flues have a damper, which is used to meter the draft between "all the way closed" (no draft flow) and "all
the way open" (maximum draft flow). While the damper's primary function is to help conserve energy during and after
fires, it's most important job is to reliably stay open (and out of the way) during the fire. If the damper falls
shut during an active fire, there's going to be big smoke in the house! Dampers need periodic adjustment where we make
sure they are sitting square in the frame and are opening and closing correctly.
Most chimneys have a throat damper located right over the firebox. These dampers
are actuated with various ‘poker style’ control handles that usually have several different settings between open
and closed. Many chimneys provide excess draft to the firebox, enabling the user to keep the damper partially closed
during the fire, thereby radiating additional heat out into the room. Every fireplace and chimney
is unique, so it is important that any experimentation with damper positioning be done carefully - it is never advisable
to try to change the damper position during a fire. The handle will be extremely hot and even with a fireproof glove
on, you will be reaching directly over the fire.
Some chimneys have top sealing dampers which, not surprisingly, are mounted on the chimney top. These are usually
more efficient than throat dampers, easier to control and shut more tightly. Some top damper models need to be oiled
periodically in order to open & close fully and smoothly. When upgrading to a top sealing damper, it is essential
that it is sized correctly and installed so that it can open and close without impingement.
If you have any questions regarding your damper, or would like your damper inspected/adjusted,
please let us know. We also do this automatically as a part of any flue cleaning. Being familiar with your damper
and how it works will surely help to enhance your enjoyment this wood burning season!
