUZZI HEATER RINNAI 95GS-5 DO THINK PROPANE WOULD WORK ON THIS ITEM


Contact Rinnai, or look at product manual.
Products rated for natural gas do not work with propane.
Propane burns hotter and has more pressure... wrong gas can cause explosion

My Rinnai 1004F giving me error code 99


This fusible link may be open. Try jumpering the two leads and see if the unit operates. If it does replace the fusible link. Do not operate the unit without the fusible link for an extended period. It is a safety device and is there for a reason. Hope this helps.

Problem is with my Rinnai propane gas heater in my LIVING ROOM, not car. Please see previous question. Thanks.


Turn it off. Check connections and hoses with very soapy water for leaks (it will bubble)

If you can't find it... I would either return it if possible... or go take it to a propane professional for testing.

I have a Rinnai 556F Heater and I set it to a specific Temperature and a temperature higher is always flashing. What is wrong?


The temp you are looking at may be an error code. 72 Room sensor, 68 Over heat, 76.80 Room sensor short, etc. What is the exact code??

Rinaai LP space heater will not shut off when set temp is reached


Test the thermistor by using an ice cube. Place the cube on the thermistor and see if the unit starts. Then using a warm towel, wrap the thermistor ans see if it stops. Watch the display to see if it is registering the changes in temp. I suspect a bad thermistor.

My rinnai 556fa propane heater


I had the identical trouble with my Rinnai 431F just now & read the unanswered posts.

I checked my intake & exhaust & found them connected & intact then went out to check the exterior vent assembly. The "bell" or dome was almost entirely clogged with ice.

I suspect the 60 - 76 lights flashing means insufficient combustion air.

Anyway, I took a hair dryer to it & in 10 minutes it was working as well as ever.

This won't help you October posters but if anyone else has this problem in the future I would start with the outside vent assembly. Get a good look right up inside because I would have missed this ice if I didn't get up close with a flashlight.

Here's a good source for manuals too...
