Combustion AIR Systems (oil)

CAS-1 and CAS-2 (oil)

Direct Connect

The CAS-1 and CAS-2 Field Combustion Air Systems provide controlled amounts of outside air for proper combustion of oil heating appliances. These models were designed specifically for use with Aero, Beckett, Carlin, Riello, or Wayne burners.

HEN TO USE THE CAS SYSTEM:

• Too tight construction

• Provide source of fresh air for combustion

• CAS-1 & CAS-2 connect directly to oil

CAS-3 (oil)

This model is designed to provide combustion air for appliances when direct connecto the burner is not possible. According to NFPA 54 and NFPA 31, an engineered system such as a CAS-3 may be used to overcome the lack of air in a confined space. The CAS-3 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. The CAS-3 is equipped with a two speed control for enhanced versatility.

HOW THE CAS-3

When the thermostat calls for heat, the Fanin-a-Can™ engages and begins drawing outside air into the structure. When air flow is established, the CAS allows the burner to activate. The Fan-in-a-Can™ diffuses the outside air into the room near the burner.
