Specifically designed for a single room application, the Flex Single Sided Fireplace Insert features one open side, enabling the flame to be viewed from the front. The bioethanol, true zero-clearance fireplace can be used to create a striking addition to a feature wall, integrated within cabinetry or a fireplace setting - whether in a residential dining room, indoor or outdoor living area, or commercial spaces.

Frequently Asked Questions

Do I need to service my ethanol fireplace in any way?

Yes, normal maintenance and care is very important! Instructions are included in the Installation, Operating and Maintenance Manual supplied with your EcoSmart Fire product.
Is their heat output similar to a gas heater?

Burning bioethanol is similar to gas, but the room doesn't dry out like it does with gas - a more gentle, softer heat is created. Heat-wise, it depends on the models being compared. Some of our bioethanol burners output 15,000 BTU and can heat up to 60sqm of living space. Bioethanol is not, however, on an adjustable thermostat. Some may be turned up and down, but you can't control the room temperature in the same way as you do with gas on mains

How do I fill my ethanol fireplace?
With EcoSmart Fire’s proprietary tools and procedures, filling your ethanol fireplace with e-NRG bioethanol fuel is fast and easy.Step 1: Remove the bottle nozzle cap and carefully insert into the filling pointStep 2: Push and hold the green button. The nozzle will automatically stop filling once the reservoir is full.Step 3: Replace the nozzle cap.
What maintenance is required for ethanol fireplaces?
Clean your EcoSmart Fire unit after you have used 50 liters [13.20 Gal.] of fuel or as soon as you notice black deposits on or near the burner of the ethanol fireplace. Black marks can be removed from the stone, solid surfaces or stainless steel with a mild abrasive washing product such as JIF or similar. It is recommended to test a small area first to ensure the cleaning product chosen is appropriate and will not mark or damage the surface. Burners can be washed as required in hot soapy water (even in your dishwasher) from time to time and the internal mechanics won’t deteriorate like some other brands as all internal parts are stainless steel.
Can I extinguish my ethanol fireplace before the fuel has burnt?

Yes, you can turn your EcoSmart Fire ethanol burner off at any given time, even if there is ethanol still left in the burner. It is recommended however, that you leave it to burn until it completely runs out. The shut off mechanism is there for security and safety for those times when you need to leave the house, as it is not safe to leave a fire unattended. You need to wait until your appliance cools to room temperature (60 minutes) before re-igniting, this is because hot vapours are a hazard and may cause a strong, initial ignition if the ethanol has not cooled long enough. This is also to ensure that the flame has been totally extinguished and that the appliance is safe to refuel if the amount of fuel in the burner at that time is insufficient for your next ignition / use.

How much does it cost to maintain an ethanol fireplace?

EcoSmart Fire’s ethanol fireplaces require little maintenance. It is important to keep the lid closed when not in use to keep debris out of the ethanol burner that can cause corrosion and damages. The 304 stainless steel tank is built to last a lifetime if proper cleaning procedures are done when needed.

Are EcoSmart Fires easy to install?

EcoSmart Fires are designed to be easily installed and operated. Without the need for a flue or pipe connection, EcoSmart Fires are extremely flexible and can be incorporated at any stage of your interior decorating, renovating or building works. For detailed specifications please contact your local distributor.

  • Researched and ordered my fireplace from US FIreplace Store. Pricing was a fair value however, the customer service was EXCELLENT! I had an issue with the direct vent venting. I called US Fireplace and the correct items were sent out the next day AND Janessa stayed on top of my return authorization and sent me the permissions and documents I needed to return the incorrect item and no cost to me, including return shipping. Overall, I am a very satisfied customer and my fireplace looks and operates flawlessly. I am glad that I selected US FIreplace to source my direct vent fireplace. Thank you for the great service.

  • I had placed an order, through Lowe's Home Improvement, for an Electric Firebox: Revillusion RBF42. Ordered 1st part of January. Was told I would have it in 3 weeks. When checking to see is it came in, was told it was delayed to 3/15. Was then told is was delayed until 4/25. Waited until 4/27 to check on it. Was then told it was now delayed until August. This firebox was going in a new Sun Room addition. I could not get my final inspection until the Firebox was installed. I went on line and googled for this same product. US Fireplace Store web site was given to me. This was on a Saturday. I call and reached a very nice man. Explain what I was look for. He checked and told me they had 30 of them in stock. I almost fell out of my chair. I clarified with him the product I was wanting. I ask how soon could I get it. He told me it would ship today. Again, was amazed. It arrived on the following Monday. What a pleasure and a relief working with US Fireplace Store and their employees. Exceed my expectations.

  • Great prices, quick delivery and fast hassle free services on the issue I encountered. I had purchased an electric fireplace unit that would not fit into the existing fireplace space. With one email I was able to get the wrong fireplace refunded and picked up at my home at no extra cost and the new one I purchased and delivered free of charge. Great company.
