Remove the combustion blower and clean the blades for 16 year old
stoves or perhaps even 3 yrs olds.
Wait until later if the combustion air flow is adequate. Additional
cleaning is not necessary. The blades are probably clean enough if good
clean inside room air is used for combustion air.
If the corn stove is set up or has ever been set up to use outside air
for combustion air, you can believe the fan blades could use a good
cleaning. For a corn stove between 3 yrs old and 16 yrs old, the
combustion blower blades have moved tons of air. The design curve in
the blades may well be smoothed out with dirt, dust, & particulate when
dirty exhaust air got pulled back into the fan blades.
If outside air is used for combustion air, Guess what happened to solid
exhaust particulate that exhausted while cleaning the stove.
Unfortunately, the intake sucked solid carbon exhaust right back into
the intake where the sticky carbon stuff stuck to the fan blades. After
sixteen years of operation, or perhaps even three, some fan blades
could use a good cleaning.
To gain access to the combustion fan, unplug the electrical 110vac
plug. Remove the stove rear and/or side panel. Disconnect the two
electrical connectors. Remove the two retaining nuts to the combustion
For corrosion protection after cleaning the fan blades, shine the
blades with rejectX.
For super quiet operation, lubricate both bearings on the fan motor
Dyke Parker can attest to the benefit of fan blade cleaning. Dyke's
stove is sixteen years old. Dyke produced an attractive utility bill to
enter in the corrosionx contest. Congratulations, Dyke Parket, for a
very good job.
