I ordered the silicone gasket for my Eko 40 and it arrived today. I assumed that you would receive enough gasket for both the top and bottom doors, but I only received enough for the top door...I guess that is what I get for assuming. Anyway, my question is this....is it a "normal" thing to only put this new silicone gasket on the top door only and leave the "stock" gasket on the bottom, or is it advisable to put a silicone gasket on the bottom door as well? Just wondering if I should order another....or call and see why they only send one....
