Bit confused here boys and girls.... 200 PPM???? Ratio 0.0022???

[MrBassi]

Hey guys,

Need abit of clearing up here....

So earlier today was sent on a service on an Ariston Microgenus mffi 23 GC No. 47 166 14 (to be precise)

O2 = 4.2
Co ppm = 205ppm
Co2 = 9.5
Co/Co2 Ratio = 0.0022

Im quite surprised to see that my Ratio seems sound however my ppm was above 200ppm????

can someone help me out here whilst I scratch my head...

9.5 co2 ... Is this a condensing boiler?

 

[MrBassi]

Not condensing, Room sealed, Combi boiler

a room sealed condensing combi boiler??

the ratio is not that good to be honest, whats the manufacturers recommended readings?

welcome to the forum

 

[MrBassi]

Thanks for the Welcome,

not a condensing boiler..

well this was just it, according to the Mr Combi app on the iphone all is fine and boiler doesnt need a service but when looking more into it still not too sure as MI states:

51.9ppm
o2 = 7.5
Co2 = 7.2

.... yet im getting over 200ppm and still within limits!....lol

 

[Atouchofgas]

Well obviously not within limits if mi states 51.9 & 7.2. So it needs a strip down

 

[MrBassi]

Stripping down first thing tomorrow
