high analyser readings on greenstar

[buckley plumb]

Went to do a service today on above boiler. Ration was 0.0021 and ppm was 222. Co2 was at 10.3 which is within the limits stated. This is AR then hey?

It also had a burst expansion vessel and is under warranty so turned boiler off and told them to call Manufacturers in to fix.

had very similar yesterday on 28 junior ratio 0.0021 / co2 9.9% / but ppm was 209 Worcester state 200ppm max . flue ok and did flue integrity check on air and was ok and heat exchanger flow was good .

Which greenstar would help? Also did you check low and high? Also in test mode or results don't mean a thing!

Also guys don't get hung up on 200ppm on WB they have just upped this to 250ppm on cdi and Si compacts, due to non adjusting gas valve, this is on a flyer as main MI's ain't caught up yet
