W
ARNING: NEVER put foreign objects in the hopper and NEVER burn trash or unapproved material
in the Harvester. Using improper fuel voids the Country Flame warranty and damage to the stove resulting from foreign objects is not covered by warranty.
W
ARNING: Ensure free and adequate airflow to and around the Harvester. This stove is a combustion
system that requires continuous flow of fresh air for proper operation. Failure to provide an adequate fresh air supply can lead to operational problems such as: negative pressure in the home, poor operation of this or other home combustion appliances, or a host of other issues. Remember that other combustion appliances compete for fresh air in the home. Consult with a professional to ensure positive air flow is provided to the stove during operation.
W
ARNING: The Harvester’s exhaust system works with a negative combustion chamber pressure and a
low positive chimney pressure. It is very important that the stove’s exhaust and chimney system be airtight and properly installed. The chimney joints should be sealed with 500 degrees Fahrenheit (500
O
F or 260 OC) silicone sealant (RTV) and secured with at least (3) sheet metal screws. An improperly installed stove or chimney system is the major cause of a home fire.
W
ARNING: When installed in a mobile home, the Harvester must be grounded to the steel chassis of
the mobile home. In addition, the stove must be bolted to the floor. A mobile home installation of the Harvester should be in accordance with the Manufactured Home and Safety Standard (HUD), CFR 3280, Part 24. Consult the local code authority.
W
ARNING: SOOT AND FLY ASH: The products of combustion will contain small particles of fly
ash. The fly ash will collect in the exhaust venting system and restrict the flow of the flue gases. Incomplete combustion, such as occurs during start-up, shut down, or incorrect operation of the Harvester will lead to soot formation in the exhaust venting system. The exhaust venting system should be inspected at least twice every year to determine if cleaning is necessary.
W
ARNING: ASH REMOVAL: The ash pan is designed to be emptied every day. If the ash pan is not
emptied regularly, ash will build up and restrict the flow of fresh air to the combustion chamber. The ash pan door should not be opened for prolonged periods of time (greater than 3 minutes.) If the ash pan door is opened for long periods of time an unrestricted supply of air can flow into the combustion chamber. This unrestricted air flow can cause
Version 2.0b 3
an over fire condition. The airtight seal of the ash pan door ensures a combustion process per the stove design.
CAUTION: Operate the Harvester with the fuel hopper lid closed at all times. Failure to keep the
hopper lid closed during operation may result in the release of combustion gasses into the home from the hopper under certain conditions. Maintain any hopper seal in good condition and do not overfill the hopper.
CAUTION:
THE HARVESTER IS HOT WHILE IN OPERATION. DO NOT TOUCH. KEEP CHILDREN, CLOTHING, AND FURNITURE AWAY. CONTACT WITH HOT SURFACES MAY CAUSE SEVERE SKIN BURNS
. REFER TO THE SAFETY LABEL FOR INSTRUCTIONS.

INTERNATIONAL ISSUES
Global concerns about climate change, along with rising world oil prices, are creating unprecedented interest in the development of economical and convenient renewable energy fuel burning products. For decades there has been a “grass roots” effort to utilize biomass feedstock as a viable heating fuel. Use of agricultural products such as corn, switch grass, and other annual crops can abate greenhouse gas emissions by increasing carbon storage in the surrounding landscape while displacing fossil fuel use in combustion heating products. Agricultural based pellet fuel is capable of sustained high volume throughput rates that use less energy to produce when compared to the present wood industry. Long term, biomass pellet fuel will become a key part of the global community’s effort to reduce if not reverse the greenhouse effect. This is especially true when emerging third world countries, their growth rates, and their demand for energy is factored into the greenhouse equation.
AMERICA
United States and Canadian stove manufacturers are approaching three decades of providing wood pellet fuel and wood pellet burning products to the hearth industry market. The maturity of this market has ensured a continuous supply of both pellet fuels and pellet appliances while world fossil fuel issues have ensured an ever increasing market demand for more of these products.
These same American and Canadian manufacturers continue to innovate and improve wood pellet products with each passing year. At the same time, an ever increasing demand for the wood fuel puts pressure on both sustaining the volume and the quality of fuel raw materials needed to meet the needs of the fuel market. Transportation costs associated with moving the raw materials to the pellet mill significantly impact the local and regional availability of pellet fuel. Research has proved that there are many agricultural based crops and crop byproducts that can be utilized to fuel biomass heating stove products to meet this ever growing market demand. Demand for biomass burning fuel stoves will grow in the coming years.
COUNTRY FLAME
Country Flame has worked for at least two decades in researching and developing pellet fuel burning stove products. Today, Country Flame offers both freestanding and fireplace-insert model pellet fuel stoves. Country Flame has a dedicated research effort underway to produce advanced pellet stove products capable of burning a wide variety of biomass fuel. In 2002, Country Flame was selected for national recognition for the design and development of its Harvester HR-01 biomass burning fuel stove by the Hearth Industry Association.
The Harvester HR-01 was designed to burn shelled corn and biomass pellet fuel (switchgrass.) At the same time, Country Flame customers claim to have test burnt a wide variety of agricultural products that are available in different locales around the United States.
THE PURCHASE OF A COUNTRY FLAME HARVESTER BIOMASS FUEL STOVE IS A VOTE TO REDUCE AMERICA’S DEPENDENCE ON FOREIGN OIL. THE USE OF A COUNTRY FLAME HARVESTER BIOMASS FUEL STOVE WILL AID IN CURBING THE GREENHOUSE GAS PROBLEM OUR WORLD IS FACING. Country Flame is very proud of this American born, American tested, and American made product. With pride and dedication, Country Flame employees wish you and your family a lifetime of happiness and warmth through the use of this product.

THE HARVESTER OPERATION
FEATURES
Country Flame designed and built the Harvester stove to burn 100% shelled corn. Unlike conventional pellet stoves, the Harvester is capable of handling larger amounts of ash. This means the Harvester can burn corn, wood pellets, switchgrass pellets, and other biomass fuel while not being choked out by ash. Country Flame customers who own the Harvester claim they have successfully burnt a wide variety of different biomass fuels. Although Country Flame is pleased that customers are finding wide success in burning locally available fuels, Country Flame cannot support or warranty the burning of untested fuel or seed corn in the Harvester.
Before beginning to install or operate the Model HR-01 Harvester, please consult with the local building authority to obtain a permit. A certified professional should install this product. Before a homeowner operates this stove, a thorough operational understanding should be obtained from reading and understanding this manual. Failure to adhere to all safety notes and instructions contained herein can impact homeowner insurance, void warranty, and create hazardous situations leading to smoke damage, fire, or even death.
The Model HR-01 was designed as a freestanding model stove. The stove has optional legs or a pedestal base. The legs come in a variety of finishes. Contact Country Flame or one of its local authorized dealers to discuss and select product options. Once installed, the Harvester is remarkably simple and safe to operate. FIGURE 1, shown without legs or pedestal, defines some of the Harvester components. From a relatively small firebox the Harvester generates a very beautiful flame with lots of heat being produced into the room where the unit is installed. Clean certified or AFPI approved fuel is to be loaded into the hopper. A motor turns an auger that delivers fuel to the combustion chamber on a timed basis. Corn, pellets, or a combination of any solid fuels can be fed into the Harvester burn pot.

SAFETY FEATURES
The Harvester comes standard with a number of advanced safety features; however, the first step in ensuring maximum safety is to install the stove properly according to all national and local codes. The Harvester requires a fresh air supply. This fresh air is used in the combustion process to achieve thorough burn of all fuel. The Harvester needs a sealed and properly designed “all fuel” vent system. This vent system will be used to remove combustion gasses from the combustion chamber to outside the home. REMEMBER: one of the leading causes of house fires is due to improper installation or improper operation of a stove product. Proper installation and operation of the Harvester is required to obtain homeowner insurance coverage. And, the Harvester needs a reliable source of electrical power. Without reliable utility power or a means to ensure reliability, the Harvester operation will be problematic.
The second step to safe operation is for the homeowner to thoroughly understand the operating characteristics of the Harvester. More importantly, the operator needs to know how to control each one of the stove’s operations. The Harvester has an electronic control system whose “brain” is constantly monitoring stove operations in order to optimize the fuel efficiency and heat output of this product. The Harvester’s electronic control provides a simple one stop location for the homeowner to control Harvester performance and heat output. In order to ensure the safest operation, the Harvester’s electronic control is constantly monitoring pressure and heat activated switches, and input power to ensure proper operation. Additional features include an enclosed firebox, high temperature ceramic glass, optional thermostatic control, a high temperature wiring harness, making the Harvester an extremely safe stove.
BATTERY BACKUP SYSTEMS
The Country Flame Harvester Model HR-01, like all pellet or biomass fuel stoves, relies on electrical energy (wall power outlet) to properly operate. Without electrical energy or with interruptions to the source of electrical energy, the Harvester stove’s operation will be erratic at best. Is power quality, power reliability, or routine winter storm conditions a cause of power problems in a specific locale? If it is, the homeowner will need to provide backup power to ensure stable operation of the Harvester. Fortunately, there are simple and reliable power backup solutions readily available. Today, a homeowner can choose from a variety of cost effective power conditioning systems from a number of reliable outlets today. For example, Home Depot, Circuit City, Best Buy, WalMart, or many other stores carry standard power conditioning equipment. Two good quality power conditioning equipment manufacturers are APC and TrippLite. Their uninterruptible power supplies (UPS) include the capability to handle power failures, brown outs, power surges, and line noise. These products sell for around $35 to $150. UPS system cost is largely defined by the features included in the system. The amount of time (battery size) the system must operate before recharging occurs directly relates to cost. UPS systems are usually sold by the number of electrical outlets and the volt-amperes (watts) the system is rated to provide. FIGURE 2 provides a description of the major electrical and operational components.
What does the Harvester stove require from a UPS system in order to sustain proper operation during a power outage? To answer that question, the homeowner has to decide how long they want the Harvester to operate in the absence of utility power. At the same time, an inexpensive solution that will handle a large percentage of the issues would cost less than $100. This UPS product will operate a Harvester for close to an hour. This same UPS system should provide an audible, as well as visual alarm, to alert the homeowner to local utility interruptions or power outages. The homeowner can then make the decision to continue to operate the Harvester or shut it down until the local utility restores local power. Further, this UPS system will ensure that minor utility glitches do not cause “nuisance” shutdowns or faults in a Harvester stove. If a homeowner wants specific information concerning the size and quality of a specific battery backup system for their Harvester stove, contact Country Flame or one of its local authorized dealers who will assist in providing a specific solution.

FUEL REQUIREMENTS
The Harvester Model HR-01 was designed to burn multiple types of fuel, including corn, switch grass and wood pellets. Country Flame recommends number 2 yellow shelled corn be used as fuel. This corn’s moisture content should be limited to no more than 14% moisture content. Country Flame recommends corn fuel moisture content be maintained somewhere in the range of 10% to 12%. USING SEED CORN AS
FUEL IS DANGEROUS TO OCCUPANTS AND BURNI NG SEED CORN VOIDS THE COUNTRY FLAME WARRANTY.
If pellet fuel (wood or other solid biomass pellet fuel) is used in the Harvester, Country Flame recommends no more than 8% moisture content. If there are any questions about fuels to be used in the Harvester, please contact a local authorized Country Flame Dealer for assistance.
HARVESTER STARTUP
The first step in preparing the Harvester corn-burning stove is to remove it from its shipping crate. Ensure that all materials packed in the burn chamber have been removed and that the Gold (optional) door and its glass have been cleaned per enclosed instructions included in this manual.
NOTE:
(1) Failure to properly pre-clean the Gold (or any plated) door and the glass before lighting the
first fire could permanently damage either or both of these items.
(2) DO NOT burn seed corn as it is dangerous and voids the Country Flame warranty.
PRIMING
If this is the first time that the Harvester has been burnt or the stove has run out of corn fuel from a previous burn, priming must be completed in order to fill the auger tube with corn fuel. The Harvester prime mode can be entered by holding the on-off button for approximately 30 seconds or until the auger light starts flashing and the temperature lights start climbing from the lowest light to the highest light showing that the system is “filling the auger.” Once corn fuel starts dropping into the burn pot, the system should be shut off. Once priming is completed, the next step is to prepare the Harvester for burning corn.
FIRST FIRE
Country Flame recommends using wood pellets to start the Harvester Corn Stove. Pellets should be added in layers with igniter gel or igniter bricks sandwiched between the pellets inside the burn pot. It is important that the firebox has a hot pellet fire going before corn fuel is fed into the burn pot. This hot pellet fire is required due to the higher combustion temperatures required for corn fuel.
Wood pellets should be layered with igniter fluid at least level with the bottom of the stir pot arm inside the burn pot. Once the wood pellets and igniter material are layered in the burn pot, the on-off switch should be pressed for approximately 5 seconds or until the on-off light turns from red to green. Release the on-off switch once the light changes to green. At this time the red igniter light will be slowly blinking on and off. This blinking light is an indication that it is okay to light the wood pellets that have already been prepared in the burn pot. Once the wood fuel has been ignited, close the Harvester stove door. Monitor the wood pellet fire until a good blaze has been established.
In order to enhance the startup process, you can press both the up and down heat arrows at the same time. Pressing these buttons simultaneously will cause the stir rod to turn. If the stir rod does not turn, the buttons are not being pressed simultaneously or there is a defect in the Harvester stir rod system.
Stirring the wood pellets, by pressing both heat buttons at the same time, will cause the stir rod to turn and will ensure quicker combustion by adding turbulence to the combustion process. Upon obtaining a strong wood pellet fire, hold the on-off button for approximately 5 seconds or until you see the igniter light move from a slow blinking action to a fast blinking action. Once the igniter light blinks rapidly you can let go of the on-off switch. If the igniter light returns to a slow blink, then the Harvester stove has not reached proper

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.

Alternating Current (AC) Input provided by the local power company. This source of energy must provide a 120 Volt input signal with a frequency of 60 Hertz and a maximum branch current capacity of 15 Amperes. If other devices are connected to the branch, interference or over current may cause circuit breaker to trip. The AC fuse should be rated between 6 and 9 amperes. The recommended fuse is a Little Fuse Model _______. Ensures that no blockage of the combustion input or combustion exhaust air occurs. If the vacuum sensor does not operate properly, the Control Board will not allow the stove to operate. Presently, this sensor is a snap disk operating at 110o F +/- 20o F. This sensor ensures proper exhaust temperature has been reached and that a fire is present in the burn pot before the control system begins the burn cycle. Presently, this sensor is a snap disk operating at 110o F +/- 20o F. This sensor ensures that a proper amount of heat is available at the heat exchanger before the room fan is allowed to operate. If the sensor allows the fan to come on to early, the combustion chambers temperature could drop to the point that self-combustion (ignition temperatures) cannot be maintained. Presently, this sensor is a snap disk operating at 250o F +/- 20o F. The purpose of this sensor is to shut the entire system down in the event the firebox causes an overheat condition. The fuel control is a signal provided from the Control Board to the Auger Feed Motor. The Control Board controls the amount of time that the Auger Feed Motor is on and thereby controls the amount of fuel fed to the fire pot. The room air control is a signal provided from the Control Board to the Room Air Fan. The Control Board controls the phase angle and thereby the amount and time an AC voltage is applied to the Room Air Fan. This signal controls the speed of the room air passing over the heat exchanger tubes and the amount of heat delivered to the living space. The combustion air control is a signal provided from the Control Board to the Combustion Fan. The Control Board controls the phase angle and thereby the amount and time an AC voltage is applied to the Combustion Air Fan. This signal controls the speed of the combustion air passing through the burn pot for the different heat settings An AC heating element used to provide initial heat to the pellet combustion process. Once the Control Board senses combustion, the Igniter is shut off to conserve energy usage.
