Disassembling Instructions and Parts Identication
There are quite a few of the CW-30 stoves still in use out there.

What better way to learn about a stove than to take it apart and put it back together?

To begin dismantling the stove, remove the Harman Logo plate from the center of the top.
This will expose a nut which secures the cast iron top to the stove.
Using a ½” socket or wrench, loosen and remove the nut. Then lift the top off of the stove.

The under side of the cast iron top is gasketed, mostly to prevent rattles of metal to metal
contact. This is ⅜” low density rope gasket (3-44-00888) attached with gasket cement.
Now you’ll see the inner top, which is held down with (6) ½” nuts and washers. Remove the
nuts and washers to lift the inner top.
