Where is the bleed valve on my oil-fired boiler?

[Ginolard]

Hi everyone,

We have an OERTLI OES 150/152 LE boiler (see the pics below). We ran out of oil last week and had it filled up but the boiler is not firing. From what I've read I need to bleed the boiler to let the air out and get some oil in. However, being about as clueless about DIY as anyone could be, I don't see where the valve is. Can someone locate it for me using these pics?

Edit: Quick note on the 3rd pic. The pipe WITHOUT the red circular handle has a small, ridged nipple-like connector on the end (as if you'd attach a small piece of hose to it). Would that be it? Or is that red circular handle on the other pipe the bleed valve?

Many thanks

One of the braided metal pipes is the oil feed and I think the other is a return. I would get some rags down and a plastic tray or similar and get a spanner and crack open each of the pipes until oil is running into your tray. Then tighten up and remove tray and rags and clean up and then attempt to light the burner.

On the fuel pump. Top right marked P. Loosen and allow the oil and bubbles to come out of it when you run the burner.

The flow is the right hand union.....depending on the orientation of your tank, you may need an oil syringe to pull the stuff through.
