DO NOT REMOVE CATALYST UNLESS YOU ARE REPLACING WITH AN APPROVED KIT.
It is recommended that the catalyst be inspected at the beginning, middle and at the end of each season for
issues or defects such as cracks, crumbling, creosote/soot buildup and peeling of the catalyst coating. Not all
catalyst defects may be visually apparent – please refer to the "TROUBLEHSOOTING" sections of this manual
for further appliance symptoms, causes and corrective actions.
You can get an indication of whether the catalyst is working by comparing the amount of smoke coming out
of the chimney after the catalyst has hit light off temperatures with the by-pass open and the smoke not being
routed through the combustor and then with the by-pass closed and the smoke going through the combustor.
Signifi cantly more smoke will be seen when the exhaust smoke is routed through the bypass when a combus-
tor is working. If this is not the case, refer to the "TROUBLESHOOTING" section regarding catalytic
maintenance.
The life span of the catalyst depends on many factors such as type of wood burned, frequency of appliance
use, maintenance of appliance, etc. However, with proper inspection and maintenance a catalyst should last
between 6 to 10 years.
If replacement of the catalyst is necessary, please refer to the instructions supplied below or the replacement
catalyst kit.
ALWAYS CHECK THE WOOD HEATER HAS BEEN COOLED SUFFICIENTLY BEFORE ATTEMPTING
TO CHANGE ANY COMPONENTS WITHIN THE FIREBOX.
