There goes a good question to all gas safe registered plumbers. What is the minimum distance between gas hob and tall cabinet? The HSE Advice Line told me that hob manual will state the minimum distance and this is what should be followed. My hob requires minimum 150mm. Speaking to a few plumbers I've noticed that most of them states that it's 300mm minimum. But they couldn't really refer me to the source of that rule. Anyone could clarify it a little bit?
