I am not an expert. this is how i fixed my rinnai code 99. my rinnai 100 4f would run for few seconds then the red light would continue to flash. code 99 would come up.i took the unit out of service. i notice that the fresh air hose had two very small hoses located on it's elbow had been switched around when i took it to be serviced. the unit worked well. how ever. i changed my mind when i realized the service was not need. anyway the two small hoses on the elbow one office is larger than the other and they must be put on the correct one,i switched them around the unit flamed up. and now i have sweet heat again.no code 99.

SOURCE: Want to hook wall thermost to Rinnai propane space heater

If you are just going for heat only just connect the t_stat at these setting red wire R white wire to W green wire to G

Now the heater you can go to the gas valve or if it has a circuit board go to Red to R and white to W Green to G. Green is optional you just need two wires hooked up. You will see on top of the gas valve three connections the ones marked th are the ones you need.

SOURCE: 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...

SOURCE: flashing code 99

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.

What is the outside temperature? If it it is below freezing, you might have a frozen pipe. Using a plumber torch heat up the pipe, if it works, replace the insulation using a heavier layer.

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.

Converting Rinnai REH-25-N to LP


Typically, an unvented heater or gas log cannot be converted, mostly for safety reasons and it is usually cost prohibitive. Some newer heaters come with both Natural Gas and Propane components and have to be set up one way or the either.
It would be better to sell your old heater and get one with the proper gas type.

Rinnai Tankless Water Heater


Question, is there any other equipment that uses propane? You indicate that the problem started after a delivery of propane after running out. If so, I suspect a blockage in either the gas train or the rinnai itself. If tou have the temperature control that regulates the water temperature, you can recall error codes to pinpoint the issue. They are optional equipment so if you can wire one in or ask your propane gas supplier if their service department has one, it will aide in the diagnosis.
