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 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 firebox.
3) Another person shovels the sand into the firebox
while the person inside packs the sand
completely, using a piece of wood that is about
2 x 4 x 10 inches long.
4) Fill the base with sand, level to the top of the
grates.
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.
