Input Voltage	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
Fuse	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
Vacuum Sensor	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.
Exhaust Temperature Sensor	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.
Room Air Temperature Sensor	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.
Overtemp Sensor	Presently, this sensor is a snap disk operating at 250o F +/- 20o F. The purpose of this sensor
Fuel Control	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
Room Air Control	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
Combustion Air Control	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
Igniter	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.
Thermostat (optional)	A thermostat input is provided on the back of each Country Flame product. The Control
	Board has individual personality modules that allow for stand-alone, semi automatic, or fully
	automatic thermostat operation.
