jetmech said:FWIW i just replaced some cracked fire bricks in rear of my T5 and recemented door gasket at upper left corner, while at it i plugged the dime sized hole with foil and am going to see if it makes any difference in burn times and fire control.. i love my stove and can get 9 hours burns with some coals left but would like a little more control of flue temps usually at 2 hrs into a full load my flue can read 450 to 480 with dry oak in stove.. we will see what happens.
I think your flue temps are just fine in fact just about perfect.. I get those temps when the secondaries are really going well and see nothing wrong with that..
