Eco Heat
I'm on a commercial job installing a 60kw viesmann heat only boiler. We looked at the gas valve that comes with the boiler and it's spring loaded it did have a little pin on the inside which we though wasn't doing anything and looked stuck so we popped it out! Not sure what it does but if any one knows it would be a massive help. Also the spring loaded valve wouldn't open when we was blowing as hard as we could! So Hows it going to open under gas pressure? If any one knows what I mean? HHelp would be appreciated
