Our FB400 and FB500 Kamado kits will work with a Vision Pro C-Series if our Flame Boss® Kamado VC Adapter is also purchased. TO install, open the ignitor door and insert the VC adapter from beneath by inserting the notched tabs on the VC adapter into the gaps between the door hinges.
Here is a link to the VC Adapter on our website:
