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).

2. Make sure the area directly in front of and under the
gas ignition burner shield is free of ash.
3. Remove any heavy or solidified ash.
CAUTION
Always wear the appropriate personal protective
gear when cleaning ash from the firebox and the
Reaction Chamber.
4. Disposal of ashes - Ashes should be placed in a
steel container with a tight-fitting lid. The container
of ashes should be placed on a noncombustible
floor or on the ground, well away from combustible
materials, pending final disposal. If the ashes are
disposed of by burial in soil or otherwise locally
dispersed, they should be retained in the closed
container until all cinders have thoroughly cooled.
Other waste shall not be placed in this container.
WARNING
When removing ash, be careful not to spill any
coals or ash outside of the noncombustible
container.
5. Each time ash is cleaned out, inspect the firebox
door seal and/or covers to make sure they are sealing
properly.
6. Every other day (or as needed), use the Wonder Bar
to completely scrape the face of the firebox door
frame where the door seal contacts.
