WOW - did yours come with the Glass Lid? I'm sooo jealous, double ovens - I would love!!! Love black appliances or stainless.
Although Andy's link did not come thru - if you Google your make and model I think you will be able to tell that the shields are in the bottom oven.
I would not worry about "miss using" the appliance just because of the shield.
And sorry - I mis-read the dates on the thread, thought the question was from last week.
Blomberg Gas Cooker with Double Oven and Grill – GGN61Z
I think I found Andy's link... clic on the picture to enlarge and you will clearly see the shields on the bottom shelves.
Enjoy your cooker!
