Advice on air admittance valve. Toilet

[2021bela]

Please see pic! I can't seem to fit this air admittance valve on the back of the toilet. Is there any other fitting I need for this to work.

It’s not really designed for going back there

Why does it have this on the top of the pan connector though!

Yes it has a vent pipe although this is connected to the same soil pipe underneath the floor. See pic below. It was either this or a sani FL w toilet although I was advised against the saniflow because of issues can arise with them.

How would you get it in then. The toilet would still be in the way would it not.

So, the advice would be to get a 32mm elbow and take it away from the toilet a few inches then put the air admittance valve on there. My limited knowledge of these valves I was thinking they had to be on top of the pan connector.
