Boilerhouse, smokeless, Thank you for the suggestions. I have treated the oil so I kind of figured I can rule out moisture in the oil but one never knows. I checked the screen on the pump and it was nice and clean with exception of a few tiny particles. But, I now have bigger issues. One of the times it skipped, the relay sounded like a rapid fire, firearm and then everything went quiet. I checked the circuit breaker, it's working okay, I cycled the on/off switch to see if it would reset and nothing. The only noise I hear is from the transformer in the zone controller. As a test I decided to turn on up the heat to see if that made any difference, it didn't, nothing happened; the burner did not run, the circulator for the zones did not run, nothing happens. I fear that the rapid misfire may have done something to the triple aqua stat (Honeywell 8151). If I didn't need to be at work for an important meeting with the bosses, I'd stay home do some troubleshooting, but this is a meeting I cannot miss. So, I have a call into my HVAC guy begging that he make room for me today to get this thing going and get me hot-water. He knows how to get into my home without me being there. I hope to have an update for you guys this evening. Roger
