Had to try the new brush out.Used all but 1 pole from an 18' bag.Thought it was longer than that.Saved me from buying another lengthner like i was going to.Not bad for burning at 300 degrees for 90% of the season.Burn at 3/4 closed to fully closed if the fire is on a full bed of coals,if not i may run at 50%.Now that it's single digits i run primary at 50% with temps at 400 to 500.I wonder if i'll ever run the 2ndaries at these store temps.Should i have gone with a smaller stove so it would've burned cleaner and hotter?Stove 400 stove room 90.All fans running.Little chilly 2 rooms away in livingroom.
