Superior FBK-200
FBK-200 is an optional variable-speed circulation blower listed for Superior VRT3132, VRT3136 and VRT3142 fireboxes. It circulates room air around the firebox; it does not adjust the gas flame, replace the burner controls or change the heater’s rated input.
Configuration and electrical planning
The kit includes its variable-speed wall control (rheostat), which adjusts blower airflow rather than flame intensity. Plan grounded 120 VAC, 60 Hz, single-phase power before the fireplace is enclosed. The blower installs beneath the firebox and moves room air through the appliance’s circulation path. A qualified electrician must verify the correct junction-box/receptacle arrangement and control wiring for the installed appliance revision. Keep the circulation openings clear.
The firebox manual conflicts internally on whether the electrical kit is supplied; confirm the package contents before ordering an additional junction box. Do not assume the blower kit contains every field-wiring component. Installation must follow both the exact firebox manual and the blower instructions, including power disconnection before service.
Verified model compatibility and documentation
The VRT3100 manual explicitly lists this part for the VRT3132WS/F, VRT3136WS/F and VRT3142WS/F family. Other model compatibility must be checked against its own manual. Superior VRT3100 installation and operation manual, Rev D August 2019, optional equipment and accessory tables on pages 12–16.
