I've just bought one of those new flueless gas fires for the lounge
that apparently does not send any unwelcome fumes in to the room.
Is this true or can a smell (even a faint one) be smelt when fired up?
Do you reckon I counld mount it in a recess, maybe 4" clearance all th way round

Flueless gas fires have a number of restriction on their installation that make the apparent usefulness much less of a deal in practice.
They require a large room [1] with permanent purpose provided ventilation. They use a catalyst to remove/reduce unwanted CO in the flue gasses along with an oxygen depletion sensor.
The main problem is that they are smelly and produce much condensation.
As or the clearances required you will need to consult the manufacturers or get hold of the installation book for a unit.
[1] >40m3 IIRC.*Lots* of condensation, having caravanned much when small, where butane fires where common, along with gas lights and cookers.
They don't/didn't make such a fuss about catalysers and fancy electronics in caravans though, presumably due to the moderate numbers of permanent vents fitted on account of all the gas that was expected to be combusted in a relatively small space. Wonder if that's changed...

Yes. They have electric lights and the LPG heaters and fridges have proper flues to the outside.

Our 1978 caravan has a gas (convection) heater with a sort of inverted 'U' tube design. It draws air in from under the floor up one leg of the tube to burn with LPG, up over the top (with fins on the outside of the tube to warm the inside of the 'van) and back down and out with the flue under the floor. Works a treat!
All the fumes come into the room, obviously. As others have said, they make a great source of condensation, and thus toxic mould etc.
