Yes, I have the manual but I'm not legally qualified to tamper with
any part of the gas system.

if it's your own, you may - it's only when you charge someone for your
services that a qualificxation comes into it.

I was told I'm not supposed to move/replace my gas piping (as in the supply line between the meter and the boiler/fire/cooker) in my own house (which I obviously ignored).
