INSPECTING THE CATALYSTS AND REMOVING/REPLACING THE BAFFLE

1. Examine the catalysts to make sure they are in the correct position (if they look crooked push them gently to re-seat them).
2. Use a flashlight to check for ash buildup on the face of the combustors.
3. Use a small vacuum nozzle or soft bristled brush to remove any accumulated ash or soot on the face of the catalyst.
4. Do not vacuum or brush the blanket surrounding the combustor.
5. Inspect the catalyst for any unusual warping, corrosion, or plugged openings.
6. If any unusual conditions are found, remove the catalyst blocks – See replacing the catalysts

Removing/Replacing the Rear Baffle for Inspection 

1. With front baffle segments removed lift front baffle support at front edge and pull toward front of stove.
2. With back end clear, lower baffle support into fire box and remove from stove.
3. While holding up rear baffles with one hand pull rear baffle support toward front and set aside.
4. Lower rear baffle segments and pull to remove.
5. Reverse procedure to replace, being sure to keep baffle segments tight together

 DO NOT OPERATE UNIT WITH OUT CATALYSTS. Only remove the catalysts if required. In general, the less you handle the catalysts, the better. If any unusual conditions are found, remove the catalyst blocks

1. Allow the stove and ashes to fully cool. 
2. Follow the procedures from “INSPECTING THE CATALYSTS AND REMOVING/REPLACING THE FRONT BAFFLE” to gain access to the catalysts.
3. Inspect the catalysts for visible damage or fly ash.  If fly ash exists, gently brush the catalyst off with a narrow soft-bristle brush, or vacuum with a crevice tool.
4. If excessive fly ash exists, or if there is suspected catalyst performance issues, fully remove the catalysts by gently pulling the catalysts outwards towards the front of the stove. It may be necessaryto gently rock the catalysts from side to side and top to bottom while pulling outwards to free the catalysts from the opening. Avoid dragging catalyst over bolts.
5. Remove any remaining gasket material from the opening and from the catalysts. 
6. Inspect the catalysts for any fly ash or clogging, and remove with a soft bristled brush or vacuum crevice tool.  If extra cleaning is needed, follow the guidelines below: -You may use compressed air under 35 psi, air only, no chemicals. -You may soak the catalysts in a hot water mix (not boiling), 4 parts water, 1 part vinegar. Rinse with cold water until vinegar smell is mostly gone. -No metal tools such as gun cleaners should be used.  -No detergents or chemicals.
7. Some warping or bowing of the catalysts over time is acceptable, as long as the catalyst gasket continues to seal.
8. Re-install ceramic wool gasket material on the catalysts. Keep the gasket material flush with one side of the catalyst. Masking tape can be used to hold the gasket in place on the catalyst. It will burn away when the stove gets hot. Wrap the tape around the gasket and catalyst so it is reasonably tight and some of the tape side is hanging over the edge of the catalyst, all around. Fold the edges of the tape in over the catalyst face. Finally add 3 smaller strips of tape as shown in Figure 18on the next page.
9. Once the gasket is installed on the catalysts, gently push the catalyst into the catalyst opening until the catalyst hits against the back wall of the cavity. Take care to ensure the gasket is not damaged.
