Bleedinn unidare jetmatic boiler

jeff lebowski

Hi,

Can someone give me a few pointers on how to bleed this boiler? I can't locate the bleed nut on it.





We ran out of oil so it became airlocked. Had a new delivery today, now need to get it going again.

Thanks.

On the second pic it's the bottom nut loosen it till you get some oil.
Under no circumstances touch the top one it's the pressure adjustment screw

I turned the central part of the top nut a few times to the left, then turned it back before posting. Would that cause a problem?

So with the bottom nut, I loosen than then fire it up until I get some oil?

In a nut-shell, Yes.
This is for adjusting the pressure that the oil passes through the burner nozzle.
Incorrect settings can cause different problems, from the boiler simply not starting, to causing damage. It also screws up your flue emissions, which can in turn can increase your carbon monoxide levels.
You will now need to get an oil tech in to set things right and to carry out a flue gas analysis to ensure that everything is in order.

I think your boiler is very much in need of a service.It seems your burner is not running correctly .You may need to replace seals and gasket too.There ia alot of black soot above you burner.If you post a picture of your full boiler it would help to verify

Got it sorted, thanks

We told you how to bleed a Riello four years ago.!! (sorry I couldn't resist)

It will need a service as you've adjusted the pressure screw. For safety and efficiency. Chimney is the best indicator, you should be able to put your head close to it and comfortably breath, (if its low enough)!

Chances are, it's spewing out carbon monoxide. But shur it's goin

hopefully not but who knows

Well done,you got it going..,I just think a service would extend the lifetime of your boiler,make it safer for your yourself and family and possibly save you 20 percent on oil.Reason..,the amount of soot i see on your picture.
p.s, im not sure if a 20 percent saving is a realistic figure on fuel saving if it was serviced correctly..,maybe one of the other techs here could put a realistic figure on it

Looking at all the smuts around the burner, I would say that is a realistic figure. It would equate to between €150 and €200 per 1000 litres of fuel. Those smuts were there before the pressure was accidentally changed, so it could have been made worse (or better). But the correct settings are not going to have been achieved by accident. A proper service would soon pay for itself in a short time.

Well a flame is most efficient when its smoking!!!


It just isn't practical of course...

I don't follow that reasoning. Smoke is caused by unburned carbon. Carbon combining with oxygen is what produces the heat. The unburned carbon therefore represents a loss of usable heat.

That was a different house, this boiler is different and ancient and wanted to check.

I didn't say I got it goin, I said I got it sorted.

Landlord had it serviced and taken care of....."got it sorted". Bleeding it did not work so was some other issue.

Thanks for the help all.

It's rented accommodation and the boiler is ancient so if it was my house, I'd get a new one installed. The current one is in a detached garage.

They have sorted whatever the issue was and if I needed to bleed it in the future, boards have shown me the way :-)

Have a look at the flue and see if there is any smoke coming out. Doesnt mean its setup correctly if there isnt, but it does mean its not setup correctly if there is smoke coming out.

jeff lebowski

Thanks, will take a look for that when it's on today.
