Was looking into the window of the Fireview last night as I was burning looking up at the cat. I noticed that the metal plate at the Bottom plate at the top of the stove looked warped. This is the plate under the Cat. I looked at the diagram for the stove and this is the called the combustor scoop. I called Woodstock this morning to see if it was a concern and she said that they have changed the material from cast iron to stainless steel. It is a $45 replacement. I asked if I should continue to burn and was told if it is only slightly warped finish the season out and replace this summer. This is only my 3rd season with this stove and the high temperature I have seen on top of the stove is 650. You may want to check out your stove if you have a Fireview, I also noticed they have gone to a stainless steel cat. Woodstock did not seem surprised that this part is warping. They still have great customer service.
