Slower start. CO and PM spikes, delayed and smaller than HK-K15.

Air left open, flue damper left open. Data collection stopped at 120 minutes.
Very low efficiency at the end, which reduced overall average to 70.0%, slightly lower than others
This is a reference run to get surface temperature data for a cycle with damper open plus ashbox door open (worst case).
