Chimney Plugs

The products in this Chimney Plugs section are simple, but the effects for a homeowner can be really important. When you pass your venting installation through a combustible wall, there's a really good chance that you're required by code to use a wall thimble for that pass-through. If your venting setup changes or if you get a new heating appliance, you may be left with a hole in your wall where the vent pipe used to be. That hole can decrease your energy efficiency, leave potentially dangerous materials or edges exposed, and can generally be an eyesore. You can eliminate those problems and get your home back in tip-top shape with the simple addition of the appropriate Chimney Plug for your home.

ASK & ANSWER
By Lynne from Chicago, IL on September 23, 2013
There is a hole in the chimney that the HVAC repairman used as a clean out. He taped up the hole, but I have noticed that the tape is coming loose. Could you tell me if there is a chimney plug that is the appropriate part to cover the hole? Please note that it is 5 inches in diameter. Please let me know what you would recommend. This chimney is used for both the boiler and the hot water heater (I have radiator heat.).

Answer:
Unfortunately, we no longer carry a chimney plug that will fit a 5 inch diameter hole. However, a plug can usually be made fairly easily from a sheet of metal and can be fastened in place with masonry anchors.
