We just installed a new to us wood stove. We have no clue on the brand because we can't find any label on it but on google search it looks like an Century brand stove. It has the standard 5-6 inch legs on it with glass in the door. You can't see the flue pipe from inside the stove since there is a steel plate with small holes drilled in it and the smoke seems to travel to the front of the stove before going up to what looks like a open space towards the front of the burn box. We got a temp gauge and followed the directions and placed it on the flue pipe about a foot above the stove. We have tried everything we can to get the temp into the green but it just stays around 200F zone. We have moved the temp gauge to the side of the stove and it's right around 340F for the temp which is in the green. Are we doing something wrong here or is that just how this model is designed?
