Im renting a house with a well maintained Garrison 2. I grew up with a wood stove with a sliding air vent on the door and a damper on the flu pipe. This set up does not have a damper on the flu pipe. As far as i can yell, its straight up the flu and out the chimney. I can't seem to keep a fire going when I secure or push closed the doors. Im relying on the stove to keep my fuel heat bills down. Àny advice is well appreciated.
