Lincoln SCR
Please read this Addendum along with the Manual that came with the stove before
trying to operate your stove.
The information in this Addendum is intended to give a better explanation of how
the new Revolution Burn System works and should be used along with the
information given in the regular stove manual.

How to adjust the Lincoln SCR for different Fuels?
The Lincoln SCR is approved for 6 fuels. They are Pellets, Cherry Pits, Corn, Wheat, Rye
and Distiller’s Grain pellets. Read pages 34 and 35 for information on choosing the
correct program for the fuel of choice.
They are grouped in 2 categories:
1 – Pellets and Cherry Pits, lower in Moisture Content and easy to ignite.
2 – Corn, Wheat, Rye and Distillers Grain, these fuels are higher in Moisture Content and
therefore more difficult to start.
The Lincoln SCR basically has 2 operating modes:
1 - Manual Mode. In this mode the operator of the Lincoln SCR is involved with starting
the unit, and is available to monitor the start-up process of the Lincoln SCR. This mode
includes the Manual position and the T-Stat thermostat position. Only the ON/OFF
button will start the unit up or shut the unit down.
2 – SmartStat Mode is the Automatic Mode. In this mode the Thermostat controls the
unit. The Lincoln SCR starts as soon as the Thermostat calls for heat. The unit shuts off
only after the unit pilots for 1 hour with out calling for heat. If Operating in the
SmartStat Mode, make sure the Thermostat is not calling for heat when trying to
shut the Lincoln SCR off at the Control Board. Turning the Lincoln SCR off at the
Control Board while the Thermostat is calling for heat, will cause the Control Board
to turn the unit right back on.
During the Break-In period and anytime a switch is made to a different Fuel Category,
such as switching from Pellets or Cherry Pits (which have a lower moisture content and
starts quicker) to burning Corn, Wheat, Rye and Distiller’s Grain (which have a higher
moisture content and start slower), the Lincoln SCR must be set up and adjusted for
proper ignition. This means the Damper, Program, Feed and Draft Trim settings must be
adjusted in such a manner that after the ignition cycle finishes, the unit transitions to the
fuel in the main hopper in a smooth manner without overloading the pot.
How to use T-Stat and SmartStat Mode with the Revolution
Technology. (Read page 33 for more information on using a Thermostat)
SmartStat Mode is to be used when the temperatures are mild. Adjust the Control Board
for mild temperatures. Run the Lincoln SCR on the lower settings on the control board to
prevent the unit from cycling on and off needlessly. If the temperature is 50 degrees
outside, it would make sense to run the Lincoln SCR in SmartStat Mode but with the
Heat Level set on #1.This way the unit puts out less heat and will run longer before
temperatures in the house rise above the Thermostat setting. This also provides a more
even temperature.

When burning Corn, Wheat, Rye and Distiller’s Grain Pellets, the program chosen must
give a smooth ignition and be able to advance to the Heat Level chosen. If the Pot
overloads during ignition, adjust the Feedrate down or switch Programs until these fuels
ignite without overloading the Pot. The units must be adjusted for unattended use.
Do not assume the unit functions correctly in SmartStat mode without first adjusting
the unit. When burning grain there are many variables and the unit must be fine tuned
correctly before using SmartStat Mode.
The adjustments that need to be made are:
1 - Choosing the correct Program for the fuel used. (See pages 34-35 in your manual)
2 - Adjusting the Damper (if needed) (See pages 37-39 in your manual)
3 - Adjusting the Feedrate (if needed) (See point 8 on page 57)
4 - Adjusting the Draft Fan Voltage (if needed) (See point 9 on page 57)
5 - Adjusting the Heat Level to a lower setting (to prevent the Lincoln SCR from
excessive ON/OFF cycling). This will also help in maintaining an even temperature
in the home. (See figure 23 0n page 32) Moving to the next Program will also
produce less heat. (See pages 34-35 in your manual)
If the Revolution pot overloads during the Ignition Phase, simply open the Hopperlid to
stop the Auger Motor in the main hopper. This will temporarily shut off the fuel that is
being fed to the pot until it balances back out.
Use the 5-point list above and make some small adjustments before starting the unit the
next time. Again observe how the unit starts up and repeat this process until you get a
smooth ignition when burning Grains.
The Revolution Pot – How to deal with a jammed pot.
What can cause the pot to get jammed?
a – A foreign object gets stuck in the
Drum as it rotates through. For this
to happen, the object must first make
it through the Auger system in the
hopper. Most likely it would jam the
auger, but is some instances it could
end up in the pot.
b – The Drum rotates while it is full of
unburned fuel. If this happens the
dividers in the drum could get stuck
on the fuel as that section of the pot
rotates through. It jams where the
dividers close the opening where the
Ash and Clinker material exit the
pot.

How to fix the problem if it happens?
If this happens, first unplug the unit and use a vacuum to clean out the fuel or ash in the
pot. To clear a foreign object may require reversing the motor by hand. Figure 1 shows
how to access the area where the Switches and Revolution gearmotor are located.
Figure 2
Keep an eye on the 2 switch
levers shown in figure 2.
They eventually will end up
against the end of the notches
shown in figure 3. Rotating
any further than that will
bend the levers and
potentially damage the
switches.
To clear a jam will usually
only require the drum to be
reversed a small amount for
the object or the fuel to free
up.
Figure 3
Once the jam has been cleared, simply plug the unit back in and the drum will rotate
through and stop in the correct position.

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 is 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.

Correction on page 35 of the Manual.
The set screw used for adjusting the damper has been changed to a longer screw for better
adjustment. The damper has been rotated to resemble the figure in the Addendum. The
damper has been pre-set. Adjustments are to be made according to the fuels listed below.
The factory setting is achieved by
turning the screw in until it stops
and then reversing the screw 5 full
turns.
When switching between fuels it is
best to return the Damper to the
Factory Setting and then proceed to
the setting listed below.
Remember: The Settings listed
below are the starting point for
final adjustments to the damper
and are for reference only. Please
read pages 37 through 40 in your
regular Manual.
Figure 5
Damper setting for Pellets, Cherry Pits & Distiller’s Grain
Use the Factory Setting as the beginning point for final Damper Adjustments.
Damper setting for Corn
Turn the Screw in 1.5 turns from the Factory Setting and make sure the damper blade
rests against the setscrew. (This is reversing the screw a total of 3.5 full turns if the screw
is turned in until it stops)
Damper setting for Wheat & Rye
Turn the Screw in 3 turns from the Factory Setting and make sure the damper blade rests
against the setscrew. (This is reversing the screw a total of 2 full turns if the screw is
turned in until it stops)
Correction on page 12 of the Manual.
Point 5 states the exhaust pipe is 3”, please see the corrected version below.
Point 5 should read:
5. The exhaust pipe on the stove is 4” O.D. to accommodate a pipe adaptor.
