Disassembling Instructions and Parts Identication
There are quite a few of the CW-30 stoves still in use out there.
This guide will help you to identify parts and pieces while also providing instruction for replacing
gaskets and/or other various components.
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.

Looking into the top of the rebox, you’ll see the wafe as shown below. Find a bolt or
screw to t the hole size (3/8” thread) and thread it into a hole near the center of the wafe.
This will provide a handle with which to manipulate the wafe. Lift up on the wafe and tilt
it back to drop it down and out.

when handling the combustion package, as it does become brittle after burning.
