Replacing the original style inner top requires a complete rebuild of the stove. Once the new style inner top is in place, if you need to replace the insert you can do so by removing only the stove top. Work in a clear, well-lighted area. If possible, work outdoors. If you must work indoors, use a drop cloth and protect the surrounding area. Wear gloves, a dust mask and protective eyewear. Kit Contents: • Inner top casting insert • Inner top insert • Refractory insulator • 2 pieces of Interam gasket • Refer to Figure 7 to identify parts. Tools Required: • Rubber mallet, or standard hammer and a block of wood • 7/16” open-end wrench • 3/8” cold chisel, or old screwdriver • Needle-nose pliers (for later units only) • Wire brush, hand-held or rotary • Stove cement and putty knife. The easiest way to apply cement is from a tube in a caulking gun. Otherwise, use a putty knife to apply cement from tube. • Penetrating oil. Use Marvel Mystery Oil, Liquid Wrench or similar; WD-40 is not strong enough for this work. • Automotive anti-seize compound • Shop Vac with very good filter. Do not use a regular household vacuum on soot - it is fine enough to pass right through most common filters. • Drop clot or tarp Disassembly Procedure 1. Make sure the stove is completely cool before you begin. Remove ashes and dispose of them properly. An empty ashpan is a handy tray for hardware and small parts. 2. Remove the probe thermometer from the stove top. Some units have a small chrome sleeve on the probe shaft; be sure to keep track of this if it is loose. 3. Lift off the front door(s) and the side door. You can remove the doors by wiggling them back and forth, and lifting at the same time. 4. Unfasten and remove the top. (Fig. 1) A bolt at each corner holds the top to the rest of the stove body. There is a gasketed seal between the stove top and the rest of the body. Lift off the stove top and set it aside, upside down. Check the gasket for compression or wear; replace if necessary. Loosen all four(4) Bolts Before Removal Loosen, then remove these boltsST790 Fig. 1 Remove four (4) bolts to release the stove top. 5. Lift out the decorative front brass bar, the refractory insulator and the catalyst. (Figs. 2 and 3) Be careful with the catalyst, as it is fragile. Place the insulator in a sealed plastic bag pending disposal. Check the combustor for major cracking or crumbling. Refer to the stove manual for details on evaluating the catalyst. From this point on, penetrating oil will help to release hardware. Use automotive anti-seize compound when you replace hardware, to ease future repairs. Refractory Insulator Fig. 2 Remove the refractory insulator. 7001208 8/08 Rev. 3 Remove the anchor bolt and nut joining the damper to the damper adjuster; open the damper or reach through the firebox to get at the nut. The rearward bolt in the base of the adjuster is the adjusting bolt; leave it in place. (Fig. 3) Adjusting Bolt Damper Crank Damper Damper Adjuster Steel Tab CatalystAnchor Bolt Steel Tab Damp- er Rod ST792 Fig. 3 Catalyst, damper and associated parts. Remove the two bolts holding the steel tabs which capture the pivoting ends of the damper, and remove the damper. (Fig. 3) Rotate the damper crank forward and flip the damper adjuster upside down. Slide the adjuster to the left end of the crank. (Figs. 4 and 5) Check the steel damper rod where it passes through the left side of the stove. Early style rods have threads where they pass through the left inner side of the stove. Later units have a retaining clip in a groove on the rod, just inside the left outer side. (Fig. 5) For early units: use the stove door handle to turn the damper rod and crank counterclockwise (as you face the left end of the stove), till the rod unthreads from its threaded hole. As you turn the rod and crank through the high point of the arc, you will need to maneuver the adjuster to clear the back plate of the stove. When the threads on the rod clear the threaded hole, remove the rod and lift out the damper and adjuster. Note that the illustrations show the later style of handle, with a permanently-mounted base. (Fig. 4 and 5) Damper Crank Damper Adjuster ST793 Fig. 4 For early units, unthread the damper rod from the damper crank and the inner top’s inner wall. C-Clip Washer ST794 Fig. 5 On later units, remove C-clip from damper rod. For later units: remove the retaining clip from the steel rod. Pull the rod out of the stove, then remove the damper crank and the damper adjuster (Fig. 5) 5. Unfasten the stove front. There are nuts and washers on threaded studs on the insides of the front/ sides joints; sometimes these are above the inner top /front joints. Sometimes they are below this joint (inside the firebox). There are two studs on each side. 6. Break the cement seal around the stove front. From inside the stove, tap outward along the seams between the front and the stove sides, and between the front and the inner top. Use either a rubber mallet or a hamme...
