I'm Gas Safe registered, done CCN1, CPA, CENWAT but not cooker unit.
I've only worked on boilers and other gas heaters, never cookers. It's for a friend, there's a bayonet fitting already there so I'd just be connecting the other one up, carrying out a tightness test then following instructions in book for commissioning.
Am I alright doing this? Also what would you recommend using on threads on hose connector to oven? I don't like gas ptfe as it's leaked a few times when I've used it in the past so I prefer Rocol, would this be enough, should I stick with gas ptfe or use both?
Cheers.
