Hi there I am trying to help a friend who has a slightly older version of the Rinnai Timberflame Centrum and he was cleaning the controls on top of the heater and in doing so has pressed one of the buttons, unsure which button, but now when he turns the heater on it only stays on for 10 minutes and then shuts off. I told him to turn it off at the mains, but it has made no difference. I'm guessing that he has pressed a button involving the timer, but don't know how to stop it cutting out after 10 minutes? We would welcome your solution, thanks Sue.

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 ;)

Sorry Ken I worked for Rinnai Australia as a service manager so treat my advice with a little cuation but you should find the basic universal controller should work fine. The code over here is a MC-91 Q2A. It will MC-91 sometihing for over there (I'm guessing from the codes you use you are across the pacific!). You can wire this unit either back to the heater or to wiring from another controller, just match the colours and link them in. Power off the heater first but it is all low voltage.

I found 1 on eby with a slightly different model prefix BC-45-4US
but it should do the same job! heres the item number 280639936016 so you can search for it on ebay

It's likely that the burner mat has came loose or it has a lot of carbon buildup in the burner. Look at the flame when the heater is on. It should be mostly blue with slight yellow tips. You might need to clean the fuel nozzle also. You can remove the fuel pipe where it connects to the burner and use a piece of wire or an allen wrench that will fit in the nozzle that goes into the burner to remove any carbon that may have built up. You can also clean the burner but don't destroy the mat in the bottom. You can find the owner's manual at toyostove.com and it will give you some more things to clean.

It is true, there are none available. Are you sure that it needs one? what are your symptoms? I may be able to help.

I would try going to <a href="http://www.download.com">Download.com</a>. You may be able to find an older version there that you can download for free. Yahoo may even have older versions for you to download.

Try disconnecting the unit and thoroughly cleaning the dual walled intake and vent pipe that goes through the wall. Use a small brush to make sure the passages are free from any obstructions. These units have safety mechanisms that are very sensitive and sometimes will shut off when something as seemingly insignificant as a leaf or spider web creates a slight blockage. A yearly inspection and clean out are necessary.
