Hi All,

Apologies for not being around much, life keeps getting in the way!

We have the builders in (the job is too big for me, calls for experience I don't have, and time I don't have). A couple of days ago, he severed the oil supply pipe while breaking up and removing a patio.......

He has done a temporary repair, and it seems fine.......

However, there was a lot of air in the Line.

The boiler (the original Wallstar conventional (Non Combi)) boiler is mounted approx. 3 -4 feet higher than the current level of oil in the tank, and it normally pulls through the oil just fine (no need for a tiger loop).

I THOUGHT that I could just keep pressing in the orange light on the lock out relay thingy while it sucked the oil with air pockets through and once it got all the air out of the way it would be fine. This approach appeared to work. Then after a while we noticed the boiler wouldn't fire, and no amount of pressing the relay would entice it to.

I couldn't find the instruction booklet, but found something on Wallstar's web site which said......... If you pull air through it, you will have to replace the nozzle. Now there is what I presume is a nozzle just inside the casing (I assume it is an old but functional one left there by the service engineer.

Questions.........

How SHOULD I have got the air out of the system (or was that the correct/only way)?

How easy is it to replace a nozzle? (and how do I do it)?

Sorry, I don't have details of the burner to hand, it's small ish, the left hand side of what you can see is silver and looks like (but probably isn't) an electric motor, and the right hand side is red. The whole lot (of what you can see from outside the house (the boiler sits in/through the wall) is about 9" square and goes back about 8 inches.

TIA
