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.
Hi there, i have same unit and its got error 70 coming up. Which is faulty on off switch as per manual. I can confirm on off button on control panel, up on top is not working however remote is working. When i try to start it with remote it comes up but turns itself off with error 70 again. I tried to remove this control panel (pcb) from unit however it is still doing same. Now i am not sure if it is actually pcb panel which is faulty ? Please help ;)
Error Code 62, indicates a faulty fan motor. Which, according to your Owner's Manual, requires a service call by an authorized Rinnai service technician. it may not mean replacing the fan motor. It could also mean a faulty fan sensor.
Since, your Rinnai Heater is Vent-free, it can not be converted to a Vented Unit. The design does not allow it. Even if you could, the efficiency rating would drop tremendously. Not sure that you'd want to do that, with the price of gas being what it is, now.
how far is the tankless from the gas meter? error code 12 means it doesn't have enough gas running to it. is the 3/4 flex true 3/4 or is it 1/2 with 3/4 threads. have you checked your BTU load on your house to make sure your 1'' pipe can handle everything else you have on the house? sounds like to me you dont have the right amount of gas to the unit.
I may not be much help here in the states but if you have the owners manual you will find a page that will tell you what the error code represents. Not knowing and unable to find the NZ error codes, most likely it represents a flame failure. You will need to remove the front cover and inspect the flame as it starts. If it starts and goes out quickly, you may have debris attached to the flame rod not allowing it to get the proper signal. Or you may have a spider web in your burner. These units are not eazy to repair and I strongly suggest you call a proffessional. Sorry.
gday nelson. if you check out the specs on the rinnai range you will find another one that will go straight in. if you buy new it will come with a new flue kit. as far as recomended installation heights most of them are quite flexible. i installed a second hand 403ft yesterday with the centre of the flue at 140mm from the floor. recomended in the instructions were 240mm. a mate gave me the heater and i just had to buy a flue kit as the old one was already too short. if you messure your flue from inside and send me the specs i can give you a more difinitive answer.
This is a New Zealand model. There is no pilot to relight, the unit will cycle again when you stop and restart the unit. You will need to find out why you are getting this code. I would check out the venting system for blockage. Make sure you are getting gas. You may want to take off the front panel and look into two small rectangular holes covered by small metal plates to see if, in fact the flame is starting then stopping. I have seen many of these with spider webs inside the gas train and burners not allowing the heater to start. If you can get to the backside of the heater, you will see a rubber hose about 1" (US) in diameter. Remove it from the vent and see if the unit ignites. If it does, this indicates blockage in the outer vent passage. If not, you may need to contact a technician to investigate your issue.
