I have an Empress FS unit and I have had it for a few weeks now. I have burned 5 bags of pellets. When I have it on high I get a smell in the house...it is not overpowering....it's not smoke. It smells like a metal type of smell. I do not smell it on low to medium....only on high. Any ideas???? is it just the new stove smell?? is it the galvanized flu smelling?? I do not smell the smell outside at the exhaust, or in front of the unit where the heat blows out. Thanks.
