Question re quadra fire 5700

I have just purchased a quadrafire 5700 step top wood stove. I have installed it in my basement. The house is a ranch 1800sf with a large atrium. I figure the heat will flow from the basement and flow up the atruim into the main floor. My question is how much wood can I put in the stove to last all night and then reload and run all day. I load it in the am before work at 6:00A and when I get home at 3:30P the fire is out and looks like it has been out for hours. The stove is about 150 degrees. I have the main air control at about 15-20% open. I hear about these 12-13 hour burns do I need to load more wood. I am new to wood stoves so I didn't know can the wood be higher than the fire brick so I can pack more wood in

I am burning a mix of what I was told to be hardwoods. There seems to be some oak (I think) I am not sure about the rest. The split sizes are some 4"x8"x20" flat splits, 4-6" triangle x 16" splits

What is a safe flue temp, I try to keep it at 400. Is that okay

The flue temp I am refering to is with a internal probe style. I wasn't sure if you want to let the fire run hot, because doesn't that mean your wood is burning to quickly?
When I open up the primary air the flue temp will get to 850-900 easily, I didnt know if that was safe. Especially loading before work or bed and letting it roar

Yes I do keep the start up air closed (pulled out) after 15 min. Today I accidentally let the stove get too hot. It was at a flue temp of 1200. fortunately it is rated at 1200 continuous. That seems to be pushing the envelope to close for me. I loaded the stove this morning pretty much packed and it lasted about 7 hours. When I got home there were still some live coals in the stove, but it still was not hot enough to even ignite kindling. I am not clearly sure of what type of wood I am burning, The guy I bought my first load from said it was all hardwoods. It seems to my knowledge they are. When you you look at the ends of the wood they have a tight grain looking similar to red oak, but I cannot be certain. I do pull the primary air control all the way out , then I push it back in about 3/8"-3/4". I am also trying to figure out the best way to get the warm air from the basement to the main floor. I have a boiler with in floor radiant heat, so I do not have any duct to draw the heat into the cold air return and circulate it that way. It may end up that I need to put a blower in with some duct trunk to circulate the air throughout the house. First I am trying to bet the least invasive as possible. I hope to be able to draw the hot air up through the atrium (one thing hot air will do is rise) and then it will heat the kitchen / living room. My house has a open floor plan so hopefully that helps with air circulation. A coworker has a wood burner in his basement, he has a two story house. his first floor is usually 75 and 2nd floor is a little cooler. He used his furnace to circulate the warm air from the basement with the fan only mode. I think if I use something like that could help, even though I do nolt want to install duct in existing walls for a house I just built.
