CAS-6 AND CAS-7
The Fan-in-a-Drum
air into the mechanical room, boiler room, or furnace location to overcome a
confined space or inadequate air supply. CAS 6 & 7 are dual volt units for oil
or gas applications.
HOW THE CAS-6 AND CAS-7 WORK
®
When the thermostat calls for heat, the Fan-in-a-Drum® 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-Drum® diffuses the outside air into the room near the burner to ensure
adequate air for efficient combustion.
