Hi, fellas what is the standard size door opening on a shaver 290 im not near my stove and was wondering what it is . Thanks, John

standard is 18"x18", I upgraded to the large door (24 1/4" x 21 1/4")

Maybe things have changed but last year when I ordered my 290 I asked for the larger door option and the lady had no idea what I was talking about. However she was aware that I could add additional ports on the rear of the furnace, which I was also interested in.

There was no option I was aware of, I just saw that they could customize different things so I asked how big they could make the door. They got back to me a few days later after doing some research and told me the dimensions and that it would be $200 more.
