Cheddar Electronic gas control valve instructions
I dig the pile of paperwork, but I couldn't find it. Anyway I found the Clevedon and a piece of Stuart (I guess).
Please find them in the attachment.
Anyway, I have a Clevedon unit (I bought it during the weekend together with a Cheddar Puffin).
I don't want it. If I need any type of steam electronic control I use Denes Design.
