The Empire SD6DFA25 25' Flex Vent Kit is the required flex-vent component used to complete compatible Empire HMFA Forced Air Heat Management System installations. The kit provides the flexible ducting and clamps needed to connect the forced-air heat management components according to Empire installation requirements.
The SD6DFA25 includes 25 feet of flex vent and two band clamps. Empire specifies this kit separately from the HMFA External Forced Air Heat Management System, so both products must be ordered when completing an applicable HMFA installation.
