Question about Heating & Cooling
I have a propane tankless heater and recently, after about a year of top service, it will not stay on. When you ask the unit to start up & run, after a few minutes, it will shut down completely. You can turn the unit back on but, the same thing happens again & again. What could be my problem ?
I have a Paloma model RUTG-74PVP, I had the same problem after less than a year. The unit would operate for about 90 seconds and then shut off with an error code of C13. Paloma kept trying to blame it on "lack of combustable oxygen" ,, my unit is in the attic, so we added more soffit vents and an electric attic fan. We still had the problem and Paloma blamed it on the lack of a condensation trap (so I added one), & then on the 1" dedicated LP Gas line (so I had the propane guy come run a water column test). Finally, 4 months later , Paloma had a service man come down (100 miles away) to see what was wrong (He told them to replace it. They paid for the unit and labor. It ran perfect for about 9 months and then started doing it again. So I called the same representative and asked if they were gonna replace this one too? He said nope, it's no longer under warranty. But he did tell me how to fix it this time. It required taking the the whole unit apart and cleaning a ceramic piece in the very back of the heater. It was hard to get to, and it took about 2 hours of disassembling and reassembling. The good news is Paloma will walk you thru it on the phone and once it's was done, my system worked properly again. The bad news is,, it only lasted for about 9 months. So now I need to do it again. I'm hoping that someone will read this and tell me that there is a filter (like a gas filter) that I can install that is easier to get to.
