analyser readings

[gwplumbing]

hi guys i am new to the forum and would appreciate any help please
i have got a trianco eurostar,the readings are as follows
02 6.3
C02 10.8
C0 00 ?
flue 171.8
inlt 89.6
nett 82.2
eff 96.1?
losses 3.9
x air 43.1
co/co2 0.0000
any feed back would be a great help on readings
many thanks
boiler is working fine for now, it was set at 8.5 bar pump pressure and co2 was only reading 6.4,which is very low
mi states 7.5 bar pressure, but reducing brings down c02 even lower
alterd air to get back to 10.8 which should be 11 but other readings are out,
many thanks

...what exactly would you like to know? This is pretty vague at best.

have you done the oftec training?

thanks for the reply
i have done thy oftech trainning a while ago
trying to work out if my analyser is working properly (it has been calibrated recently)
co is showing 00
would like advice on readings

Low or no co shows its burning clean.
you should keep the burner pressure as per MI's for the nozzle you're using and adjust everything else on the air register.
they will give you a co2 value to get too.

it would probably been at 8.5 for a different size nozzle.

most boilers have 3 nozzle set ups given to give different kw outputs.
I would go back personally and make sure its set for the correct nozzle.

last thing you want is unburnt oil.

Thanks King
i replaced the nozzle it was as mi
i could not understand why it was running at 6.4 co2 after changing nozzle which was correct
