Hi fishnwich,
Welcome to the Heartland Owners Forum and Family. We have a great bunch of people here with lots of information and all willing to share their knowledge if needed.
I did a little search and found this place that looks like you can download a manual, but you do need to know your model number.
Enjoy the forum.
