Agree with you pixxyco. Manufacturers spec stands good.
Was it a doorset or an upgrade of an existing frame with a new door leaf?
Be impossible to hang a door if you werent able to fine tune things.
I fitted a new frame, door and all. The guy from the council said that no fire check frame manufactured at present when married with a door will meet the councils requirement - you'll have to remachine the frame!
Seems madness, if you can't shave the door to fit, then you'll machine the frame which must be just as bad.
Suprisingly, after posting I dicscovered an email from the council saying they have decided to accept the door as it is, but no other doors are to have any material removed.
What I find even more baffling is that the door manufacturers have tested their doors to ensure they meet the required standard, yet it is the council whom tell you what spec to fit the door to, even if this may invalidate the fire door certification - explain that one!
