I have a Riello G3X oil burner. The injector in it is a Danfoss 0.55 80H, but in the box of spares left by the previous owner there is a 0.55 80S & 0.55 80ES. Can anyone tell me which one i should be using & what is the difference between the 3 nozzles. Thanks Ian

Hi Ian,

Difference in the nozzels is spray pattern...

.55 (us gal per hr) 80deg is the spray angle
S= solid h= hollow es= extrasolid

The one you should use should be specified in your boier manual (not burner manual)
