Random loading, white birch, log cabin stacking, top ignition. Cold firebox, cold fuel
Pieces loaded in order of increasing weight. 23431 stacking.
57.9 lbs including 2.0 lbs kindling
Estimated moisture 15%.
Run #5 of a cold firebox test series. Heater fired every 2nd day.
The Testo data was started 15 minutes before the test.
Lowest CO number ever recorded, resulting in a combustion efficiency of 99.21%

Pisla HTT 602 door, 22" wide
