Boiler GC

[Fabrizio70]

Good morning, I’ve to buy a four terminal for my Worcester boiler. I’ve been asked about my GC number and I’m not able to find it anywhere on the case nor on the instructions manual simply because it hasn’t been given to my when I purchase a refurbished house in March 2022. Is anybody able to tell me where I could find it?
Thanks a lot and have a great day!

What’s a four terminal, or do you mean flue? If you mean the latter, then no gas related advice can be given out on a pubic forum, your gas engineer will be able to obtain the information.
