This pic is of the left side of my encore2550. Can anyone tell me what the hole directly in the middle of the screen is for. It is on the molded cast iron part that runs at a 45 degree angle from the back to the front. The hole is threaded, empty, and points directly upward. The stove is not running so I can't wave the incense stick to leak test it yet.
Thanks for your help in advance.
