Put a lot of snow in a pot, pack it full, then put it on a stove running at
low or medium.
You might well find condensation forming around the top of the pot. Burnt
fuel makes a lot of water vapour.

If you get a lot of condensation it can collect and fall down onto the
burner. It can temporarily extinguish part of the flame, putting fuel vapour
onto the air. This can be dangerous.
But the worst case here is when the condensate hits the generator tube and
chills it. This can cause liquid fuel to come out of the burner, spraying
everywhere. This is not good.
Even worse is the possibility that it can thermal-shock the tube such that
gunge built up inside the tube is broken loose. This gunge then flies down
the tube to the jet and blocks it - solid. You no longer have a stove.
The above are not theory! It was late in the evening in the middle of a
ski-touring trip when I started cooking, and made this mistake. The jet
ended up blocked, and I could not get it clean. We (my wife and I) had a
cold dinner in the snow that night, and had to do an emergency retreat in
bad weather. It took an industrial detergent and an ultrasonic bath to get
the gunge out of the generator tube and the jet.
