Saey 92 won't stay lit when doors are closed...

Any suggetions as to why if I close all the doors on my Saey 92 the fire dies. (just purchased this stove) I have started the fire with wood. I get the wood fire going pretty good for about 20 mins or so. Once I close the doors even with the flu 100% to 75% open the fire dies down to nothing and in 1 hour it's completly done.

I had a coal fire last night for about 2 hours, however once I closed the doors even with the flu open it died.

Any suggestions as to what i'm doing wrong? I just purchased this coal/wood stove. Before this stove I had an old Comfort wood stove. No problems at all with draft or anything. Had it running for 3 1/2 hours on wood no problems before reloading.

Please help
