  • Works great and measurements are accurate
This fit perfectly in my existing mantel box. The product is well built and easier to install than the original. Looks great and functions great. The flame burns clean and strong.

  • Heats great
This heater is awesome. It heats really good and it's very pretty to look at. We let the pros install it and it was a very good price. I would recommend this heater.

  • A DIY project for Natural Gas?
The default setup is for propane. The instructions all say a qualified gas installer should do the work. Download and read the installation instructions before ordering. Installed and working.

  • Bad Smell - Bad Thermostat -flimsy logs
Looked everywhere trying to find the source of a certain smell. Wife said it smelled like burnt plastic, both of us kept smelling a uncomfortable burning smell whenever the flame kicked on for a while. Thought it might just be a new fireplace smell that would go away after some use. We have ran it 4 times now, with same smell. Thermostat is actually just 5 settings numbered 1 to 5. Very hard to actually set a temperature. At the lower settings the fireplace had a high pitch whistle and could be heard on other floors. Lastly and just a small think but the logs fit together by having screw sit in dips. A couple of the screws were wobbly and made it hard to have the logs sit solidly. ... show more
