Fire door hung too low

[MortarThePoint]

Well I have fitted my first fire door and it's got too big a gap at the top. 🤬

 

Any advice welcome.

 

I only pilot drilled half the holes in the door lining, but I'd like full support really. They're 76mm / 102mm = 3" x 4" hinges (photo below). Is it possible to get these with a different screw hole pattern so that I'm dealing with fresh wood for the screws once I have adjusted the routed slots?

 

Is there an easier solution I'm missing?

Fill in the existing holes (drill them one size bigger then glue in dowels of that size/trimmed down wood, matchsticks, etc)

 

This might not technically be allowed in a fire door (not sure, they are pretty stringent on modifications) but I thought to be a legally valid fire door they had to be installed by a certified person anyway. I'd guess in a simple residential door this isn't an issue and once the door is mounted no-one will see it and I very much doubt the filled hole will make any difference whatsoever in a fire.

Also, make a story stick from a 2x4 (or whatever) so you can avoid a repeat on other doors (and ideally put the hinges in the same place on all of them)

I have a hinge jig, but the slots are a bit larger than the hinge and The hinge positions have conspired against me
