baxi solo 2 50pf FGA

[ryan3]

Hi everyone i am just after getting my baxi solo 2 50pf boiler serviced by an RGI i got a print out of the FGA readings when he was finnished and they are as follows

O2 (%) 11.2
CO (ppm) 46
CO2 (%) 5.5
Ratio 0.0008
Pressure (mBar) -0.08
Temp net (C) #####
Temp flue (C) #####
Eff net (%) ####.#
XS air (%) 115.6

Do all theses readings look right for a serviced boiler? And how come i cant see how efficient the boiler is? Any Help

They do look OK, but your Engineer needs to get the Temperature probe on his analyser repaired, as no flue gas temperature is recorded on your print out, nothing for you to worry about though!!!

 

[mickyg]

it don't tell you how efficient it is anyway. pointless.

He could have just forgot to plug in the temp probe.

You can't get an efficiency reading without the temp being recorded.

I take it you don't trust him then.

If the figures were wrong do you really think the engineer would be foolish enough to document them and pass you the evidence to keep.

If there were any concerns the engineer would either take steps to remedy them or make the boiler safe.

No its just that i know a bit about oil boilers and FGA with them and the FGA is a lot different to oil that was all. Just being safe

You might know a "bit" about oil, but clearly you are no Combustion engineer?

I actually know quite a lot about oil burners, i service and repair them but as you quite well know oil and gas are completely different and clearly i know very little about gas. Thats why i stick to oil

Apologies to you Ryan. Now can understand the interest.

Ryan as an oil engineer , surely you understand CO2/CO Ratio?,so you should have been able to appreciate the FGA print 46ppm CO and 0.008 ratio should have put you at ease, and as someone who must use a FGA to set up oil burners, you must have realised that without a temperature read out the FGA cannot calculate flue loss and combustion efficiency??
