5. Inspect the catalysts for visible damage or fly
ash. If fly ash exists, gently brush the
catalysts off with a narrow soft-bristle brush,
or vacuum with a crevice tool.
6. If fly ash exists, or if there are suspected
catalyst performance issues, fully remove the
catalysts by gently pulling upwards from the
ribs in the cast iron, and then pulling outwards
through the catalyst access opening.
7. Remove any remaining gasket material from
the opening and from the catalysts.
8. 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.
9. Beginning at one corner, re-install fiberglass
gasket material on the catalysts.
10. Wrap the gasket tape around the catalysts so
it is reasonably tight. Double layer the
material on three sides of the individual
catalyst cartridges as shown in the following
picture.

11. Once the gasket is installed on the catalysts,
gently push the catalysts into the catalyst
opening until the catalysts hit against the
bottom wall of the cavity. Take care to ensure
the gasket is not damaged and position the
three cartridges so that the single layer gasket
edges touch one another in the center.
12. Replace the catalyst access door.
13. Heat the stove slowly during your next fire to
allow the fiberglass gasket to properly seat
and seal the catalysts.
