THE CROSSFIRE OPERATION FEATURES Country Flame designed and built the CF04 stove to burn 100% shelled corn. Unlike conventional pellet stoves, the Crossfire was designed to handle large amounts of ash. This means the Crossfire is capable of burning corn or a mix of wood pellets and corn while reducing the possibility of choking the fire from ash residue.
FIGURE 2: CROSSFIRE COMPONENTS SAFETY FEATURES The Crossfire comes standard with a number of advanced safety features; however, to ensure maximum safety install the stove according to all national and local codes and follow all operating and maintenance procedures. The Crossfire requires a fresh air supply to ensure proper combustion. This fresh air is used in the combustion process to achieve thorough burn of all fuel. The Crossfire needs a sealed and properly designed exhaust flue system.
stable operation of the Crossfire. Fortunately, there are simple, reliable, and cost effective power backup solutions available. Today, a homeowner can choose from a variety of power conditioning systems from a number of “big box” retail stores. For example, Home Depot, Circuit City, Best Buy, Wal-Mart, or other stores carry standard power conditioning equipment. Two good quality power conditioning equipment manufacturers are APC and TrippLite.
OPERATING REFERENCE GUIDE CROSSFIRE – FLEX STOVE (SEE FIGURE #3) • DO NOT use any other ignition accelerant other than igniter/burn gel or igniter blocks to start or enhance the fire in the Crossfire stove. • FUEL the only fuel the CF04 stove is designed to burn is #2 shelled Corn (10-12% moisture) or any mix of Corn and Premium Hardwood Pellets. It is highly recommended that the corn be “CLEANED” (free of dust, fines, & any other foreign matter) for optimum stove performance.
The stir rod will be controlled by the control board. This stir rod assists in mixing fuel with air in the burn pot. The stirring action improves the mixing of oxygen and fuel and accelerates the combustion process. As heat settings are changed on the control board, the stir rod speed will automatically be adjusted to more closely match the feed rates of the different heat settings. The stir rod assists in minimizing “clinker” build-up in the burn pot.

OPERATING INSTRUCTIONS (Using self igniter systems, if auto ignition system (optional) has been installed) NOTE: Each time the stove is started, the firepot must be checked for debris and clear air holes. Some fuels will cause the firepot to build up more frequently making it necessary to stir and clean the firepot more often. Do not allow ash to build up underneath the firepot area or in the ash pan as it will block off the air flow to the firepot.
The auger feed rate on each setting is pre-programmed but may be changed if necessary. The “Auger Trim” button will override the programmed feed rates by +/-5% on all heat levels. To override the feed rate press and hold the ‘Auger Trim’ button along with the heat level button arrow up or heat level button arrow down, depending on desired change. NOTE: In case of a power outage or interruption lasting longer than 5 seconds, the “On/Off” button must be pushed and held for app.
OPERATING INSTRUCTIONS (Without using system igniter) NOTE: Each time the stove is started, the firepot should be checked for debris and clear air holes. Some fuels will cause the firepot to build up more frequently making it necessary to stir and clean the firepot more often. Do not allow ash to build up underneath the firepot. Your control panel has three (3) separate modes of operation (switch located on top of board).
The draft and room air blower speed varies directly with the feed rate. The “Draft Trim” button will override the variable fan function +/- 5 volts on all heat levels. To override, press and hold the “Draft Trim” button along with the heat level button arrow up or heat level button arrow down, depending on desired change. The auger feed rate on each setting is pre-programmed but may be changed if necessary. The “Auger Trim” button will override the programmed feed rates by +/-5% on all heat levels.
the pre-set fuel rate setting. After the start up sequence has been established (approx. 12-15 min.) the unit will run at whatever fuel level setting you selected. The number #2 or #3 heat level setting is recommended for the 1st 30-45 minutes. The auger light will flash when the auger is running. On the wood setting the auger will start right away. If on the corn setting there is a (2) minute delay prior to starting. You can hold the auger button down to override the system and manually prime the auger.

• move to that heat setting anytime the thermostat calls for heat. Otherwise, when the thermostat no longer calls for heat, the control board sets the stove to Heat #1. If the operator changes the heat level to 1 while the thermostat is calling for heat, it will become the new Thermostat Heat Level. But because this is the same setting as when the thermostat stops calling for heat, the operator will get no indication that the thermostat is in control of the stove.
INSTALLATION INSTALLATION PREPARATION Country Flame strongly recommends the Crossfire be installed by a certified professional. Improper installation will create long-term operational and maintenance problems that will plague the homeowner until corrected. The first step is to ensure all necessary parts are available to complete a proper installation. Country Flame recommends a homeowner purchase the Crossfire from an authorized dealer who both knows and supports Country Flame product.

CHIMNEY It is extremely important that a Crossfire stove be vented into a non defective, clean, and properly lined chimney. The chimney system must conform to all local building codes. In the event a masonry chimney is not used, a listed factory-built chimney suitable for use with solid fuels should be used. This listed factory-built chimney system must conform to ULC-S629 (Canada) or UL 103HT (United States.
combustion. In all cases, the flue must be relined with a listed liner system, such as HomeSaver Chimney Liner. If your masonry built chimney contains oversized flue tiles it must be relined to ensure proper draft. This means that a new, properly sized liner system must be installed before connection to the Crossfire stove is completed. Again, for 10 feet or less a 3 inch stainless steel liner can be used with the Crossfire. For lengths greater than 10 feet, a 4 inch stainless steel liner is to be used.

Order the necessary replacement screws or glass clips when ordering glass to ensure worn parts are replaced. GLASS-CERAMIC SPECIFICATIONS Manufacturer Window Type Euro Kera Glass-Ceramic, Kera Lite® KERA LITE® glass-ceramic has a thermal endurance far exceeding that of normal tempered glass. KERA LITE® is designed to operate at temperatures ranging from -4000F to +14000F.
In order to thoroughly clean the exhaust chamber, the Crossfire has two cleaning ports that provide access to the exhaust chamber. In order to gain access to these clean-out ports, the hearth plate must be removed from the front of the Crossfire. FIGURE 18 shows the hearth plate removed from the stove. There is one screw, located in the front center of the hearth plate that must be removed before the hearth plate can be lifted up and out of its location.
a period of use can lead to one or both exhaust chambers becoming blocked and thus causing the stove to burn inefficiently. FIGURE 20 shows an x-ray view into the clean-out port of the right side of the Crossfire. This right side clean-out port allows access to the right side exhaust chamber and underneath the exhaust fan itself.

APPENDIX E: COMBUSTION BASICS An understanding of Combustion Basics will assist in resolving problems with a variety of fuels, changing product and environmental conditions during the operational life of a stove. Just exactly what are pellet or corn stove products suppose to do? PROVIDE A CONVENIENT PLACE FOR STORAGE OF FUEL. PROVIDE FOR CONTROLLING IGNITION, FUEL, COMBUSTION AIR PROVIDE CONTROLLING HEAT FROM FIREBOX TO HEAT EXCHANGER. CONTROL SYSTEM TEMPERATURE.
Combustion Temperature: The temperature required to ensure the release of flammable vapors. To sustain combustion, the heat evolved must maintain this temperature to provide a constant supply of vapors. Excess Air: Any air added to the combustion process above the theoretical value defined as 100% efficiency. A combustion system operated exactly at the peak burn efficiency ratio has a high probability that some of the oxygen in the combustion air will not get paired up with the fuel.
The obvious advantage of Corn or wood pellets over conventional chopped wood logs is the consistency of the fuel both from a size and moisture content. Nature has done a great job of making field corn a palletized fuel that can have even more energy than wood pellets. These palletized fuels burn more efficiently than their wood log counterparts. The heat generated in the burn process, once combustion is achieved, sustains the process as more fuel is added.
As a final note, the two basic stages of corn burning are: a) b) Somewhere around 1100o F the corn fuel particles have combined with oxygen molecules and released the majority of the available energy. Some gases will still not have reached ignition temperature and at this critical stage, if too much heat is removed from the combustion chamber, no more fuel will be burnt. All remaining fuel will simply exhaust through the system as unburned material.
