8. Grates

8.1Grate 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 through 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-Lever - 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!
