base of boiler filled with oil ......what is going on here?

[apcdave]

Hi all,

Just quickly...fitted a new Riello 40 burner about 5 weeks ago and all was fine until get call today to say customer had run out of oil but since oil delivery the burner was not firing up. Thought might be just a quick case of bleeding the pump but when I got there I found the base of the boiler full of oil maybe an inch deep.
Not seen this before - has the solenoid valve remained open allowing oil to seep thro the nozzle? Looks like a major clean up job tomorrow...

Any help much appreciated

thanks

Seen this before where the boiler was overaired and snuffing the flame before it could ignite. Also, thake a sheet of 13mm ceraboard with you to replace the base.

Simple to prove if it is passing through the pump, - just pull the burner out, (electric off!) point the blast tube upwards & dry the end of nozzle with tissue paper & watch it for a minute to see if oil rises out.

2 obvious solutions, possibly overlooked:
1. Leaking hydraulic ram?
2. Punter been trying to bleed it?

Can't be ram leaking if the oil is inside the boiler shell.
You do get the odd idiot who presses the lockout button a thousand times in a few hours, "just in case it might start" & puts oil inside the boiler.

Sorry, misread the post - of course you're right. I was thinking of Firebird super Q bottom tray.

Well I've just got back from this one - even with the power off , oil was seeping thro the nozzle. I changed the solenoid but this did not fix it - even changed the control box but still no change. What else could it be boys? Surely not just the nozzle?

The stem not the solenoid.

You say you fitted a complete new Riello 40 burner? It will have a 12 month warranty, so it should be fixed or replaced free of charge.
The solenoid valve (the stem), not the solenoid, may be faulty. Might be best with a whole oil pump, but will you get it free if you change it yourself?
What height is the oil tank above the burner?
Piece of advice, - rather that fit a Riello 40 burner, use an Electroil Sterling burner IMO.
