I noticed today when fitting new Worcester compact that the servicing instructions now say gas valve has no adjustment, and if the co2 levels are out on annual servicing then a replacement gas valve is needed!!!
The gas valve still looks to have min & max adjustment screws, but I am wondering why we are no longer allowed to adjust them! Is this the way all new boilers are going now? Or have there been cases of boilers being adjusted incorrectly & causing masses of co2???
