Empire Comfort Systems fbb4 Variable Speed Blower Kit

Product Description

The EMPIRE COMFORT SYSTEMS fbb4 is a variable speed blower kit designed to improve heat distribution from gas fireplace fireboxes. The kit includes the SVC1 variable speed control and a thermostat temperature sensor, allowing the blower to ramp up and down automatically based on firebox temperature. A power cord and mounting bracket are also included in the package. The fbb4 is an OEM-spec assembly intended for installation by an HVAC technician or qualified fireplace service professional working on Empire and related brand fireplace systems.

The fbb4 is compatible with several universal fireboxes across the Empire Comfort Systems family of brands, including American Hearth, Vantage Hearth, and White Mountain Hearth product lines. It is suited for residential fireplace applications where the existing firebox lacks a blower or requires a factory-replacement blower assembly. Some assembly is required prior to installation; manufacturer installation instructions should be consulted before beginning the job.
