I am new to forum but have had my Whitfield Advantage II Pellet Stove for 4 years. My problem is a smell once the stove gets going. On heat setting 3 or higher it is horrible. The smell only comes out blower holes where heat comes from. It smells like new pipe smell sort of. I cleaned everything including blower motors and checked all pipes for venting leaks. Any ideas or help would be wonderful.
