Boiler:
Camray 5 circa 2001, oil, non condensing

Symptoms:
It seems to be on, and yet it hasn't fired. Sometimes after tens of
minutes it does, and then works fine.

The flameout/lockout *doesn't* come on. (although it did twice in the
high winds)

There is oil in the tank

It sounds as though the oil pump and air blower are doing their stuff.
Not sure about circulation pump, but water is cold.

Any ideas?



Are you able to hear the igniters?

that's the odd thing, I don't think I can


You may also be able to check whether the coil gets volts so that oil is
released into the boiler.

If the motor runs properly for 5 minutes and does not light or lock out
I would be suspicious of the control box.


Yes...that makes a lot of sense.

Its a riello burner...what do they have?
