  • Amazing Heater and Beautiful too!
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

  • DO NOT PURCHASE Duluth Forge FDF300T Dual Fuel Ventless Gas Fireplace-26,000 BTU in Walnut
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

  • Fast Delivery, easy assembly
Color: Chestnut Oak
This is a great vent free fireplace w/a beautiful wood mantle. Really puts out a lot of heat and was delivered FREE to my door in just seven days - well packed and strapped down on a pallet for easy unloading. Assembly instructions were easy to follow (and I'm a 75-yr-old lady) Technician had it hooked up and running in 30 minutes. Have only 1 minor complaint; the snap in 'grill' piece in front of the log set is very lightweight and rattles when you walk by, or would have given it 5 stars. ... show more

  • Pilot will not LIGHT
Color: Apple Spice
Had plumber come out to install the fireplace on friday and the pilot wouldn't light, so he called the gas company and had them check the pressure to my house, it was fine. He returned saturday to finish the job, and everything he could think to try to get the heater to light would not work. Defective product. Then I go to Amazon to see about returns.....HA I have to pay shipping and restocking fees of 15 to 25% and theres no one to help on the weekends. I'm emailing the company as the message said, maybe Amazon need to check into Factory Buy Direct as I read another review that the same problem accured. I should have read(my bad). Well now I have a 869$$ heater that won't work and the price of a plumber also....Should have bought local........ ... show more

  • Puts out a LOT of heat
Color: Antique 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
