Model Details

Safety First
Because our inserts were designed to deliver maximum BTUs to provide the best heating solutions for your home, the units will become hot to the touch. Consequently, all Monessen direct vent inserts come standard with a certified safety barrier. The screen barrier affixes to your fireplace and has been approved by a third party testing agency to conform to specific standards designed to prevent injury from hot glass.
Total Signature Command® System
Smart thinking — An included touch screen remote offers 3-step flame height, plus an exclusive Smart Mode® thermostat automatically maintains temperatures to help increase efficiency. Automatic battery backup assures operation even if the power goes out.
Efficient Performance
Living green — With a steady state of 88%, the Harmony insert really delivers when it comes to saving energy. Up to 31,000 BTUs of heat allow you to increase your warmth while using less fuel, so you save on heating costs.
Interior Options
Let’s talk style — The Harmony insert comes with Cottage Clay firebrick and log set or black porcelain and Stone and Fireglass kit for a contemporary twist. (Diamond and Onyx Blend standard. Fireglass kits in additional colors also available.)
Decorative Faces
Put your best face forward — Exterior options make sure your insert suits your style. Glass trim, floating and contemporary faces, and two door types are available in colors from Vintage Iron and Iron Age to Satin Black and Textured Black or Mocha. (Not all faces are available in all colors. See Accessories tab above for more information.)
