Hi,
I cannot figure out how to install the combustor. My Intrepid model 2115-cat stove did not come with one. Purchased one from Condar, they had a matching size (based on vermont casting part # 30007430) . My manual states to remove the access door, ( I got that part hahah) then it states to remove the inner fireback. After I remove the door there is nothing there to remove. Am I missing a part? How is this accomplished? Thanks.

I have the same stove. You just set the combustor in the slot provided for. There are pictures in the manual. Don't worry about the inner fire back. I don't know why the manual says that but ignor that part. You just remove the access cover which you have done. You will notice a rushing sound when the cat engages. It will engage quickly if you have the three inches of coal specified.

thanks for the reply. The only way I can get it in there to sit is shown in attached pic. Is this how yours is sitting? I am convinced this is NOT right. haha

I got it. The catalyst I have could not fit in the proper position without taking out the inner fireback. There are four bolts that hold the side brick supports. These supports also hold the inner fireback in place. I took out two bolts on one side and was able to slide the inner fireback out of the way. Then I could install the combustor/catalyst. It is a snug fit in the slot given the gasket around the combustor.

Hum, that is not the combuster that came with my stove. It should be a steel cat. I think what you have is installed incorrectly. However the early manual mentions a ceramic cat which is what you have. So maybe you have one of the first ones that had the optional cat that apparently was ceramic. Remember the cat was/is an option at extra cost for the Itrepid FlexBurn. If you need to replace it they will give you the sterling version now. I'll look at my manual from 18' and check on this though.

tommyH, you do have it correct. Within a year they changed it so you don't have to remove the inner fire back and you just set the steel one in there so the honeycomb is vertical. Let us know how yours performs though. Looks like they were quick to figure out for it to be a true flexburn you shouldn't have to take the stove apart to switch between cat and non-cat.
