Didn't realize you had to bolt this one down, good to know. For You Fireview guys this shouldn't be a big deal with the easy access but it's going to be a pain for my top vented Keystone.I did talk to Woodstock and found out this suggestion came from a supplier. One of the Woodstock folks gave it a try and found it works. This is good to know because as rideau found, bathing that long cat of a Progress could be a problem.
The newer cats which are just coming in now are again different and hopefully even better. They also come with their own frame but you will need those two bolts (shipping bolts that held the cat) that came with the stove to bolt this one in. It is very lightweight so this is why you need to bolt it in place.
