A case of bulls**t baffling brains I fear (what a load of tosh!!) :LOL: :LOL:
If you mean Trianco bulls**t, then I agree, but taking my most recent example of a Eurotrader Premier for 125,000 Bthu, the original data sticker gave a 1.10 x 80EH nozzle at 125 psi. The revised sticker gave a 1.00 x 80EH at 105psi, which is exactly the same as the original sticker data for 100,000 Bthu. At the same time it was necessary to remove the air diffuser plate which was fitted behind the nozzle on the earlier Max burners. It was not mythoughts about the increased calorific value of the oil ( by the way, the extra quantity of oil to replace the sulphur is only .001%) but what I was told by Trianco. An earlier poster was also told this.
If one goes back to basics, learnt many years ago, then a 1.00 gall nozzle at 105 psi on 28 sec oil will give a gross Bthu of 161,000 approx, so a nett efficiency of 90% would still exceed the stated 125,000.
LoL if you like, but it is obvious from the comments on this and other forums that Trianco got something very ,very wrong in their original design.

i would check you calculations again as they are very wrong even the danfos nozzel caculator does not com up with your figure and this is approximate. you need to know the amount of oil used in seconds and the calorific value to accurateley determine the input. plus the calorific value of my last 4 tanks of oil have ranged from 42.4 to 44.2 and standard is 43.3 so you do the maths and this can cause an significant increase in input. not to mention a gauge for oil pressure not reading correctly ( slightly out ) plus the nozzel tollerance of +- 5%

:evil: Glad to see we are not the only ones stuck with an f****ing useless boiler. Bought in Jan 2007 Eurostar 100/125, hasn't worked right since Oct 2007. Got the same run-around from the arrogant b*****trds at Trianco - sulfur in oil, etc., even two of their technicians couldn't keep it running. Had them in court even, but of course their slimy lawyer got them off, said we couldn't prove they were responsible for the boiler not working properly - go figure, a legal technicality apparently. Cost us £60 in fees, but cost them much more to defend the case, so some satisfaction there. At the time there were no posts about the lock-out problem, so we couldn't prove a design fault.

The only thing I can say to you is - DON'T BUY A TRIANCO BOILER!!! Junk Junk Junk! We are going to try a suggestion form an engineer - getting a Boash burner fitted via and adapter ring. If that doesn't work, it's going to the scrapyard.

I too have a Trianco Eurostar 110 boiler and have had nothing but grief from it. I bought in new in 2008 and it started locking out, after a few months, and the time between lockouts has decreased to less than a day, after an engineer has been out and got it going again. The baffles soot up a lot, but they are clean now and it still locks out. We have cleaned the photocell, changed the nozzle, cheked the oil pressure is 110PSI, checked the coil for continuity, tried adjusting the air settings and still it locks out after a couple of hours. HELP - any suggestions!!

A lot of the problem Trianco's I go to on balanced flues are recycling their own exhaust gasses either due to burnt/disintergrated seals or bad installation.

I agree with that 100% Trianco E/Star flue is one of the worst designs I have seen, while every other maker has gone over to round flues with silicon O rings which give a much better seal, Trianco stuck with old fasioned taped joints, which when combined with a modern Max high resistance oil burner causes havoc with recirculation!! :confused:

Unfortuneately I was away when Trianco eventually came out to my boilers.
The problem has got to be that the boilers are too tightly baffled, not allowing the flue gases to pass, so the burner head fouls up with unburnt oil.
I have asked for a copy of their engineers report, and also where an angle grinder is used according to their commissioning instructions. Someone on site at the time noted its use.
For a customer to be told that the commissioning engineer does not know what he is doing is unacceptable without a right to reply.
To be continued........

Hi Guys,
Just thought I would put my ten pence worth in! I have 3 customers Trianco boilers that give me constant grief! 1 Eurostar 100/125 thats does pretty much what everyone else is reporting lockout wise. Also 2 Trianco Iona's that do the same as the Eurostars do! Soot up very quickly, even though everything is set as per the book! Works fine while I am there and then about a week later... Do any other engineers have a copy of the 'Revised' combustion settings as Triance just sounded dumb (as usual) when I asked for them! OR has anyone got a name in the tech dept that can speak etc...

Cheers chaps!

PS Have to visit the ****ing Eurostar tomorrow! :cry:

Just gos to show I dont specify Trianco boilers! Did not realise and have not heard! Doh anyone know someone with those revised combustion settings? I have tried everything I know!

Cheers :eek:

When you say the Eurostars soot up, is this in the boiler itself, or is it the photocell that mists over and the combustion head that gets very wet?
Does you Eurostar have the large square baffles with a 25mm upstand or is it one of the older ones with an upstand of 75mm? The reason I ask is that you say you have the Iona's which are the first model Eurostars with a large gap between the baffles, and not normally too much of a problem. If they are balanced flue, make a small hole in the air tube and use your analyser to sample the combustion air and see if you have a leak in the flue.
If the Eurostar premier, then yes, check for flue leaks, but be prepared to use an angle grinder and open up the flue passes to about 20-25mm.
I have three sets of settings for them, so not much use passing them on.

My Eurostar Premier 100/125 was left with a 1.00 gall nozzle at 105psi. Aim for 10.5%-11% CO2. This is less than Trianco figure, but still keeps CO under 40ppm.
Also, if the burner has an air diffuser plate behind the nozzle, then remove it.
Good luck.

The first time I visited, the combustion chamber was full of soot but since then yes the photocell mists and the head is a little wet, no nozzle drip though with good cut off. What else have you found causes this?Does you Eurostar have the large square baffles with a 25mm upstand or is it one of the older ones with an upstand of 75mm? The Eurostar 100/125 has threaded rod as upstand and I would estimate they are the 75mm apart ones.The reason I ask is that you say you have the Iona's which are the first model Eurostars with a large gap between the baffles, and not normally too much of a problem. Not sure about the gap on these without checking.If they are balanced flue(yes they are), make a small hole in the air tube and use your analyser to sample the combustion air and see if you have a leak in the flue.
If the Eurostar premier, then yes, check for flue leaks, but be prepared to use an angle grinder and open up the flue passes to about 20-25mm.
I have three sets of settings for them, so not much use passing them on. Did Trianco tell you about this or trial and error? I have heard another engineer mention this in the merchants and also a few years ago doing a requal course. When you say 3 sets of figures do you mean for different outputs or models? Any chance I could have them to compare?

My Eurostar Premier 100/125 was left with a 1.00 gall nozzle at 105psi. Aim for 10.5%-11% CO2. This is less than Trianco figure, but still keeps CO under 40ppm.
I visited the Eurostar 100/125 today and reset the oil pressure to 100 psi on a 1.1 x 80 EH nozzle, set the CO2 at 11%. The CO was around 15ppm which I thought was going well for this one. Left the air hose off because the idiot that installed it hacked a standard flue to fit a single skin wall, it was leaking gas' into the air hose where the hack saw had mangled the tube! Will be returning to fix that one at a later date if the boiler runs ok for a while now.
Also, if the burner has an air diffuser plate behind the nozzle, then remove it. Will try that one, thanks.
Good luck.


Thanks for the experiences oilhead, going to need more than luck though I think!

I left the settings at the customers with the commissioning cert etc. so don't have them to hand. These were for the premier, but yours is one of the earlier eurostars, which normally dont cause a problem unless there is a flue fault.
With the air tube off, the problem of contamination should be solved, but I wonder if you have a butchered flue, whether this is causing back pressure. The 'wet' head is indicative of insufficient air passage through the boiler. If the flue is short, could you be getting backdraught?
I have one Eurostar where in the past, someone has fitted a shield to the flue to eliminate the prevailing wind, which seems to work well.
If you have a very low CO content, it may be worth lowering the CO2 a little if you still get misting of the p/cell.
Trianco have not been helpful at all to me, and I have leant heavily on experience and experimentation, but this, as I have said is on the Premier rather than the older Eurostar, where I've not had too many problems.
Just one last point, have you noticed any re-ignition during the boiler running times?

Heard in my local down here Peter Ferguson (MD when Trianco Ltd went bust in 2010 and MD when Trianco Heating Products went bust) is trying for a third time . Try ringing the old Trianco number , think it will be under new name though. Im sure he will look forward to solving your problems.
