Oil Boiler Won't fire after service

[Adam2050]

Don't be too surprised if your pump is dead they really don't like that sort of crap .
We would just replace.

Yeh do fear that but how would you know.
It's still not running.

Boilers are often routinely left idle for ~ 5 months of the year if not used for reheating a HW cylinder so vital IMO to fire them up for even 5 minutes every fortnight or so, I do this with mine since I have Solar Thermal and I havn't had a single (not one) combustion failure in 19 years, probably helped as well that I've never left my kerosene tank run dry, still though pretty remarkable, a Riello G5X burner in a Firebird 90S SE boiler.

Defo learning that the hard way.
I mean it doesn't look like it was ever serviced properly other then calibration and nozzle. Could of avoided this whole situation.

I really wouldn’t give that pump a second chance......it needs replacing now.
Start at the tank filter / water separator , run some kero through afterwards to see if it’s clean.
Work on to the burner, consider another filter before the kero enters the house.
Pumps have their own filters too, and there’s one on the back of the nozzle too.
Replace the nozzle, they are made under clinical conditions and don’t like to be interfered with.
Good luck with it!
