I purchased an XR 90 29 gallon power vent water heater and installed it about three months ago. It was installed per the directions with proper venting. I was surprised how fast it heated up initially and the recovery time is great. However, it continues to trip a 6-3 code indicating the flame is lost. It trips the code about once per day. Richmond has sent several new parts including a gas valve, blower assembly, and ignition assembly. None of these parts fixed the problem. I'm extremely frustrated to say the least!! I spent the extra money for a higher quality unit. The store where I purchased it is two hours away and they will only exchange the unit.
They emailed a more detailed troubleshooting guide recently. I noticed there were problems early on with burner assemblies but this didn't apply to mine. I measured the distance between the pilot assembly and burner and found it was about 1/2 inch off spec on the two points. I bent the pilot assembly closer to the burner and it' close to spec but i don't want to break the weld. It has been about one day and no issues yet...
Has anyone had similar issues?
