Flueblocker for 12"X12" Square Chimney Flue - Chimney Sheep Fireplace Draft Stopper Replacement Damper Fireplace Plug - Better Than Inflatable Pillow or Balloon - Save Energy Block Odor & Debris

Q: Can I use this to block a flue and use an electric fireplace which replaced old wood insert?

Yes, you can usually plug the flue with a Flueblocker above an electric insert. Most inserts with a heating funtion vent the heat forward into the room, not up the flue where it would otherwise be wasted.

Q: My opening is 17x17, do you think the 16x16 will be too small?

The Flueblocker labeled 16x16 has actual dims of 18×18. That will work in a 17x17 hole, but you may have to remove the handle after install so the weight doesnt drag it down.

Q: Can this be used with VENTLESS gas logs?

No, nothing can be used with ventless gas logs to safely plug the flue. If you have retrofitted ventless gas logs into a wood fireplace with a chimney, then it is likely you have not calculated well for the heat spill of the ventless gas logs up the face of the mantel. Wood burning fireplaces cast heat very differently that a ventless gas log. Not to get on a soap box here, but google: "dangers of ventless gas logs". You will find your fill of the issues with burning a non vented gas appliance in a closed home. That is part of the reason gas stoves are on the chopping block with appliance manufacturers as well.

Q: I have a 6x6 square flue (woodstove). What would be the best size to get? The 12x12 and trim it to @8x8? Or the 9 inch round and trim it to a square?

To fit a 6x6 square i would buy the 12x12 and trim it to an 8x8. There is extra hemming to accomodate that. If you would prefer us to trim it to size for you, we offer that service free. Reach out right after you buy the 12x12 and request a trim for a 6x6 flue hole. - Jason
