There is one other situation that could jam the drum. When burning Corn, Wheat, Rye or
Distillers Grain Pellets the by-product of these fuels is a hard clinker. If the pot jams up on the
Clinker material, the procedure to clear the drum is a little different from the methods listed
earlier.
Remember to first unplug the unit before trying to clear the jam.
The clinker material may be
stuck to the “Divider Fingers” in the drum. This Clinker material is hard and easily breaks up
using a hammer and screw driver to break it in smaller pieces.
Figure 4 shows the Drum outside of the
burnpot for a clearer view. Note the
“Divider Fingers” and the “Center” of the
Drum.
When breaking up a Clinker use caution
not to hit directly on the divider fingers as
this may bend them and cause them to
bind on the “Cutters”. Break the Clinker
up in the area described as the “Center of
Drum”
Figure 4
How to prevent the Clinker from causing the Drum to jam?
The fuels that create Clinkers are approved with Programs 2 through 4 on the Control Board. The
Clinker can be different in consistency based on the different varieties of corn, wheat, rye and
distillers grain pellets that are grown or produced throughout the US. If this seems to be a
problem, simply choose the next program on the Control Board.
For Example: If you are operating in Program 2, simply change to Program 3. This will cause
the Clinker to be smaller and less likely to jam up during the cleaning process.
Helpful Hint -
The Small Hopper used for starting the stove holds enough pellets to
start the unit and run the unit continuously until the main hopper is empty.
When running the unit in SmartStat Mode it will start the unit 6 times before
running out of pellets. Be sure to keep the small hopper filled up when unit is
starting frequently.
Optional Hopper Extension, Part # 80P54093, is available for a larger Hopper
Capacity.
