How to Adjust a Pellet Stove Damper

Many people like to burn wood pellets because they are an economical and environmentally friendly source of heat. Most stoves have a damper located on the side of the unit that allows airflow for starting a fire. It is important for homeowners to know how to operate this component in order for the stove to operate at its maximum efficiency.

1. Locate the damper lever on the side of the wood pellet stove. Some models may have a lever that lifts up, while others push back and forth. Determine which way the lever operates by moving it in all directions. Once you are comfortable operating it move it until the damper is about halfway open.

2. Place wood pellets in the center of the grate and then turn the unit on. Allow the pellets to burn for approximately 10 to 15 minutes. Note the temperature of the fire and whether or not the smoke is properly exiting through the stovepipe.

3. If the fire seems to be too hot, you may need to close the damper slightly. This is often noted by a bright red or orange flame. Move the lever a tiny bit in order to bring the grates closer together. Do not close the damper completely while a fire is burning.

4. If the fire is burning very slowly, or if the room is smoky, opening the damper will allow air to get to the wood pellets, while providing an avenue for the smoke to escape. Open the damper just a little farther, and then note the size of the flames. If they still seem to be too small, or if the room is still smoky, open the damper all the way.

5. Close the damper completely when the pellet stove is not in use. Before doing so, make sure to completely extinguish the fire so there will not be any smoke coming out of the stove itself.  Don't forget to remove any hot coals or wood ashes and place them in a metal container in order to prevent them from re-igniting and creating a fire hazard.
