Steve Generally, no less than 2mm is recommended and is usually stated on certification and assessments etc. The reason for this is that any less than 2mm can affect the operation of the door and can affect the intumescent performing correctly in the event of a fire. I hope this helps Paul Sansom ~If you have any more questions don't hesitate to contact me

Vince The closer should have a certificate reference (usually a CF number)and this certificate will state in which locations the door closer can be fitted. For example, CF111 for the Briton 2003 closer states that the closer can be fitted in figure 1 position ( standard position with the body of the closer on the door on the pull face) and figure 61 position ( closer fitted upside down with the body of the closer on the transom on the push face). The door may also have a certificate reference on the top or the side of the door and this will confirm which door closers are permitted with the door. If you have fitted a closer which is certificated, compliant with the certificate of the door and is fitted in accordance with these certificates the installation will be acceptable. If I was you I would get hold of a copy of the certificate by Googling the Certifire certificate number (Certifire CF???), check it is installed correctly and then show this to the council along with the fitting instructions.
