If you have any questions on proper operation please
consult your dealer. If it is working fine you do not need
to perform any maintenance. If needed, the catalyst may
be cleaned with compressed air (which does not contain oil)
at no more than 65 pounds per square inch (PSI) pressure.
A shop vacuum blower is the best solution for cleaning the
catalyst. A solution of deionized water can be used to
gently clean the catalyst annually.
Please ensure during any cleaning procedure that you do
not remove any of the coating on the surface of the
catalyst. High pressure and scrubbing of the catalyst will
disable the catalyst. Catalyst replacement is expensive.
Please consult your installer if you have any issues with the
operation of the PCD. Proper operation of your Klear Sky
should require minimal maintenance. If you are having any
issues with a clean catalyst please call Earth Outdoor and
speak with a Service Representative immediately.
Stack
To prevent water from entering your Earth Outdoor
furnace when the furnace is not in use, cover the top of the
stack with a cap or five gallon bucket. When the heating
season begins, be sure to remove the cover from the stack
before using your Earth Outdoor furnace.
Visual Inspection
Perform a visual inspection of the PCD, IBC, and external
cables monthly. Replace, if necessary, any components that
appear to be worn or damaged with parts supplied by the
manufacturer or agent. Please report any damage to your
installer or Earth Outdoor service representative.
