• Accentra Insert

The Harman Accentra 52I Fireplace Insert will give you more heat, better temperature control and a level of convenience you won’t find in other pellet inserts. The Accentra’s many outstanding features make it the best value pellet insert on the market today.

The Accentra’s versatile design lets you convert a heat-wasting fireplace into an efficient heating source. The Accentra Insert could also be used to create a fireplace that doesn’t require a chimney for your home. A special zero clearance fireplace kit converts the Accentra Insert into a fireplace that can be placed in a corner or against any wall of your home. You can choose from a variety of mantels and facings that complement your home’s décor.

The Accentra’s on-board microprocessor constantly senses room temperature and automatically makes adjustments in the feed rate and air supply so you get just the right amount of heat. This remarkable technology lets you fill the hopper, set the desired temperature and walk away. The Accentra Insert lights automatically, brings the room up to the exact temperature and will turn off if no heat is required.

As with all Harman pellet stoves, maintenance is minimal and cleaning is easy. The Insert Track System lets you slide the insert out of the fireplace so that it can be cleaned or serviced.
