If the heat's not parallel to the board, you'll never get even heat. Moving the nozzle around won't resolve that. The entire device must have uniform heating, so uniform distance and coverage is required.
I think you're obsessing over the alignment and it's a red herring. The surface tension of the molten solder will pull it into place - however you're not getting an even heat distribution. ALL the solder needs to be molten at the same time and then it will pull itself into the correct place. Hot air isn't great for this. You should also use a tiny amount of flux - just a very thin film.
I thought about that and I do believe it's a good advice. My position on this is that it makes no difference other than perhaps the speed of heating. I will perform an experiment to confirm that though. Thank you so much!

Zmień podejście.
Zostaw dolny podgrzewacz a zamiast hot aira zastosuj grzałkę na podczerwień .
Pozdrawiam
that is my plan indeed :)
Raff you would have made a helluva a surgeon.
yeah, I wouldn't mind a surgeon's paycheck for sure :P

yep, the stand is on its way, should have that problem resolved soon :)

I do use a bit of flux but it burns off before the solder is ready to melt.
Do you think I should use IR heater instead of hot air?

Uneven heating? try to remove the heatsinks from the board. There are no shortcuts to success.
