I have a halstead finest gold combi when I turn the boiler on the boiler goes into its ignition sequence when it comes to ignite the boiler fires but after the igniter stops the boiler cuts out completely...
Difficult to get too specific without knowing if you have gas or oil. Also, I am going under the assumption you mean the burner shuts down, not the whole heating system. That being said, all heating appliances have whats called a safety curcuit. Each control has the ability to shut down if certain critera are not met. There is a sensor that senses light down the blast tube. If no light is sensed in a predetermined time period, then the sensor cuts power to the burner. This stops delivery of fuel so if it does ignite you wont blow up.
(I suspect that the ignitor and burner shut down simultainously.)
It may be the sensor (cad cell eye) is doing its job, however why is the question. Could be a number of things including the fuel delivery, ignition, improper air adjustment, etc.
No qualified professional should diagnose a problem unless they are in front of the appliance. I recommend you find a licensed qualified heating techician. Hope this helps.
