Superior BRT4542 42" Traditional B-Vent Gas Fireplace

BRT4542 Overview

The Superior BRT4542 is a 42-inch traditional B-Vent gas fireplace in the Custom Series. The radiant smooth-faced design features a multidimensional refractory concrete log arrangement with deep glowing ember bed for an exceptionally realistic wood-fire appearance. An aluminized U-tube dual burner delivers up to 40,000 BTU of warm, dancing yellow flames. Standard equipment includes White Herringbone refractory panels, hidden screen pockets that retract into the firebox for a clean look, easy-access flue damper with safety shut-off switch, white brick hearth, and durable textured powder-coat exterior finish.

Choose between four factory configurations: Natural Gas or Liquid Propane fuel, with either Millivolt ignition ($3089, remote-ready - operates during power outages via standing pilot) or Electronic Ignition ($3209, includes battery backup). Optional accessories include the BD42 bi-fold glass door ($336), 3 Outside Air Kit options (AK4 $90, AK4X $56, AK4F $78), and the RCKIT4001 wireless remote ($157). The B-Vent system uses 6-inch locally-sourced B-Vent pipe for vertical chimney installation - venting components are not included. Listed to ANSI Z21.50 and CSA 2.22 standards. Mobile home approved.

Why choose B-Vent? B-Vent gas fireplaces deliver the most realistic wood-fire ambiance of any gas fireplace category - tall yellow dancing flames with deep glowing ember beds. Unlike direct-vent fireplaces (which have sealed glass fronts that compress flame appearance), B-Vent fireplaces have open or screened fronts that allow the flame to develop naturally. Unlike vent-free fireplaces (which release combustion products into the room), B-Vent fireplaces vent atmospherically through the chimney. The trade-off is lower thermal efficiency (B-Vent is approximately 40-50% efficient vs 70-80% for direct-vent and 99.9% for vent-free) - B-Vent prioritizes ambiance over heat output.

B-Vent system requires locally-sourced 6-inch B-Vent pipe. B-Vent fireplaces use a natural-draft chimney system that draws combustion air from inside the home and vents flue gases vertically through the roof. The 6-inch B-Vent pipe, flashing, termination, and installation hardware must be sourced separately from a local supplier (Superior does not include venting components with the fireplace). B-Vent has different code requirements than direct-vent or vent-free systems - consult a qualified hearth professional or your local code authority before installation. NOT compatible with direct-vent systems (different pipe, different combustion air path).
