I have a VT Encore 2550 stove. During the summer, a child twisted the thermostat handle, located on the right side of the stove, until it was upside down. I removed the inner firewall and flipped it back, bending things as they should be. However, I now have a question. I've only owned it for a year, and this is the first time I've touched it in 9 months. I don't recall if the thermostat lever is supposed to be on or off or if it should have various degrees of open or closed. My current situation is that it's either fully open or fully closed. Is this how it should be?
