  • Amazing Heater and Beautiful too!
Style: Thermostat Control Color: Auburn Cherry
The media could not be loaded. We are very happy with our purchase! This is a beautiful addition to our home but this is also a very good heater. It heated our 1440 square foot home from 60 degrees to 68 degrees in less than an hour! Thats the temperature we like to keep our home. Definitely recommend this heater! It was so easy to build when it arrived too! From unboxing to fully functional was less than an hour! Warm and quiet while running. LOVE it! ... show more

  • Looks great
Style: Remote Control Color: Apple
This thing puts out the heat! I cannot use it for more than a few hours because the area (living room, dining and kitchen) gets up to over 80 degrees. I bought a blower for it - don’t know if it really helps. When my installer put it in, he had to take the fireplace out of the mantel several times. He scratched/gouged the crap out of the mantel because there are some really sharp edges on the bottom on the firebox. Keep that in mind if you buy this item so it doesn’t happen to you. He had a really hard time fixing the scratches/gouges because he couldn’t get stain to adhere. I only used it a few times last season but it came in really handy during a winter storm and power outage. I fired it up this season and have not been able to get the remote to work. Speaking of the remote - you are supposed to set a temperature and the flame goes out until the temp drops down and then it’s supposed to come back on but I wasn’t able to get that to work. Maybe if I read the book? Insert struggling emoji here…lol ... show more

  • DO NOT PURCHASE Duluth Forge FDF300T Dual Fuel Ventless Gas Fireplace-26,000 BTU in Walnut
Style: Thermostat Control Color: Walnut
UPDATE FEBRUARY 12, I contacted the Amazon vender on December 14 and gave them the story. The vendor went to Duluth Forge and fought over this bad product. Finally this week I got a part in the mail that might fix this. I have to pay my plumber to come out and install it (this is his third service call now). The part is clearly labeled “made in China” so their advertising is false. UPDATE DECEMBER 11, After Duluth Forge sending me several Emails asking questions about my fireplace I received this response today: "Hello Donna, You bought your unit under unauthorized seller Budget goods. They would have to assist you." So I say, RUN FROM THIS COMPANY, THEY WILL NOT HONOR THEIR PRODUCT. UPDATE NOVEMBER 20TH, I had this professionally installed (licensed plumber) the first of October. Everything was working, but it was still too warm to use. This week I attempted to light the pilot light to no avail. I called the plumber, he attempted to light it but could not. He could get the flames to ignite, but since the pilot would not light it would auto-shut-off (no heat to the thermocoupler). I tried to call the number for service and support, it gives a recording saying we needed to send an Email. Email has been sent, no response, so NO SUPPORT. This is an expensive fireplace, I purchased it as a back up heating system, it DOES NOT WORK AND THE COMPANY HAS NOT RESPONDED. ORIGINAL REVIEW (5 STAR) This fireplace is beautiful. It fit right in front of my rock wall and compliments my living room. It is not too large or too small. It came in two boxes, one is the wood outer mantle, the directions were easy to understand and all of the materials came in the package. The second box had the fire box and the logs. It was also pretty simple to assemble, I had a bit of trouble with the front vent, but was able to figure it out. I called my plumber and he took my old fireplace out and put this one in in a few hours. I just love it! ... show more

  • Very cheaply preassembled
Style: Remote Control Color: White
Very affordable and instructions were easy to read.... however the pre assemble pieces were glued crooked, lopsided. Looked very cheaply done. The insert works perfectly after install. And it was to much of a hassle to return. So I have to suffer looking at the molded crooked.

  • No means of attaching insert into mantle. Instructions page 6 of owner shows 2 angle irons. .
Style: Thermostat Control Color: Auburn Cherry
The gas company installed the gas lines and checked the system for leaks. The blower install was more difficult than any of the installation. Overall the fireplace works as intended. Attaching the fireplace insert onto the mantle to prevent insert from sliding. The instructions on page 6 shows 2 angle irons for attachment which were not provided. Again the product works well. Thank you. ... show more

  • Puts out a LOT of heat
Style: Thermostat Control Color: White
This fireplace is amazing. Had a bit of trouble getting the top vent piece installed but this fireplace would probably heat a bigger area than listed. We’ve had temps of 9 degrees with a negative wind chill for a week which is unusual for us, and it has heated my 1200 sq ft home to the point I’m sweating and it is not an open floor plan. It has kept the entire house hot only set on 3 on thermostat. It goes to a 5. It’s well worth the money!! ... show more
