would be surprised if theres a burner tbh esp with it being a test/setup event

Are they asking you to identify the type of boiler ie, combi,system,open vent?
If so it's an open vent due to the fact that there is only a flow, gas and return pipe on bottom of boiler
If a combi it would have flow, hot out, gas in, cold in and return in with a pr pipe as well

If system it would have flow, gas in, return, a pr pipe and a mains cold some where near to fill boiler, this isn't always the case as the fill loop could be fitted elsewhere

Is this event a training event

You're right I'm wrong

Old age don't come on it's own
