8. Grates
8.1 Grate System and Contro l s
A. Heavy-Duty Cast Iron Grate
System - The functions of a grate
system are to support the coal and
at the same time provide air flow
t h rough the grates to the coal.
Harman grates have a maximum
amount of air flow to produce an
even burning fire. Another function
is to remove the ash from the
unburned coal by grinding, breaking
or shaking them until the ashes fall
through the grates. Harman grates
provide a variable amount of grind-
ing action controlled by the move-
ment of a long shaker-lever located
on the left side of the stove. Grates
are removable without tools.
B. Burns Three sizes of Anthracite
- You can burn pea, nut or stove
coal with these stoves.
C. Exterior Shaker- L e v e r - For
greater safety (from getting burned)
and greater convenience (no need
for separate tools).
IMPORTANT! WHEN SHAKING IS
COMPLETED, TURN THE SHAK-
ER UNTIL THE GRATES ARE
FLAT AND HORIZONTAL. KEEP
ASH DRAWER EMPTY!
