The Forced Air Heat Management System (HMFA) is designed to be installed in conjunction with specific Empire Comfort Systems fireplaces to reduce the amount of heat produced during the operation of the fireplace. This system includes a variable-speed, controlled blower that will deliver a desired percentage of the heat produced by the fireplace to the exterior of the building.
NOTE: Flex venting is not included with the HMFA kit. Please order the SD6DFA25 Flex Vent Kit which includes 25' of Flex Vent and (2) band clamps to complete the system installation.
When in operation, the HMFA Forced Air Heat Management System will deliver a percentage of heated air from the fireplace to the exterior of the building. Because a certain amount of air will be removed from the building, it must be replaced with fresh make-up air, to prevent negative pressure from building up inside the structure. Some central furnaces include make-up air dampers. If a make-up air damper is included with the furnace, check the damper for proper function and operation. There are variations in central furnace make-up dampers, therefore, you must check to see if the existing system is compatible. Some systems are designed to operate if a negative pressure is detected inside the building.
Other systems are designed to operate only while the central furnace blower is operating, and would therefore require an additional make-up air damper system to be installed. Make up Air Dampers are available at local HVAC supply stores or contractors. The Make-up Air Damper shall be sized based on the potential amount of cubic air to be expelled. The HMFA system has the potential of expelling 150 CFM. If installing a Make-up Air Damper, it is recommended that it be installed at the opposite end of the building. In addition, installation of the damper at a high level of a vaulted ceiling will help dilute the incoming cold air with the warmer air normally found near the ceiling.
