For first break in fire up I only placed 3-4 pieces of wood (18”l x 2.5”w x 1/4”d) after coal bed started with tender/twigs. Noticed some temporary warping of top, front door, and damper which returned to normal after a few minutes. Stove never glowed, didn’t have temperature gauge. Good heat output. Had smoke coming out of air intake which resolved when one section of flex tubing was connected. Easy setup and takedown. A small learning curve to repack everything back in the stove. Overall pleased with purchase. Will update this winter when I use in bell tent for heating/cooking.
