Hi! We just installed our first wood stove and today was the first day we’ve run it all day. I’m reading mixed things about the flue and am real confused. It’s all over the internet to never close the flue (is that the same thing as the damper?!) while the fire is going at all and only close it when the ashes are cool to the touch due to carbon monoxide poisoning? But then I thought (and have been doing today) that once it’s blazing you close the flue to make the fire last longer??? Which is it?! I don’t want to do do anything unsafe for my family but I also want the most effective heat for the my wood. Help a newbie?! It’s a drolet escape 1800 btw
