5. Pry up and remove the left and right wedges. Pull the lower fireback forward and remove

6. If the damper is closed, open it. Use an Allen key wrench to remove the damper handle
stub from the left end of the damper rod.
7. If in place, remove the rear heat shield. Use a 7/16" ratchet socket to remove the four
bolts at the top/back of the stove holding the upper fireback assembly in place.
8. Remove the upper fireback assembly by swinging its right end forward. Watch the left
end to be sure it clears its hole in the left side of the stove. Capture the damper rod
spacer in the left side of the stove and make sure the small washer stays on or with the
damper rod. Removing the right air plate (2 - 7/16 hex head cap screws) may make the
removal of the upper fireback easier.
9. Remove the left and right stainless steel deflectors.
10. Gently slide the entire refractory package straight forward and remove it. Do not lift the
chamber until it has cleared the secondary air probe stick through the back of the
assembly or remove the probe on the back of the stove before sliding the package out.
The chamber is very fragile and must be handled with care.
11. Remove the access panel and the catalytic element from the old refractory package.
Install the catalytic element in the new refractory package and insert new access panel.
12. Reverse the above procedure to complete the installation
