The CAS-4MV is for use with 750mV power pile gas appliances. Each is designed for optimum safety and includes a proving device that won’t allow the burner to engage without the Fan-in-a-Can® operating. Multiple units or additional controls are required for multiple appliance installations. Each is equipped with a two speed control for enhanced versatility.
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.
The Fan-in-a-Can, Jr. is designed for gas appliances up to 110,000 BTU/hr input. A 4 intake Air Hood (IAH) is included along with mounting brackets to secure the Fan-in-a-Can, Jr. to a wall. It may be used with a residential water heater with the addition of control kit CK-20 FV/FG.
