As you can see, many burn issues are directly related to your stove’s airflow. If you have reviewed your owner’s manual to make the proper settings adjustments, but you’re still experiencing problems…you might have a leak. Wood pellet stoves operate through a system of air intake and exhaust, and the exhaust fan sucks air out through the burn pot to cause combustion of the pellets. It’s important to inspect your venting setup to see if it’s properly sealed, but it’s more likely the leak is through your door gasket.
It’s simple to test the door seal efficiency with a dollar bill. While holding on to one end of the bill, insert the other side into the door, and shut it. Pull out the dollar while the door is still shut, and note the resistance. You shouldn’t be able to remove the bill without a good amount of resistance. Repeat this method all around your door to check the full effectiveness of your gasket.
