Central heating layout. This should work, right?

Which mode of camray? 3 or classic?

Camray 3

Take you spoke to Worcester?

Yep. Took a while to get through, but got a friendly old boy on the phone.

The instructions should give max working pressure, typically 3 bar

Well FFS. Since speaking to the Worcester guy, I found the actual manual in a bunch of paperwork that the previous owners left when we bought the property. I took the Worcester guy at his word, but your comment made me take a look... Page 8, "Boiler Details", "Max. Boiler working pressure 40psi - 28 meters (92 ft) water head" (2.7 bar). To my layman ears, that very much sounds like it would be fine running as part of a pressurised system...

I'm so short of time at the moment and I've done all of the work for a gravity fed system now, so I'm going to have to leave it as it is. FFS.

Edit: Now I'm thinking ahead for when I do pressurise it (assuming my understanding above is correct), are there any good diagrams/resources out there that are commonly referenced for newbies like me to refer to?

I assume my hot water cylinder (the indirect heating coil, not the tank itself) would be ok to be in that same pressurised system (it's equally as old as the boiler)? It says on the label "MAX. PRIMARY WORKING PRESSURE 3.5 BAR" and "TESTED PRESSURE bat 1.45", so I assume it's fine?
