I'm curios how the airwash works on the Englander EP25. I really don't see any holes coming out of the forward end of the cradle. Other posts have said to block off the airwash to allow more air to the burnpot .All I see is the thin metal lip before the door. There's really nothing to block off unless they mean the holes on the forward end os the burnpot. My curiosity is piqued.
