Hi
I Have A Oil Boiler & A Riello Burner, When I Switch The System On It Runs For About 10-15 Mins And Cuts Out, The Pumbler Said It Was The Limit Switch I Changed The Limit Switch And Its Still Happing
Can You Help Please

Hi Carl,

When you say it cuts out?
do you mean the lockout lamp on the burner or the reset switch (high limit) on the thermostat?

I guess it's the high limit on the theremostat, if so, either the switch is faulty, or the capillary part of the stat is not in place correctly to fell the heat temp.

Or more likely, the circ. pump is either stuck, burnt out, blocked, or installed with the water flowing on the wrong direction.
