using w/o fire ring void warranty?

ive done some searches and read that no damage will result if i use my large without the fire ring.

my question is if it will void the bge warranty? ive read the owners manual and it did not mention anything about this.

i am considering removing the fire ring, putting the plate setter legs up and adding a 3rd grate. i realize that my lump capacity will be down, but has anyone had any other issues? is this a dumb idea?

if so, i plan on placing the bottom grate on the fire ring and hanging a pizza stone below it. this will also ruduce my lump capacity and ruin a pizza stone. however, it will still use the fire ring. i have seen other peoples set ups and i want to make a 3rd grate level without using a water pan. i hate water pans.

i am aware of the adustable rig and the woo ring. however, i cannot afford these things at this time.

thanks.
