Recently bought our new to us mo/ho. Had gaslight low fitted by the main dealer. When I tested it out on the, cooker, fridge, and hob had difficulty getting it ignited. I looked and ran my fingers over the cooker burner and was full of soot. So took it back and politely explained that there pdi needs to be reexamine. Any how long and short was told that the gad I have in my new gallon system, does not work properly as when they link a calor bottle its fine.my system has one gallon bottle and space to attach a calor bottle. So my question is lpg all one gas (uk only) I know its changed around in europe, by season. Is it in UK as well, can you get contaminated lpg from suppliers, it certainly smelt like gas when we filled it up, 2 days before we used it. Or is it again maindealer cow poo.
