This kit is designed to control more than one appliance on a system using the Field Controls CAS-4 Combustion Air System with a chimney vented gas fired system. The controls in the CAS-4 will operate only one appliance, therefore a CAC-24 is required for each additional appliance to be added to the same CAS-4 unit. One CAS-4 unit can handle at max, a total combined firing rate input of up to 500,000 BTU/Hr. Refer to the instructions included with the CAS-4 for more details and other restrictions.
