FAQ's

Where is the best place to install an ethanol fireplace?

Our ethanol fireplaces can be installed virtually anywhere - in walls, cabinets, high rise buildings, commercial / residential / hospitality spaces, indoors and outdoors. Because EcoSmart Fire’s ethanol fireplaces are ventless, they require no gas line, no electricity, and no chimney for a hassle free and cost effective installation. Our ethanol fireplaces have been designed and tested with safety as our top priority. We have outlined requirements for each ethanol burner, ethanol fireplace insert, and ethanol freestanding fireplace in our collection. These guidelines include minimum room size requirements and clearance recommendations for flammable materials and movable objects. Please refer to our manual for more information.

How to install a TV or AV equipment above an ethanol fireplace?

This design can be achieved as long as the TV is protected. You have 3 possible solutions:

Solution 1: The TV needs a non-combustible mantel/ledge to act as a heat shield

Solution 2: The TV needs to be recessed in a niche

Solution 3: The TV needs to sit back off the level of the flame

How to position your TV

How safe are bioethanol fireplaces?

EcoSmart Fire’s operating tools, procedures, and proprietary technologies were developed with safety as our top priority. Made from 304-grade stainless steel, EcoSmart Fire’s ethanol fireplace burners go through a deep-draw fabrication process that eliminates the potential for dangerous leaks. Additionally, our patented filling point is separated from the ignition zone and engineered so that the jerry can spout is fully supported prior to releasing the fuel supply. This eliminates the usual splash and spills that would otherwise occur when fuel is decanted into the burner while simultaneously reinforcing the maximum fill line within the burner. EcoSmart Fire’s ethanol fireplaces release heat, carbon dioxide (the same stuff we exhale) and steam. Allowing you to enjoy a clean-burning flame without the soot, smoke, ash or other harmful substances emitted by traditional wood burning fireplaces. When selecting an installation location for your ethanol fireplace it is important to consider the required minimum room sizes and clearances. Please reference our installation manual for more information.

What is bioethanol fuel?

Bioethanol (also known as methylated spirits or simply ethanol) is a form of renewable energy. It’s a clear, colourless liquid that’s commonly made from fermenting the sugar and starch components of plant by-products like sugarcane and grain crops.

Where do I buy ethanol fuel for my ethanol fireplace?

e-NRG is the only bioethanol fuel recommended for your ethanol fireplace. e-NRG has been produced for the lowest odor, most vibrant flame, and longest burn time on the market. e-NRG has undergone rigorous third party testing with all EcoSmart Fire ethanol fireplaces. Use of any other fuel may damage your unit and void your warranty. You can purchase e-NRG ethanol fuel at e-nrg.com for fast and free shipping.

What are the benefits of a zero clearance ethanol fireplace insert?

EcoSmart Fire’s Flex Fireplace Series has the necessary clearances to combustible frame components already built-in meaning they can be framed with wood studs. This gives you the freedom to install your ethanol fireplace insert in small and unique spaces. When selecting a location for the fireplace it is important to consider the required minimum room sizes and clearances. Please reference our Flex Series installation manual.

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 point

Step 2: Push and hold the green button. The nozzle will automatically stop filling once the reservoir is full.

Step 3: Replace the nozzle cap.

You can view a step-by-step filling video.

Why use an ethanol fireplace?

An ethanol fireplace is an eco-friendly and cost-effective alternative to gas fireplaces and wood burning fireplaces. Enjoy the warmth and aesthetic benefits of a traditional fireplace without the smoke, soot or ash in your home. Unlike gas fireplaces or traditional wood burning fireplaces, EcoSmart Fire’s ethanol fireplace inserts require no venting, no gas line, no electricity - eliminating the need and cost of three sub contractors.
