No, the distance between those two is a result of the nozzle+heaterblock moving up and down by turning that ring.
However, looking at your top picture it already looks like you have a decent space there. But, if I look closely it looks like the ring with the holes in it is not resting on top of the bottom metal plate? It's most likely that the set screw that holds the heater and temperature sensor in has jammed a little bit in its guide hole. The easiest way to fix that is to remove the fan shroud and then grab the nozzle+heaterblock and wiggle it a bit and see if it'll drop down into its proper position.
When you re-attach the fan shroud, make sure that it isn't touching the nozzle. You can also make sure that you push it upwards as much as possible to increase the distance from the print plate a tiny extra amount.

Yes your nozzle is sitting way 2 high, Should look like this, and have about 1mm gap on the inside from the heater block to the bottom of the fan shroud![5a33106ad7275_UM2Nozzle.thumb.png.b055dcc813f33467296c2fc420369a5d.png](//content.invisioncic.com/ultimake/monthly_2017_12/5a33106ad7275_UM2Nozzle.thumb.png.b055dcc813f33467296c2fc420369a5d.png)

To correct just go into the advance menu, heat up the nozzle, and turn the hot-end-isolator by sticking a hex-screwdriver into one of the holes and turn it till you have a gap of 1 mm between the hot-end-isolator (the metal thing with holes) and the PTFE (the white plastic thing).

Thanks labern and ultiarjan, will adjust this today back to normal.
I guess this method is only for adjusting the gap between the hot-end-isolator and PTFE? To stick the nozzle properly out I need to disassemble hot-end to get it more outwards?
