Here are step-by-step instructions for cleaning your Harman PF100 Pellet Furnace. These instructions are to be used in conjunction with the owner’s manual that came with your furnace. If you have any questions about the procedure please don’t hesitate to call your local authorized dealer. In order to maintain top efficiency it is important to clean and vacuum the inside of the furnace 3 or 4 times per burn season.
