Use a staged, dry‑wood hierarchy: start with tinder that has <2 % moisture, then add 3‑4 mm kindling, then 8‑12 mm sticks. Keep the stack tight but leave a 10‑cm gap for airflow. Use a thermal sensor to confirm the surface temperature hits 200 °C before adding larger logs. Arrange logs in a “leaning ladder” pattern to expose more surface area to oxygen. Cover the fire with a heat‑retaining dome (metal sheet or fire blanket) once the flame is established to minimize smoke. Back up the whole setup with a secondary spark source—like a magnesium flare—so you never need to toss more wood. That reduces waste and keeps the process efficient.

Dry, tight, moving—no wind. Keep kindling 3‑4 mm, sticks 8‑12 mm. If spark fails, use magnesium flare as backup. Angle dome 45° to vent excess heat. RFI.
