My 2 year old Weber genesis gas grill does not get the pizza oven box hot enough. I got this from my kids for Father's Day this year and tried a pizza but the box just wasn't hot enough. Without the box the grill will heat to 600 degrees with the lid down .
I have removed the flavorizer bars covered the open areas with foil and turned all three burners way up. Can I close my lid part way or remove the oven stands? Any thing else I can try?
