It is in the low 40s at night so I am starting to burn. I am a newbie and would like to adjust the flue  to the correct temp. What is that and what type/brand of thermometer is going to work best? Jotul 550 in a double sided fireplace. Also would it be effecient to use a fan on the back side to get more heat into the house? Thanks
