I can only imagine it is. I have just moved into an apartment with an Diplomat Softline ADP0530 oven and noticed the massive heat loss pumping out of the top of the door- jumped on the net, I was so curious. It looks like something is missing, doesn't it?! At least it makes the glass easy to remove :)
My guess is that it has something to do with making air available for the gas flame? I'm used to electric ovens...
You don't know how to set the clock, do you?
