Im just trying to dig up a reference to this....now due to the small volumes of typical domestic installations we would usually purge by relighting an appliance or using an appropriate fitting.
Obviously UP1/1A are the relevant docs for larger installations but is there actual quoted procedure which states what can and cannot be purged into an internal space . In short what is the cut off point by which you MUST use a purge hose and vent it direct to outside?
