Hey everybody, I recently picked up a raypak 130A cheap locally knowing it had issues with staying lit. That said I'm very technically savvy and I anticipated the issue being something very simple, however I am a bit stumped at this point!
I had a gasfitter plum the gas to the unit this morning – we used three-quarter inch line a short distance from the meter before downsizing to half inch, so there is no pressure issues for sure.
Issue is that the unit seems to function as a normal – power switch on, the unit powers up and about 10 seconds later the gas valve opens and the DSI Ignitor fires off with its customary buzz. The unit lights and burns well, however after only two or three seconds the gas valve clunks shut and kills the burners
Based on my previous experience this symptom points towards a thermocouple that isn't sensing flame and is assuming that the burners have not lit, thing is I can't seem to find a thermocouple anywhere on this unit! Obviously the unit must be sensing if the burner has or has not lit somehow, but exactly how that is getting accomplished is lost on me, but sure seems like that's the issue.
Any thoughts?
