Cannot remove nozzle

I've been printing with the same nozzle for nearly a year. I am attempting to change it out, and having no luck. 
I am following the directions -- holding the heatblock with a wrench, and attempting to unscrew the nozzle -- but I cannot get the nozzle to move. It seems like it's stuck to the heatblock. 

I've tried cranking the temperature to 295, with no results so far.

Any ideas would be most appreciated.

Update: used a nut rather than pliers, was finally successful in extracting the nozzle.

RE: Cannot remove nozzle

Go slow and follow the E3D instructions carefully. It is important to leave that < 1mm gap between the nozzle hex and heater block before final tightening. Do the final tightening at 285C and be sure there is still a small gap between the hex and block when done. This will avoid having filament leak out the top over the block and creating a mess! Avoid twisting things, and remember you'll need to re-do your Live-Z calibration any time you make hardware changes that impact the extruder and nozzle. Have fun with it!
