Reluctant Riello

[Baz2126]

Hi Gents,

I'm not an engineer (I'm the owner) but I've had two qualified engineers on the job plus Grant's engineer by email (not very effective) and a technician from Riello's by phone (better than Grant's). Any tinkering with settings will be done by qualified people.

Thanks
Baz

As I said in my previous post - is the tank at a lower level than the boiler?

 

[Baz2126]

Is the tank below the level of the boiler? If it is then you probably have a leak which is allowing air into the line and the oil to start to slowly run back down into the tank, causing the lockout when the air starts to get drawn into the burner on startup. If you press reset a couple of times you will probably clear the air to get the burner started, but when it stops you will be back where you started the next time it tries to fire.

You can find such a leak using a plumbers hydraulic pressure test pump.

Thanks WHPES but tank is above the boiler.

Are the baffles in correctly? Flue location? Back draft down flue?

Filter elements clean?

Plenty of " qualified " in oil guys, but getting one that is really good may be harder!

True of too many things nowadays 🙁

That's the difference between a technician and an engineer.

You could try a long-establised company (look on the OFTEC website to find registered companies in your area). Ask your oil supplier for a recommend.

Yes baffles have been out, checked and replaced correctly. Filters are clean.

One of the engineers is the company that has serviced the unit for the last 9 years. They quickly ran out of ideas after changing a photcell and capacitator that had already been replaced. They haven't been back and won't be invited...

They haven't tendered an invoice either.

Sometimes even the most experienced engineer will get stumped for a while, but you just go about it by process of elimination.

Don't see how anyone would change the motor or the capacitor without knowing exactly that was at fault as the diagnostics for them are usually pretty specific.

People may think I'm a bit odd but I actually do like getting presented with these kind of problems as they are more of a challenge to fix. I tend to do quite a bit of troubleshooting of plumbing and heating systems and equipment.

As a Halifax lad myself - just how far North are you in Yorkshire?

Yes, sometimes a burner will be tricky, but sounds like in this example, the engineers weren't up to the job, & this burner just proved their lack of ability & perhaps experience.

Going by the process of elimination the only thing that hasnt been done is to check the co2 and make sure it is not over aired as has already been suggested and also have the electrodes been checked to see if they are shorting out on the blast tube or elsewhere, easily checked or you can see signs of tracking with the telltale carbon tracking.

Hmmmph! Electrodes? I checked the gaps but never looked for tracking... I''l be having a look then!

Dont forget the leads as well

 

[Baz2126]

Thanks kimbo.

I think this forum is fantastic. Since I posted the thread the boiler has not stopped running! That's the first time since early January!!!

I should not have said that!

Hi,
Many thanks to everyone that contributed help in this. The system is still running since fitting the Tigerloop but I think that the real culprit was the flexible hose feed pipe to the oil pump. That was changed when I fitted the Tigerloop.

Your comments on gas and air settings have been noted any on any further problems this will be tested first - by qualified engineers of course.

Thanks again

Baz

Spoke too soon! It's locked out again. Now getting estimates for an LPG boiler...

Hi Folks, gas readings taken today:

02% 5.4
C02% 11.5
C0 ppm 40
Flu 0C 235.4
Inlt 0C 15.3
Nett 0C 220.1


Eff (C) 90.2
Losses 9.8
C0/C02 0.0003
PRS moar 0.00

Is this normal?
