Hob continued continued continued (3)

The technician who came today to fix the gas connection between bottle and hob said: "A hose, in the house? No es permitido". Not allowed, in Spanish. It must be made of copper, all the way to the hob if there is an oven underneath. And it needs an accessible gas tap. He'll come back tomorrow. Another lean day today. 

About the not possible opening he said: ah, I think we need to shorten the pipe-like thing. Ehhh. I want the correct manual, please.

But it's fixed. P. saw that the gasket (blue in the picture) was in the way, because the burner had been disassembled yesterday, and the gasket was deplaced a bit. That is now positioned correctly, and the 11 mm distance is possible. 13 mm, too.

Lucky we're two engineers, although one is more theoretical.
