Hi Sue
The manual is here:
https://s3-eu-west-1.amazonaws.com/howdens-howden-prod/web_content/media/library/pdf/2087.pdf
(It wont be a clickable link - this site doesnt work that well so you'll have to copy & paste the address into your web browser).
That said, there's precious little info about doors, only at the bottom of Page 24.
Is it the whole door that has come off or just the inner glass?
