ok so your getting flooding issues try this first hold your fire button while blowing into the unit hard if that doesn't clear it try plowing into the vent this will be where you saw vapor coming from when plowing into the unit if it wont clear disassemble it clean and dry everything. On the removable coil you will see a silicon seal slid over the chimney pipe with the cupped section facing down towards the coil, remove it and turn it over cup side facing up this makes a better seal when the chimney extension sits down over it, reassemble the spring on top of it and the chimney extension section and reassemble the unit. fill it up and
vape it if it has gurgle blow into the vent while holding down the fire button that should take care of it.
