EPLACING THE
C
ATALYST
Refer to the Catalytic combustor warranty on page
35 for additional catalyst replacement information.
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 are
suspected catalyst performance issues, fully
remove the catalysts by gently pulling the
catalysts outwards towards the front of the
stove. It may be necessary to gently rock the
catalysts from side to side and top to bottom
while pulling outwards to free the catalysts
from the opening. Save gasket material for
reinstallation. If gasket material is damaged,
it will need to be replaced (Kit number 90-
58313).
5. Remove any remaining gasket material from
the openings 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.
