Bayliss mark 7 on Elite greenhouse

I am going to fit some Bayliss Mark 7s auto-vents to my greenhouse (Elite) this weekend, has anybody got any hints and tips or insights into problems I might encounter?

I am not sure if I have deep sill bar or a shallow sill bar anybody know or know how I can tell?

I need to make sure they are fitted properly as I live in a very windy area.

Peter,
Did you fit these? If so, how did you go on? I am interested in fitting one to my greenhouse.

 

Yes I did fit them and it was a lot easier than I thought, the best tip I can give is to take the glass out of the opening windows. It made the fitting much easier, although you will have to watch that the openers are parralel to the glass before you put it back in as it wont go in if it isnt. Drilling was fairly easy and a dry run without drilling is advisable to get all things square. you will have to decide if you need the small angles to fit to the greenhouse, mine is an Elite and I needed them. They have worked very well I have them at there lowest setting and they open at 15c.
