These Welded Handle Dampers are very common in masonry fireplaces of solid brick or stone. These are their characteristics:
They have a long rectangular sheet-iron damper frame and matching door.
The face of the damper door has a long straight handle welded right of center. (image 32-1)
The handle swings forward and back to open and close the damper.
All of the damper hardware is welded or bolted, and is not removable.
The damper door is almost straight vertical when closed.
In this particular application you can see through the damper opening (image 232-2). The flue tile terminates a vertical distant of about 2 feet above the damper . This makes it easy to access to the flue tile, since it is within hands reach. However, with the damper opening being almost vertical, it makes it hard to get your hands through the damper. There are both above the damper and below the damper product options for this application.
If you use the fireplace regularly, use the Chimella
32-5: Chimella install options
If you are looking for the easiest product to take in and out of the flue, the Chimella is a good option. But the Chimella’s spring loaded extending handle is only 24″ long. So select an area within 24″ of your reach in the flue tile or smoke chamber to deploy the Chimella canopy. (image 32-3).
If you have a very high flue tile, you can deploy the Chimella into an area in the upper smoke chamber (image 32-5). But you may need to buy a Large Chimella since the smoke chamber area is wider and longer than the flue tile.
Here are the Steps:
You will need a folding carpenters ruler folded into an L shape, or a builders T square to measure the flue tile (image 32-4) or the upper smoke chamber.
The Chimella sizes to fit when opened in the flue, so you don’t have to be exact with your measurements.
It is better to have a Chimella that is too large, than one that it too small in this application.
If the hole you are putting the Chimella in is less than 16″x16″ in width and length then use the Standard Size Chimella.
If the hole is bigger than 16″x16″, but less than 19″x25″, then use the Large Chimella.
It is important to open a Chimella properly when installing, so it gets a tight fit. Here is a Video to see how the Chimella works. Pay close attention the the part of the video about tightening the collar with the purple dot on it.
If you want to plug it and forget it, use the Flueblocker
32-6: Flueblocker cut for handle
Use the Flueblocker if you don’t use your fireplace very much, and you just want a way to plug the flue tightly for a long duration. It seals and insulates very well. You can tuck it in the peaked area below the closed damper. (image 32-6)
Measure the length and depth of the peaked area below the damper door.
Order a Flueblocker that is a a few inches larger in both dimensions.
With the damper closed, press the Flueblocker into the space below the damper.
Cut a slot in the Flueblocker to allow the damper handle to come down thru the pad. (Image 32-6)
