FAN IN A CAN® CAS-3 COMBUSTION AIR SYSTEM
CAS-3 For Oil Heating Appliances
The Fan-in-a-Can diffuses the outside air into the room near the burner to ensure adequate air for efficient combustion.
The CAS-3 model is designed to provide combustion air for appliances when direct connection to the burner is not possible (when the appliance is located in a confined space). According to NFPA 54 and NFPA 31, an engineered system such as a CAS-3, CAS-4, CAS-6 or CAS-7 may be used to overcome the lack of air in a confined space.
The CAS-3 is designed for use with any oil burning furnace, water heater, or boiler with 120 VAC control systems. It may also be used with more than one appliance. The CAS-3 unit mechanically draws air into a structure and disperses it near the combustion air intake of an appliance. If an optional Vacuum Relief Valve (VRV) is used, the incoming air is tempered before entering the structure’s airspace. Refer to the CAS-3 Instruction Manual for guidance in setting up the CAS-3 system based on the size and length of the connecting ductwork and the input rating of the appliance.
