03/09/2019 · "Seperation of at least 25mm to be provided for domestic pipework up to 35mm. For pipework over 35mm then 50mm separation is required. The separation distance can be reduced if the gas pipe is PVC wrapped or a pane of insulating material is interposed." I'm proposing to run several electrical cables past an existing 22mm copper gas pipe.
10/12/2015 · Current Gas Safe regulations state that a 22mm supply pipe must be fitted from the combi boiler to the meter. It may also have to be upgraded to 28mm and 35mm in sections if the gas line is a particularly long distance, has many bends and turns in the route it takes or services many appliances.
For combi boilers to provide instant heating and hot water on demand, they need a high volume of gas in a short space of time. As a result, Gas Safe regulations now state that gas supply pipes from the meter to a combi boiler must be at least 22mm. Many older boilers were connected to the meter by gas pipes of 15mm in diameter but this was before the rise in popularity of the combi boiler so if a combi is being
The exact distance will depend on the size of your home but, generally, the regulations prevent a boiler flue from being situated within 30-60cm of a window or door. This is to prevent harmful gases from exiting the flue and then re-entering the property through an open door or window.

01/08/1997 · The effects of four potential fire and explosion scenarios involving the boiler and natural gas pipeline were quantified to determine minimum separation distances that would reduce the risks to nearby nuclear facilities. The resulting minimum separation distances are shown in Table ES.1.
