Enervex ASCA for RS and RSHT 009 to 014

The ASCA Steel Chimney Adapter is used to provide support for the installation of an RS or RSHT chimney fan on a round, air-cooled steel chimney. It is mounted at the chimney termination point.  The adapter consists of a square mounting plate to support the fan and a round collar that can slide into the chimney for a tight fit. The outer diameter of the collar is 1/8" smaller than the inner diameter of the chimney. The 5" collar eliminates the need to secure the adapter externally. Features Can be used on most round chimneys Integrated support allows venting of inner walls Easy to install without use of tools
