The convection blower will cool down surfaces as air blows over them from the fan. You may not see this as dramatically on the face of the stove where you'll need to put the thermometer. It's easy to check. After the stove has come up to temperature, read the temp, then turn off the blower for 30 minutes and read the temp again.
The house layout and size is going to make it hard to heat far areas like the dining room with the insert. I would focus right now on learning to run the stove well. You should be running full loads of medium to large, well seasoned, splits. The temperature on the face of the insert should reach about 600-650ºF. Once the fire is burning well turn down the air as far as possible without completely squelching the flame. Ideally you want a lot of secondary burn and little or just lazy flames at the logs
Ok perfect and helpful/ When I reload, I usually do with 1-2 logs to maintain air temp in the living room and kitchen. Are you saying I should reload 4-5 logs (which is the max space I have) instead and reload less frequently, or less logs and more frequently?
