Empire Hearth Auto Variable Speed Twin Blower FBB20

Empire FBB20 Blower kit

FBB20 is the manufacturer-listed blower kit for DVLL36BP and DVLL48BP Boulevard direct-vent fireplaces.

Exact manufacturer application

Selection and installation

This optional kit circulates room air through the compatible fireplace. The manual identifies two 35727 single blower assemblies and an R12390 wire harness. It recommends installing the blowers through the rear access panel before placing the fireplace in its framed location because access is easier at that stage.

Follow the documented wire routing and retention clips, keep wiring clear of the blower wheels, and reinstall the access cover. Disconnect electrical power before installation or service. The blower does not replace any combustion-air or exhaust-vent requirement.
