Rayburn PJ Ecoflame burner

[Peter.N.]

Hi Folks, I wonder if someone can help me. We have the above installed and its taken to firing up, running for a couple of minutes then the flame goes out followed by the cut out. I loosened the bleed screw as soon as the pump had stopped expecting there to be no fuel but there was but only a trickle.

Do I have a fuel line/filter blockage or could it be the pump, yesterday it was occasionally making a scraping noise like a dry bearing then it stopped, its only started cutting out today.

Is there a filter on the burner? I haven't checked the tank one yet because its a distance away and its pouring with rain.

Thanks

Peter

Could be the solenoid coil or motor.

If it relights ok when it locks out I would suspect the solenoid coil as this usually fails when it starts getting hot.

Do you have oil in the tank? It helps!

 

[Peter.N.]

Yes about £500's worth After I bled it, it ran for sometime and then went off again. I have noticed that sometimes the flame goes out and then reignites before the trip goes. I will check the tank filter tomorrow.

I would suspect that you either have a clogged filter in the oil pump or water in the oil.

I thought water to be a possibility but there was no sign of it in the fuel I drained out. Where is the pump filter, in the intake pipe?

It will be within the oil pump body, will need the pump make and number to give more details.

If you have a danfoss pump, there is a filter that is accessed either from the top of the pump via an allen screw, or you will need to remove the cover of the pump via the 4 allen screws. If there is water contamination it will be obvious here.

Pump is a 'Monflame Minor one S' It does have a little tower with an allen screw in it next to the bleed screw, is that it?

The Mono 1 is the burner not the pump. The oil line is attached to the oil pump by a hose. It will have a name on the side which I think will be danfoss bfp (number) then a letter and another number. I would check for oil coming to pump first. Do no touch the allen screw tower as it sets pump pressure and if you turn it you'll knock the flame out of balance with air intake.

 

[Peter.N.]

Right thanks, I will check the tank filter first.

 

[Peter.N.]

Thank you all for your input, it now seems to be working OK.

I checked the tank filter which was a little dirty but not blocked, I then tried to find a filter on the pump but as access was not good I removed the burner, I carefully examined every orifice of the pump but could find no filter, the inlet port did have a bit on muck in it though. I disconnect the fuel line and ran it into a container, the flow was very slow, I jiggled the plunger thing on the fire valve and some muck came out and an increase in fuel flow, I drained about half a gallon off and the flow improved considerably, I have now put it all back together and it has been working all afternoon.

So here's hoping.
