FAQ's - Questions & Answers

Ask a Question
  • Can this fireplace be installed in an exterior wall where one side of fireplace will be in living room and the other would be on the outdoor patio?

    No, the BHD4 is not rated for use in an exterior application.  Take a look at the Majestic Twilight II (click here) for a see through fireplace that can be used in an indoor/outdoor situation.  The best part about the Twilight II is that the venting is built into the unit, so you don't need to install a vent system.  Thanks for your question!
