We recommend that you check the installation guide and DVD that where delivered with your conservatory.
 
If either of those were missing they are available as follows:

• Installation guides: www.k2conservatories.co.uk/downloads

• Videos : www.k2conservatories.co.uk/build-installation-movies 

Should these not provide you with the answer you are looking for call our Technical support line on 0871 574 7293 (calls cost 10p per minute from BT landlines, other carriers and mobile networks may vary).
Alternatively submit a ticket, attaching photos if appropriate.
