I have steam boiler that provides heat for pair of large tanks and burner is constantly shutting off during first hours of runs.
These are few observations I noticed so far, any help is appreciated:
1. Burner shuts off after couple of minutes when I start the boiler-maximum 0.5 bar pressure is reached. It shuts off continuously for first 2-3 hours of running, then it runs fine.
2. Pump runs until boiler is completely filled with water even it should stop when there is 70-80% level in reservoir so it is full of water most times.
3. I piped condensate trap and water reservoir, but water leaving steamtrap is pretty rusty since valve is iron made.
Similar model as this one: http://bellgossett.com/steam-specialties/traps/inverted-bucket-beartrap/
I assume this not quite good for boiler as it requires softened water.
Unit is almost new and provider/service is little help.
