Custom Stove Installations offers regular maintenance / cleaning and repair on pellet stoves and inserts. I strongly recommend an annual professional cleaning especially if you burn more than one ton of pellets a year. A professional cleaning includes a thorough cleaning of the stove and vent pipe. Pellet stoves burn their fuel so completely that the ash is very fine and works its way into the fans, motors and exhaust pathways in the stove. I clean all of these areas thoroughly as well as clean the glass and stove body to get your stove looking new again.
