How to Commission a glow worm betacom 4 30c combi

The tolerance for the co2 9.2-10.2% for max and minimum. I don't know why this is not stated in the manufactures book.

The tolerance is 8.2% - 10.2% and it states it on page 20.

Still not very clear. Maths weren't my strong point..
Would be happy with my readings?

ppm bit high would really want it under 150 on a brand new boiler

Yeah I know but any lower the co2 goes down. Would you recommend me going back and adjust the setting?

 

[ShaunCorbs]

no would recommend adjusting i would get gloworm out tbh

at the same time you could have 14mb at the boiler and 15mb at the meter which is perfectly acceptable so test it.

Please explain to me how 15mb working pressure at the meter is acceptable?

How isn't it? In some areas of the UK where the gas network is stretched, during peak times that's all you get, for this reason boiler manufacturers have been forced to ensure their boilers function properly at pressures down to 14mb.

Eg middle of winter

Spoke too glow worm technical they said it's within the parameters so everything is fine.
