how do I relight my back boiler?

there is two push bottom knobs on the bottom of boiler, one black one grey push the big grey one in hold it in and push the small black one but only hold the grey one in you should see the piolet light if not keep pushing the black knob
when you see the piolet light keep holding he grey one for about 20 secs then release
if the piolet won't say on after a few trys you may need a new thermocouple then you need an engineer.
