HI,
My york insert has the same scenario. I too thought it was missing a filter or something but have been using that way for 4 years. The pellet stove manufacturers just adapt these components to their stoves and some off the engineering just isn't there. Igniter rods are is a good example of of bad stove engineering. They burn out because they were made to be incased with a tight tolerence in metal not glowing in open air.
