Abstract
The present invention relates to a vacuum apparatus in combination with a stove for burning combustible materials, such as cordwood or wood pellets, comprising a combustion chamber in which the material is burned, a stove housing separate but operatively connected to the combustion chamber, and a vacuum apparatus located in the stove housing. The vacuum apparatus comprised of a motor, a housing, a seal plate, a cover plate, a bag cage, vacuum bag, and a hose is used to remove ash, debris, and other combusted material residue from the combustion chamber, thereby maintaining the stove in a clean condition. A vacuum hose installed in the vacuum apparatus transports the combusted material residue from the combustion chamber and surrounding areas into a vacuum bag in the vacuum apparatus. A method for installing a vacuum is also disclosed.
