I have a VC Vigilant and I dont understand how it works. Ive read through many forums and I dont understand the terminology. Every time I run it it eats up wood like crazy. I open the damper when getting the fire going then close it when it gets going. The side teardrop hole stays 90% open. I dont understand what Im supposed to do with the thermostat which I think is the thing in the back with the door that opens and closes itself. I dont know what people mean when they refer to vertical and horizontal mode. The stove was a rusted mess when I got it and I cleaned it out and put sand on the bottom. Im not sure if there are some sort of chambers that could possibly be clogged ? I had a basic woodstove years ago that heated my farmhouse and I had no problem using it, but Im obviously doing alot wrong with this Vigilant. Can someone please explain to me in layman's terms how this stove works?
