Where can I get parts for my stove

[45north]

I have an older model blaze knig classic stove that has the metal front door and I would like to get a glass door, or a door with a glass window, the door has two handles at or near the top and the door lays down toward you as you open it. It does not have hinges on the side like the new ones do. . Also the auto thermostat is not working,it is stuck in one position. Is there a place where I can get parts on the net or should I just contact the factory for parts.

thanks for any advice
