Initial Installation of Sand
Types of sand to use
1) Sand that does not contain clay, rocks or organic matter is appropriate. Use a sand that when
packed will not allow air to pass through. Mortar sand, or sand that is used in the redi-mix concrete
business is good. Never use gravel.
2) Model 100 CSS furnaces require approximately 0.18 cubic yards, Model 200 – 0.25 cubic yards, and
Model 400 – 0.38 cubic yards of sand.
Installation
1) Cover the grates with a piece of cardboard.
2) One person enters the rebox.
3) Another person shovels the sand into the rebox while the
person inside packs the sand completely, using a piece of
wood like a 2 x 4 x 10 inches long.
4) Fill the base with sand, level to the top of the grates.
NOTE: NEVER LIGHT A FIRE INSIDE THE FIREBOX UNTIL
THE WATER JACKET IS FULL OF WATER AND SAND HAS
BEEN ADDED TO THE CORRECT LEVEL IN THE BASE.
