To “reset” one of these heaters you should press or slide the control valve to completely the OFF position and leave it for a few minutes, this allows the safety device to reset correctly. Then go through the relighting process as per the instruction plate, if after following the process correctly the pilot continues to go out when the slide or button is released there is a problem with the pilot and or safety device ( thermocouple ) at this point you should in the interests of safety contact a local service person to put the matter right.
