I have an Enviro Windsor pellet stove that was letting smoke into the house a few times. I attempted to clean it out and when I put it back together, I noticed that I forgot to put a part back and I am unsure of where it came from. I looked at the parts list and it says that is a barb hose shield but it does not tell me where it goes back. Does anyone know the function of this part or where it goes? I could not find anything online about it anywhere. Thanks!
