Finally .. after a few partial attempts we have our gas hob working.
We had it fitted by Peter Molony a local certified Gas Installer who fitted the pipework in the kitchen and all the associated regulator, pipes and brackets for the two cylinders outside.
The cooker is made by Steel Cuisine of Italy and is their budget model .. the Party!!

Looking forward to cooking our first bit of food …. just have to decide what it will be.
