FC2500 Furnace Installation and Operation Manual
9.2 How Reload Button Works The furnace is equipped with a backlit reload button located at the front. To optimize combustion during ignition and reloading, it is necessary to press the reload button. When you press the button, it will flash rapidly three times. Automatically the combustion air supply will be increased to its maximum, thus the ignition of the charge and the recharge will be facilitated. The button indicator light indicates the status of your furnace according to the thermostatic demand and the available heat. See the table below for details of each state. Led button states Meaning Furnace status Light is ON
Maximum energy: The furnace goes to maximum burn rate and attempts to provide maximum heat while maintaining clean and efficient combustion. The fan blows at normal speed.
The thermostat calls for heat and there is heat available in the combustion chamber.
Light is OFF
The furnace is cold. (Does not consider the state of the thermostat)
Low energy: The furnace is cold; it needs to be lit with paper and kindling to provide heat.
Light blinking slowly (1.5 second per blink)
Energy saving: The furnace burns to a minimum burn rate and distributes as little heat as possible through the distribution air ducts to save wood by maintaining clean and efficient combustion. The fan cycles to remove excess heat.
The thermostat does not call for heat and there is heat available in the combustion chamber.
Light blinking quickly (5 blinks per second):
Thermal protection: The furnace control system reduces to minimum the supply of combustion air. If firebox maximum temperature is reached, fan will blow at normal speed. If plenum maximum temperature is reached, fan will blow at maximum speed. DO NOT ADD WOOD
The furnace has reached its maximum temperature.
