I apologize if it looks odd that I'm replying to my own posting, but I solved the problem. Actually, the safeguards of the system worked properly. The cause - mud wasps build a nest in the exhaust vent pipe, severely constricting the exhaust. As pressure built up in the pipe, the blower vacumn switch opened - causing the burner to shut down. It did what it should. I removed the nest and all is fine now. I hope this information may prove useful to someone else someday. : I have a Rheem PowerVent gas hot water heater. This mode has electronic ignition. After the power vent turns on the flame ignites for approximately 5 - 10 seconds and then turns off. Any ideas on what could be wrong?
