How to Clean the Harman Accentra 

 

 
Here are step-by-step instructions for cleaning your Harman Accentra 
Pellet Stove.  

Please read through this guide before starting

.  These 

instructions are to be used in conjunction with the 

owner’s manual

 that 

came with your stove. If you have any questions about the procedure 
please don’t hesitate to call your local dealer. 

 

In order to maintain top efficiency it is important to clean and vacuum 
the inside of the stove 3 or 4 times per burn season or once per ton of 
pellets burned (you will know you have burned a ton of pellets when the 
ash pan is full).  The stove is designed to be very easy to clean, it should 
take about an hour to an hour and a half to do a good job. 

 

 
 
thorough 
cleaning is required at the end of each heating season.  

Keep in mind that 

cleaning both your insert and venting system is essential.  Cleaning boosts heat output and keeps 
the stove running at maximum efficiency.  Many Harman dealers offer annual cleaning services 
for their customers.

Be sure the stove is completely out and cool 

(and unplugged from electrical power!). 

 

The stove must be completely out before cleaning.  Every part must be cool to  
the touch, including the pellets that are left in the burn pot.  

Live pellets are a  

fire hazard – especially if they get sucked into a vacuum cleaner.  

Every year  

there are stories of house vacuums catching fire by inadvertently sucking up hot  
ashes.  

Worse still this can be the source of a house fire!

 

 
Hot ashes should be stored in a metal container with a tight fitting lid.  When the  
ashes are completely out they can be used as a soil conditioner for your lawn or  
garden. 

 

 
Wear a dust mask! 

This is important!  Don’t be foolhardy when it comes to  

protecting your lungs (Fig. 1).

 

Wear a mask and protective goggles.  Professional  

chimney sweeps wear both while performing cleaning tasks.
