Rinnai 2001 natural gas heater

is it a vented unit? sounds like if it is, the exhaust or intake is blocked which is causing a high limit to open until it cools

hi the heater was on ignite but the flame didn't ignite it when bang will it start up again I turned it off

Try national energy they sell convestion kits It would need a gas fitter to do the work , you may need to a quote on this , they would be able to tell you if it is worth it ,its hard to tell with out looking at the heater .

I suggest you call for service. This "bang" could be a serious problem in the future - meaning the next time it tries to start.

Is is propane or natural gas? If it is propane, i would check the supply pressure.

Unfortunately, Rinnai only sells repair parts through their authorized dealers. Contact the dealer you purchased it from. If you are not the original owner of the home/heater, you can go to Rinnai's website and search for a dealer near you. http://www.rinnai.us/direct-vent-wall-furnaces/

12 is a fault code, look in the book if you have if, i think 12 is no or low gas pressure, cheers

No conversion parts available since 2005.

Hi sammysamual,

My business is Laser Heating Service in the North Pole/Fairbanks areas of Alaska. An EE2 error code is usually fuel related. What does your Toyo do before the EE2 code shows up? The firing process is the burner button blinks green for 7-9 minutes, then it clicks up to the medium, yellow light which starts flashing. That is when the fuel pump starts pumping. If you hear a fairly audible tic tic, or thump thump coming from the fuel pump then that is your indication that the fuel pump is starving for fuel. You either have a fuel line restriction, too little fuel, a clogged filter, a clogged sump screen, or rarely, a failing fuel pump. Usually, it is a fuel line restriction.

If you hear no tic tic or thump thump and it just goes off on EE2 then the problem is in the burn chamber. You may have a carbon chain in the chamber causing the flame sensor to temporarily short out. You can clean the flame sensor, fuel nozzle, and igniter to resolve this problem until you can get your Toyo tuned up.
