  • Great heater
100% recommend if you are looking into building your own fireplace stand to put the insert in. This one has been such a blessing. Works very great. It’s not loud. Great size. Heats the house in minutes. Looks great. Was very nervous before buying because it is up in price but I’m so glad i took the chance. You won’t be disappointed. ... show more

  • Looks and functions as advertised.
I purchased the Duluth fireplace. It was easy to install. Hook up was easy. I used the propane hookup. What i like is how easy it is to use and the remote features is nice. Their is no high or low setting. Unit is either on or off. That being said it has very real looking flames and does warm up my family room and adjoining rooms quickly. The remote has a thermost built into it and will shutoff at the temp you set it to, and turns itsself back on when temp drops below your setting. The fireplace changed the whole look of our room and everyone that comes over says how nice it looks in the room. I do recomend this fireplace. ... show more

  • Great fireplace for the price.
Great product for the price. Bought the blower motor, sold separately, and that really increased the heat efficiency.

  • Pass on this insert
This only lasted for 2 years and then it burns up, the wiring. You can also smell gas while the fireplace is running and even added a blower motor to help with the smell of the gas. I do not recommend this insert to anyone. Spend your money elsewhere

  • Good boy
I love my fireplace. It truly heats up three rooms in my house. I haven’t learned to operate the remote yet, It controls the heat.

  • Poor quality assurance, decent product
Doors don’t line up with each other and screws to adjust them were stripped when I got it. The allignment is off by 1/2 an inch, looks pretty bad. Other than that good heat output and easy to install

Love my new fireplace I was a little disappointed to find out it did not come with blower.. We had one from our fireplace we replaced so it worked out

  • Yes, the fame height is adjustable.
At first I was disappointed because I couldn't adjust the flame height. I remember reading in the reviews that you could, using the remote. But no, the remote only sets the room temperature. It's not the best, it would be better if you could program in different temps for different times of the day. But then I figured out you CAN adjust the flame height using the on/off/ignite knob. Just push it in and turn while the burners are lit. Over all, I love my new fireplace! ... show more
