Questions & Answers

Ask a Question
  • What is the rough opening for a fully recessed application Is the 341/2 width including the trim

    The rough opening for a fully recessed installation is 33" W x 18-1/2" H x 7-1/2" D.  The width of the trim is technically 34.1 In.  Thanks for your question!

  • Can the heater be disconnected? ( 34" Prism)

    The heater shouldn't be disconnected.  But each function is independent of each other, so you can have full operation of the fireplace without ever running the heater.  Also, there is a lockout function, by holding down the heat and thermostat down button together, the heater will be disabled until the same buttons are held down together again.  Thanks for your question!
