from hearthstones pdf on linkage replacement for EQ
this has clearly been an issue...
let me know if you need the images as well
The primary air linkage moves through two holes in the bottom of the stove. As the cast parts expand and
contract in response to the heating and cooling of the firebox, the rod may shift very minutely, but enough to
cause it to bind on rare occasions. This may cause the air control to move with difficulty, or become stuck. To
completely eliminate this as a concern, the linkage rod (item 27 in the page one drawing) has been modified.
The exposed portion of the shaft above the connector arm on the top of the linkage has been eliminated. The
linkage now passes through a single hole and will not bind, but still has enough support to stay in place and
function properly.
To replace the linkage, follow these instructions.
1. Remove the ash pan door by first removing the two bolts located under the ash dump with the 7/16â€
wrench.
2. With the ash door removed and set aside, place a couple of boards directly under the ash dump. This
will protect the hearth and allow you to work on the ash dump.
3. Remove the five bolts that hold the ash dump (28) to the bottom of the stove with a 7/16†wrench or
socket. Gently drop the ash dump down onto the boards and pull it out to work on it.
4. Tap out the small roll pin (and retain for reassembly) in the linkage rod (27) so that you can lift out the
linkage rod (27) and the spring (26) and washer (not shown). Place the spring and new linkage rod
back into the ash dump.
5. Before you replace the ash dump, reach up into the bottom and make sure the air shutter plate moves
easily left to right. If you are experiencing any binding, the retaining bar above the plate may be bent in
a restrictive position. This is a light metal piece that you can easily bend up to relieve this pressure.
6. With the washer, spring, and linkage properly installed (remember to tap the roll pin back into the
linkage rod), lift up the ash dump (making sure the pin that extends down from the shutter plate drops
into the slot in the extension on the linkage rod – as shown in the circled portion of the illustration on
page one) and position it so that the bolts can be rethreaded back into the bottom to attach the ash
dump back onto the bottom.
7. Line up the ash door and secure it by turning in the two screws previously removed.
8. Check the primary air control for fit and function.
