How the CAS-3 and CAS-4 work When the thermostat calls for heat, the Fan-in-a-Can® engages and begins drawing air into the structure. When air flow is established, the pressure switch closes. The CAS sends a signal to the appliance, allowing the burner to fire. The Fan-in-a-Can® diffuses the outside air into the room near the burner to ensure adequate air for efficient combustion.
Can be used t replace Tjernlund PAI-1G, PAI-2G, PAI-3, PAI-4
CAS-4 (Gas) This product is designed for use with any natural gas or LP burning furnace, water heater, or boiler with a 24 VAC control system. It may be used with a millivolt powered system with additional hardware. It may also be used with more than one appliance. The CAS 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 Diagrams A and B for guidance in setting up the CAS system based on the size and length of the connecting ductwork and the input rating of the appliance.
