Thanks to everybody who posted answers to our problem of trying to decide between the F600 and the F500.
We finally decided to go with the F500 for many reasons. The look of the stove, the single door on front, the side door being on the left, the design of the door handles, the stove dealer came out and said the Oslo would do the job, I hated the double doors on the F600 and hated the detachable door handle.
I have done all the break in fires and so far so good. The stove is very easy to light and to operate, I love the single air control, the stove is very easy to load wood into and the firebox is so much larger then the Quadra fire 3100. Even doing the small break in fires this stove puts off much more heat then the convection action of the Quadra fire and keeps putting heat out long after the fire is out. I am so happy to have a true radiant stove once again. I cant wait for it to get cold enough to start burning
