Hi
ive got an issue with an Alpha cb50, it keeps going to lock out when its been running and then needs to relight. if you manually reset it its ok again until next time. If you turn the temperature down and leave it on its fine, it will stay on all day and night. its only got a problem when its had time to cool. National grid are going to change the meter and regulator for another reason although when i spoke to Alpha technical thay told me that the regulator could be a cause. they also said that the gas valve has its own pcb and that could be the cause. Any ideas would be welcome.
 
Could be something as simple as the spark generator, or ignition GP's, get the meter changed 1st though!
