and open the Reaction Chamber door.
4. To remove ashes from the Reaction Chamber, tip
the refractory end cap back as shown before lifting
it out. Use a hoe to pull the ash to the rear of the
furnace; then use a small shovel to remove all of
the ash and deposits from the Reaction Chamber.
Take care not to damage or move the firebrick, or to
damage or move the temperature sensor.
NOTE: It is extremely important to clean all the
way to the back of the Reaction Chamber. To
make sure ash is being completely removed,
mark the hoe handle when the hoe is positioned
all the way to the back of the Reaction Chamber.
Use the mark as a reference when removing ash.
CAUTION
Take care not to damage or move the temperature
sensor when removing ash.

3-9. Firebox
WARNING
Remove all wood, coals and ash from the firebox.
1. Scrape the top and sides of the firebox and around
the door frame area to remove any deposits; then
inspect the surfaces of the firebox for any signs of
corrosion, paying particular attention to the ash level
and below.
NOTE: When scraping to clean inside the firebox,
be sure to pay particular attention to the corners
and to the seams.
2. If signs of corrosion are present, determine the cause
and correct it as soon as possible. Refer to Corrosion
is Present in the Troubleshooting section.
3. A thin, tar-like creosote layer may form on the firebox
walls and migrate toward the bottom of the firebox
where it could collect into a thicker layer. Normally
this layer will burn up as it collects on the bottom.
If it migrates to the bottom of the firebox and does
not burn up, it must be removed. Do not allow it
to cover or restrict air flow through the combustion
air outlets or bottom of the firebox. If larger, thick,
dry deposits form on the walls in the firebox, they
should be removed with a Wonder Bar or scraper.
