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 the 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.

*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.
