Chimney Liners and UL LIstings, Part 4

Part 4 of Chimney Liners and UL Listings employees some tongue in cheek humor. Remember Part 1 that started as "You may be an unlisted system if" reminds me of the "You may be a redneck" lines of the Jeff Foxworthy jokes? If you have missed parts 1 - 3 you can read them by clicking here.

We all see liner installations that would make the honorary Foxworthy "unlisted" hall of fame. So as you read the following keep in mind that we are substituting "unlisted" for "a redneck".

• You might be unlisted if you are a stainless steel liner venting a woodburning a fireplace - bare, without insulation.
• You might be unlisted if you are venting a woodburning system and have no tee.
• You might be unlisted if you are bent through the thimble and attached directly to a free-standing woodstove.
• You might be unlisted if you have dry insulation mix poured around you.
• You might be unlisted if you have no rain cap.
• You might be unlisted if you don't have a top plate to seal out the weather and provide support.
• You might be unlisted if you are kinked at a 180 degree angle (courtesy of the installer).
• You might be unlisted if you get in a fight with the installer or shipper.
• You might be unlisted if you're too small for the fireplace/woodstove you're venting.
• You might be unlisted if squirrels and birds are still welcome on a regular basis via no rain cap.
• You might be unlisted if you are installed in a dirty flue.
• You might be unlisted if you are installed in a chimney that the brother-in-law built.
• You might be unlisted if the chimney sits on wooden supports.
• You might be unlisted if the chimney hangs from the ceiling.
• You might be unlisted if the chimney is missing bricks or mortar joints.
• You might be unlisted if the chimney has a lot of vertical cracks.
• You might be unlisted if the chimney moved and the ground didn't.
• You might be unlisted if the chimney only has three sides.
• You might be unlisted if the installer used duct tape to secure the pipe joints.

 You get the idea. Installing an unlisted system can set you up for a whole lot of problems. And that's no joke.
