Hello all,
I have the above boiler which I have been servicing for the last 5 years.
Every 7 12 months or so it starts playing up, getting smoky and locking out. It gets a new nozzle and a Hoover, set up with a FGA, works well.
I serviced it 2 months ago and decided to try a different nozzle, its always had a Delavan .65 60w. This time, I tried a danfoss .60 80 eh, set it up, running 12.4 co2 as per manual and 55 co @ 110psi, thinking in hindsight the co was a little higher than usual but still acceptable.
Its been fine all this time but Now 2 months later it wasn't firing and smoking so I stripped it down today and it's totally sooted up..! Worse than I've ever seen it. So I've cleaned it up and got it working again, it's not great and the FGA results aren't great, as you would expect.
So what happened? I've got to order another nozzle but which one? Go back to the Delavan or get a danfoss .60 80 s? as per manual?
Any help would be appreciated, thanks.
