That unit has a 5 year warranty on the parts that you are talking about. The unit also is proprietary and you have to contact them for service.

I have a old Rinnai gas water heater Mod REU 55 FTB, after a year not in used, now the gas can not flow, how is the solution ? Thx


If it hasn't been in use for a year or so there could be a couple problems. Sometimes the gas dissipates from the line after an extended period of inactivity. You may need to try several times to light the pilot or the line may need to be purged. Also, if there's gas to the appliance and the pilot will light but not stay on the thermocouple is bad and should be replaced.

I have a Rinnai REU 55ft, which ignites but won't stay lit. We've cleaned the filters, fiddled with the dials and ensured that the batteries and propane are good. Any thoughts?


Hello,
In these water heaters there is a part called a "flame sensor", if you can read the wiring diagram/schematic spend some time trying to find where it is at; it will be located directly in the burner compartment. It senses that the gas is lit and there is flame, if it does not then it will shut the gas off almost within 3 seconds.
Solution- Turn off the power to the unit completely and take the flame sensor out and clean it with a 000 steel wool pad. These flame sensors develop carbon from the gas and then stop reading properly. You can test the measurement if you had an electrical meter (uA is how it would be listed on your meter- most basic meters have this function).
Let me know if this works, if not I have another solution you could try (I'm pretty sure this will do the trick though) James

Ignition problem: I have a gas hot water system: RINNAI CORPORATION; MODEL:REU-2008W-A the panel display temperature as 40C, when open the tap, the temperature display dropped to 12C, and no...


This is an error code 12, not 12 degrees. You have a short on your low voltage side by the sounds of it.. First disconnect the controllers inside the heater. Turn of the power first, 2 screws top and bottom to take the frnot panel off. Follow the low voltage wires (not the power point ones) to the PCB on the ride side and disconnect them both. Panel back on, power on and try the heater again. If this fixes it you have a short circuit in the controller or the wires leading to it. If not the most likely short circuit is on the thermal fuse which loops around the heat exchanger. This will need an expert, Perth has plenty north and south of the river. Give Rinnai a ring first, they have some good staff in Perth who might help.

I need a service manual for a Rinnai Infinity 26 continuous flow hotwater system - REU-VR2626WG-AK Can you help me? Linda


I left Rinnai only about a year ago at a levle of State Service Manager. I had been asking for service manual for for many, many months. Basically as far as I am aware there is not a service manual for the WG. If you google Rinnai Infinity 26 manual you can get a PDF from the Rinnai NZ sales site but his dates baack to 2003. Unfortunately there are major changes to some of the components but it might be better than nothing. Just don't use part numbers, and you might find bits to check that now have voltage and resistance differences. Send a message to Rinnai complaining, I encouraged people to do so even when I worked for them!

I "think" I have pinpointed the problem but want confirmation before I buy this part. the sequence of "lighting " the pilot is working fine and the water flow is circulating as it should. when I "turn"...


To keep the Pilot running... TYPICALLY the instructions say hold the pilot down for 30 seconds to allow the thermocouple to assume control... If extending that 30 seconds a wee bit does not work and your "pilot" keeps going out...

You have indeed found your "trouble"

The obvious defferences being length (first
(see generic parts below)

Follow the instructions on the replacement &
- DO NOT overtighten...!!
