Overview

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 unti 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.
