Water vapour from flue

I have an Ariston combi boiler and have noticed that water vapour is continually pouring from the external flue when the boiler is on. This does not appear to happen with other boilers in the street, they have water vapour when they are switched on at first and then it stops whereas mine always has clouds of steam coming from it. Could this be because of the type of boiler or should I get someone in to check it. Thanks

Condensing boiler ? nothing to worry about.
