this is all I could find it looks like an earlier model, but it may be helpful. sorry it is such a long link. it's the download link for the manual, hope it helps. http://www.google.com/url?sa=t&rct=j&q=rinnai+natural+gas+heater+manual+avenger+RCE+670&source=web&cd=3&ved=0CC4QFjAC&url=http%3A%2F%2Fwww.finesgas.com%2Fproduct_extra_files%2FRinnai-RCE-592.pdf&ei=rzZgUMbfKpLI9QTwx4DwCQ&usg=AFQjCNGPoBENsIVWy_-1GG94mowsXBSosg&cad=rja
This unit can be vented through the roof but requires a specialized flue system-do not use an existing flue connection. Call a contractor - have them check and see if the unit can be modified to a vertical flue- it will require the existing piping to be replaced--Not a job for a do-it yourselfer
You could have something as simple as an air hose off, or a piece of carbon on the flame sensor. Your problem could also be a gas valve , which is much more complicated. If you are handy with tools you could be able fix either quickly. If you’re not good with tools you will need to get some help. Either way you have to have some back ground info on your heater. Get in touch with Rinnai and get a service manual for your unit. They cost around $15. If you have to call a service guy, use the Rinnai web site to find an authorized service person. Don’t just let your fingers do the walking and get some guy who has no idea what a Rinnai is. You’re only asking for trouble there. Your unit is a little older so don’t be surprised if parts are hard to find.
Is there a chance there is a draft around the room temp probe? It is down low on the right side of the heater. If there is a draft the room sensor is fooled and keeps running the unit. You should be able to prove the room sensor by putting your hand over it after the stove has been running for a while. This should shut the stove down. If not there is a problem with the room sensor.
