Potterton Promax HE randomly turns off

The orange flame is significant and that alone indicates you need to a Gas Safe engineer.
You have eliminated circulation as the problem, external controls seem in order.Someone familiar with Potterton boilers should be your next call.

Right, thanks very much guys - you've been a big help. Very concerned about this now...I've contacted the engineers to see if they can sent a different engineer to get a second set of eyes. For the time being I'll keep the boiler off. I'll also get some carbon monoxide alarms (I know I should already have these).

Is too much air to the boiler something that can actually be fixed?

You need a new engineer.
