combustion temperature and you will have to repeat holding the on-off button once the Harvester system is
allowed to gain additional firebox heat. Upon reaching proper temperature, pressing the on-off button will
cause the thermostat lights to light up and cause the auger light to blink green and flash on and off
corresponding to the feeding of corn fuel into the burn pot.
Based on the heat setting on the control board, the Harvester will automatically turn the stir rod at a
predetermined rate to ensure turbulence and proper mixing of the fuel during the burn process. The stir rod
will ensure that “clinkers” are minimized if not completely eliminated. In addition, the stir rod ensures that
the fuel and flame are constantly agitated within the burn pot so as to ensure proper mixing with combustion
air. The Harvester burn pot has been designed to ensure maximum efficiency of burn while minimizing the
amount of ash being produced while at the same time minimizing the clinkers that can choke out a fire.
Testing by Country Flame has shown that the unit can be operated for several days to up to two weeks
without requiring cleaning depending on the type of fuel being burnt. It should be recognized that
environmental variables as well as the type of fuel can have drastic effects on the amount of ash or clinkers
formed during the burn cycle. Burn pot cleaning will depend upon the quality, quantity, and moisture content
of the fuel. Ash removal will be required from time to time depending on the amount of usage and the heat
desired. The Harvester stove should be shut down and cooled before cleaning or removing the ash pan.
ASH REMOVAL
The Harvester stove has an ash pan located on the underside of the firebox. Access to the Harvester ash pan
is obtained below the ash lip at the bottom front of the stove. The door on the front of the ash box is a locking
handle with a gasket seal. The seal provides an airtight fit and the locking handle ensure the ash door doesn’t
vibrate open. Lift up on the handle and make a ¼ turn to unlock the handle. Once the ash pan cover is pulled
forward, lay the ash pan handle back against the face of the cover. This allows the ash pan cover to be
lowered to the floor allowing easing removal of the ash pan itself.
Always remove ashes after they have been allowed to cool properly. Hot ash is dangerous to both
surrounding areas and occupants and can cause fires or severe burns. Wait until the fire has been out for
several hours before removing the ash pan. After the ash has been allowed to cool, remove the ash pan for
cleaning. Protective gloves should be worn anytime the ash pan is removed. Dump the ash in a proper ash
container and remove to a safe outdoors area. Remember that although the ash may look and feel cool to the
touch, a smoldering ember can start a fire. CAUTION: Care should be used to store any ash in a proper
container with an approved airtight lid. If ash is taken outside, water should be poured over the ash to ensure
no fire flare up can occur.
CONTROL BOARD
In 2001 Country Flame introduced its own control board technology, the “
Intelli-Choice.” This control
board technology was introduced across all Country Flame wood pellets and corn stove product lines. The
Intelli-Choice control board is being used exclusively on Country Flame product. Country Flame developed
its own control board in order to enhance its product offering and provide better support to customers.
Country Flame’s control board technology is defined as an “open system.” Country Flame will seek to
provide the most advanced controls while maintaining the look and feel distributors, dealers, and customers
have come to know and expect. This also means a purchase of today’s Country Flame product will provide
an upgrade path for newer and more advanced technology if the customer chooses to obtain it. Country
Flame is committed to its customer base. That means bringing enhancements that provide more heat and
improved burn efficiency while lowering the cost of operation. Country Flame will strive to make the service
support process easier through systematic troubleshooting procedures and repair events that should allow for
evolving “plug n play” operations. Country Flame’s goal is to ensure a properly trained and certified service
technician can diagnose and repair any stove problem in less than 30 minutes whether the stove is one year or
ten years old. FIGURE 3 depicts control board basic theory and FIGURE 4 provides a brief description of
sensor controls.
