Good afternoon, and welcome to the Technical section in JustAnswer, an independent paid question and answer platform that matches customers' questions to experts in various skills. My name is ***** ***** I'll be happy to help you today.

You will need to re-commission the appliance. This needs to be done by a Gas Safe registered engineer, for example whoever last serviced the boiler.

OK. So you'll have to work through the troubleshooting for flame lift.
