Replacing the Primary Air Cable

1. Remove the throat hood.
2. Remove the right wedge, between the right wear plate and the lower fireback.
3. Remove the right wear plate (bolts at top and bottom, 7/16" heads).
4. Remove the thermostat handle from the thermostat stem with an Allen wrench.
5. Pull the thermostat and stem assembly into the firebox. Be sure to hang onto the
friction spring on the stem.
6. Remove the primary air frame and valve assembly. Pull the frame away from the
stove bottom and to the right gently, to protect the primary air rod.
7. Detach the old cable from both ends. Be sure to keep the small clip that joins the
upper end of the cable to the thermostat.
8. Fish the new cable through the primary air opening at the bottom of the right side of
the firebox and through the primary air frame opening at the back bottom of the stove.
9. Attach both ends of the cable. Be sure the cable hangs properly from the rod on the
thermostat stem, and passes under the stem. Be sure the friction spring is on the
thermostat stem; push the stem through its hole in the stove side and re-attach the
handle with the Allen bolt. Swing the handle back and forth to ensure that there's a
bit of tension on the friction spring. If there's not enough tension on the spring to
hold the thermostat assembly in place when you release it, loosen the Allen bolt on
the handle stem and push the stem further out through the stove side, and re-attach the
handle.
10. Clean the primary air frame and its mating surface of any old stove cement. Bolt the
frame back into position, and test the thermostat action to be sure the valve nearly
closes when the handle is swung fully to the rear.
11. Replace the right wear plate, with the two hex bolts, and replace the wedge that held
the lower fireback in place.
12. Replace throat hood.
