I just purchased a Virco VII grill. I'm wondering if the heat distribution on the grill works correctly. They have two pieces of stainless over each burner with a large hole in each. The hole is towards the back of the grill. This gives off tremendous heat directly above where the hole is and hardly any heat to the remaining 50% of the grill. My question is this; Does this sound correct, or does this grill have a problem?
