    5.2.4.2 Air and gas supply to the mixture circuit<\/h1>\n

    The presence of fuel gas\/air mixture in the pipework supplying either fuel gas or air to the mixing device, whether due to reverse flow of the mixture, ingress to either feed or to internal leakage, shall be prevented.<\/p>\n

    If a non-return valve is used for this purpose and if it is not resistant to flashback, then an additional high gas pressure switch located downstream of this non-return valve shall be incorporated to shut off the flow of fuel gas to the equipment by means of the relevant automatic shut-off valves specified in 5.2.2.3 in the event of a flame flashback.<\/p>\n

    A flash-back shall trigger an alarm. The required measures after a flash-back shall be described in the instruction for use.<\/p>\n
