Hi all, i went to service one off these today but i had to abandon and say i'll be back in a couple of days. This has really throughn me badly and its the first time i've attempted to service one of these aswell so no prior knowledge.
A bit of background british gas have "serviced" it for the last 14years approx, i'm the first independent gsr the customer has had in since he cancelled the contract just under a year ago. I Checked the data sticker on the boiler and it said 12.1mb burner pressure, as i haven't done one of these i asked the customer if he had a manual to check minimum pressure. I was presented with this manual: Worcester 28 CDi RSF Installation and Servicing Instructions | Worcester, Bosch Group
I noticed the Gas valve looks nothing alike the one in the manual above but the 12.1mb correlated so i carried on.
When tested on DHW on minimum and i'm getting 4mb and maximum of 7.9mb which is miles off what the manual says.
So my first question is can it honestly fall out off range this quickly, as in a year since british gas was here. This has stopped me in my tracks as i've never seen something this old this far out.
Since ive got home ive found this manual for the boiler aswell, which the boiler in question has this gas valve:
https://www.freeboilermanuals.com/a...Installation-and-Servicing-Instructions-2.pdf
Which manual would you guys follow? The data sticker says 12.1mb but its a completely different gas valve.
Im stumped on this one.... im just to unsure to start adjusting when the minimum and max value is that far out. Is there a reason someone would adjust it that way?
Any help would be great on this one
Cheers
Mark
