Ok, try this one on;
pre-1995 Heat & Glo 6000 GDV thermopile only valve. Pilot was cruddy and homeowner asked to replace valve, pilot, pilot orifice spud, and thermopile. Fired up unit fine but started ghosting. Damn! Those sloppy vents when HG first went to Simpson DV pipe. I've repaired hundreds of them. Silicone the outer ring & rope gasket then furnace cement the inner sections. Outside, yep, inner sections separated. Tore vent apart, rebuilt Humpty Dumpty then ran inside to test fire. As the condensation is almost completely burned off, I say to the homeowner this was about the point the unit would ghost out when....."click". Dammit! Now,what?
Got my kit, set up readings: 6.78 static inlet drops to 6.02 burning and 5.25 full load in house. 550 mv open, 235 closed. Removed all switching wires so just TP connected to valve. As soon as I jumped it, "click". Fine, I'll fix your widdle wed wagon! Removed TP, installed AA battery pack instead of TP. Jump it at valve, "click". DAMGUMMITT!!! Getting desperate as this is Dec. 23rd 5 pm and I have 3 more stops and another 100 miles to go. Replace valve. AA battery only jumpered--'click'. New jumper wires, "click", tried 2nd new TP, "click". No matter how many valves or TPs the second I closed the contacts, it would drop that bugger out.
Still unresolved. Ok, you guys tell me, what in my panic did I overlook? I know this is a short trip for me but I'm going nuts!
