3-4. Ash
Some ash, but not more than three inches, on the sides
and bottom of the firebox is necessary for the proper
operation of the outdoor furnace (as shown in Fig.
47). No ash should cover the mixing channel (the area
alongside the secondary air charge tube). Ash acts as
an insulator, keeping the glowing coals in the bottom
of the firebox hot enough to restart the fire. For best
performance and for a clean, efficient burn, a
shallow bed (3 inches or less) of loose coals (without
ash) should be raked back over the mixing channel if
possible.
1. Remove enough ash to keep the combustion air
outlets free of obstruction (see Fig. 47).
