The Accentra Pellet Insert will give you more heat, better temperature control and a level of convenience you won’t find in 

any other pellet burning insert. The Accentra Insert’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 a fireplace hearth for your home that doesn’t require a chimney.  A special zero clearance fireplace kit converts 

the Accentra insert into a fireplace that can be placed in virtually any corner or against any wall of your home.  

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 24 hours a day.  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.  No other pellet insert offers such accurate and trouble free temperature 

control.  The control technology gives you the widest heat output range of any insert on the market making it an ideal choice 

to take the chill off in the spring and fall and to heat your home during the coldest months of the winter.

As with all Harman pellet stoves, maintenance is minimal and cleaning is easy.  The Accentra Insert lets you burn close to 

a ton of pellets before ash removal is needed.  And what is even better, the Harman Insert Track System lets you slide the 

insert out of the fireplace so that it can be cleaned or serviced without having to disconnect the venting system. This innovative 

design is only available on Harman pellet inserts and lets you easily reach key components for cleaning.

Note: This appliance is also approved for 

installation into a shop.
