Whenever I run my stove on the highest setting, there's a smell that develops and is almost like a chemical-like smell of something burning off. They did tell me that there would be a smell when I first started it up, but I've put about a ton of pellets through it so far. I only detect the smell when it's running on the highest setting. I haven't run it that high very often, but enough where I'd think it shouldn't be there? I'd equate the smell to be similiar to when you fire up a toaster or toaster oven for the first time and it burns off the residues inside. Any thoughts?
