4. Close the Reaction Chamber door and install the wing nut.

3-9. Firebox
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 the section title 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.
NOTE: Be aware that the hotter the fire, the less creosote is deposited, so weekly cleaning
may be necessary in mild weather, even though monthly cleaning may be enough in
coldest months.
