2×4 dimensional lumber [https://amzn.to/2Rk4qCm]
Pocket screws [https://amzn.to/36V8uzE]
Granite slab
Construction adhesive [https://amzn.to/3a6sqSe]
Wire nuts [https://amzn.to/2TuKEal]

Steps:
1. Start by identifying an insert that’s the closest fit to the opening. Be sure that it is suited for zero clearance and no venting.
2. Fill in the rest of the opening with a fake hearth. Cut to size some 2×4” dimensional lumber and assemble a frame using pocket screws.
3. Secure the frame to the floor with more screws.
4. Cut a hole in the floor behind the frame for the wiring using a spade bit.
5. Shut the power off at the breaker. Fish the wires for the insert through the basement at the panel and through the floor and through the wood frame for the fake hearth.
6. With the wiring pulled through, secure the granite piece to the top of the frame using construction adhesive.
7. Wire the fireplace insert to the wiring coming up through the floor.
8. Secure the insert to the wall on top of the new fake hearth.
9. Turn the power back on.

Resources:
Heath installed an Allure 32 Wall Hanging Electric Fireplace Insert, which is manufactured by Napoleon Fireplaces (https://napoleonfireplaces.com/).

Since Heath was unable to find an insert that perfectly matched the strange dimensions of the opening at the house, he built up a frame for a “fake hearth” to fill in the rest of the hole. For this, he used regular pocket screws and 2×4” lumber, which can be found at any home center. Heath got the granite cutoff from LA Tiles | Marble and Granite Design (https://www.latilesandgranite.com/), though he mentioned that any stone yard would most likely be willing to cut and edge a piece of stone if they were provided with the correct dimensions.

The other tools and materials Heath used to install and connect the electric fireplace insert, including the wiring, fish tape, wire nuts, and screwdriver, can all be found at home centers and electrical supply houses.

  1. I absolutely DO NOT like how that looks. The stained board on the bottom would have looked better if it was white to match the rest of the fireplace. OR, maybe put the insert more at floor level and have the white wood on top.
    But, hey if the home owner is happy that's all that counts. …I guess.

  2. A piece of stone around the bottom, sides and top would have made a much bigger difference, but oh well…what he won't like, is his electric bill !!

  3. The brown piece of wood should be primed and painted bright White. Then put white crown trim in front of that piece around all the edges for a finished look.

  4. This is the funniest yet most awkward TOH video. The homeowner has awful taste, just look at his decorations, his outfit, his haircut, and all his choices (bought the house for the fireplace?). The fireplace itself is god-awful ugly. The logic behind the saving on heat hut using an electric fake fireplace is laughable. And, I don't like making fun of people, but his lisp really brings the whole thing together. The comments are also pure gold.

  5. Everyone throwing some serious shade. Maybe you don't like it, but the video showed how to fit an existing off the shelf fireplace into a larger opening. I think it looks odd but better than how it looked originally.

  6. TOH is one of my favorite vids since Villa days . most of time I consider it as a comedy show . but still like it.I'm a Toronto guy.. we use bricks to build houses here… not a straw and siding..

  7. Fake fireplaces like this are disgusting. The world is becoming artificial, not real anymore. Why not just install a TV in there playing a video loop of a fire? I thought the point of TOH was restore to the beauty of the original?

  8. There are units now that look like just the fireplace logs and go into the existing fireplace. In an old home, I’d want to keep the historic look as much as possible. The digital fire representation shown here is not for me.

  9. I have electric fireplace with remote control. Now I want to use smart plug but have to disconect remote control. Please teach me how to disconect control function. Thanks

  10. I have a square gas fireplace with tile around it. I would like to know if I can make it rectangular that way I have more space avobe for my TV and maybe add a beam or a small mantle? I will also take tile down and update it. House was built in 2005. Will this be too expensive to change opening shape of fireplace?

  11. Very easy to set up and use, attractive but be sure you understand the height–it's not tall. The heat is not overwhelming, but steady and pleasant fireplace fireplace.homes . It's quiet, too. I like the possibility of easily moving it from room to room in the event we want supplemental heat elsewhere. Definitely a good buy.
