I had a similar problem. I wound up putting a barb on the inside of the kettle and running silicone tubing to the coil. Not pretty but it works. I see a lot of installs that don't have that problem.. not sure how people make it fit right. Would live to know as well.
I don't recommend trying to bend the coil.. I did that and have a small kink.. it doesn;t affect the functionality but is a blemish.
