I just recently bought a pitboss premium combination grill and I am wondering if anyone knows of a suitable conversion kit from propane to NG. I understand that pitboss does not make one and every place I have asked says they can only recommend kits made specifically for each manufacturer. Are there any universal kits? Would another manufacturers kit work? Am I SOL? Just renovated a house and ran Natural gas all the way to the back yard and it would be a huge bummer to do that for nothing!
