Bleeding oil boiler

WicklowTiger

Hi all

Ran out of oil yesterday, got a delivery today but boiler won't start. Assume it needs bleeding, but not sure how to go about it. Any help appreciated. There are two nuts I can see, I think one of these needs to be turned. I also recall a plumber one telling me not to turn the other under any circumstances. But I don't know which is which! I've attached a photo which will hopefully help

Thanks

This is the one.



Loosen it back about a turn or turn and a half. Oil and air should dribble out. You will need something to catch it in. When the bubbles cease, leave it open only about half a turn and press the reset button. be ready to turn the bleed nut closed, as it will squirt oil all over the place as soon as the boiler fires up. Make sure to check for leaks a few times after bleeding it.

On another note, the slotted screw above it (which should never be touched) doesn't look to be in the correct position. Can you post a profile photo of it, so that I can judge it better?

Many thanks that's it! All sorted. Regarding the other nut, not sure how clear this will be but below is a profile shot

Looks to be too much pressure on that pump, but hard to tell without having a gauge on it. Maybe some of the other lads might comment on it.

Glad you got it going. Judging by the soot that I see in the first photo, it looks like it could do with a service.

Thanks again, yes will be getting it serviced...

Agree with Wearb - Unless you are on Gas Oil (Diesel), I would think that the pressure setting is much too high.
