Product Overview
Designed for recessed, single-sided installations, this 72-inch Bio Flame firebox creates a wide architectural flame presentation for contemporary living rooms, hospitality interiors, commercial spaces, and custom feature walls. Bioethanol fuel allows the fireplace to operate without a chimney, vent, gas line, or fixed fuel supply.
The firebox is constructed from 304-grade stainless steel and uses a fully insulated, double-walled design. An internal brushed stainless steel frame and 8 mm tempered-glass windscreen complete the built-in assembly while helping protect the flame from drafts.
This version includes a 60-inch manual burner with an approximate 18-liter fuel capacity and an indicated burn time of approximately 10 hours. The manual burner does not require an electrical connection for normal operation, but all installation, room-size, clearance, and ventilation requirements in the manufacturer manual must be followed.
Important: Bioethanol fireplaces are classified as decorative appliances intended for occasional use. Do not select this model as a primary or continuous heating system.

Key Features and Buyer Benefits
60-Inch Manual Burner
The included manual burner creates a broad linear flame and is operated using the supplied lighting tools. No fixed electrical or gas connection is required.
Ventless Bioethanol Operation
Bioethanol fuel eliminates the need for a chimney, flue, or gas line, allowing greater design flexibility than many conventional fireplace systems.
304 Stainless Steel Construction
The firebox body is manufactured from 304-grade stainless steel for a durable, architectural built-in installation.
Fully Insulated Double-Wall Design
The insulated, double-walled structure is designed to isolate heat within the firebox assembly when installed according to the manufacturer instructions.
8 mm Tempered Glass
The included tempered-glass windscreen helps protect the flame from drafts. Do not operate the fireplace without the glass correctly installed.
Indoor and Protected Outdoor Application
The firebox is listed for indoor and outdoor use, but an outdoor installation must be protected by an overhang and must not be exposed directly to water.
Long Flame Presentation
The 72-inch firebox and 60-inch burner are suited to large-format media walls, architectural surrounds, and commercial focal points.
No Permanent Fuel Connection
The manual burner is filled directly with approved bioethanol fuel and does not require a permanent fuel pipeline.
Certified Burner System
Bio Flame burners are CE certified and tested in accordance with the EN 16647 standard for bioethanol fireplace appliances.
Available Finish and Front Configurations
The 72-inch single-sided firebox is offered in black or silver finishes and in Flush or Spacer configurations. Choose the option that matches the intended wall detail and surrounding finish.
Flush Configuration
The Flush version is designed so the front presentation aligns closely with the finished frame or wall treatment, creating a clean and integrated built-in appearance.
Spacer Configuration
The Spacer version positions the front slightly away from the frame, creating a more defined offset between the fireplace and the surrounding finished surface.
Review the selected SKU and physical unit before final framing. The manufacturer states that dimensions can vary by approximately 2% and recommends using the actual firebox when determining final cutout dimensions.

Single-Sided Installation Requirements
This firebox must be installed according to the manufacturer manual and all applicable local requirements. The surrounding structure and installation surface must be capable of safely accommodating the appliance and its operating temperatures.
Framing Opening for the 72-Inch Manual Model
-
Opening Width: 69.64" / 1768.8 mm
-
Opening Depth: 14.49" / 368 mm
-
Opening Height: 6.5" / 165 mm
Required Installation Materials
- Use non-combustible materials around the firebox.
- Line the firebox cavity with at least 3/8-inch cement board.
- Mount the unit on a level, non-combustible surface.
- Secure the firebox to the supporting structure before operation.
Installation Sequence
- Build the main framework using the specified opening dimensions for the 72-inch, single-sided firebox with 60-inch manual burner.
- Line the base and firebox cavity with non-combustible cement board before inserting the firebox.
- Center the firebox within the base and confirm that it sits level and stable.
- Continue framing around the firebox with cement board separating the firebox from the surrounding studs.
- Install the upper horizontal support and anchor the firebox securely through its mounting flange and brackets.
- Complete the surrounding wall with suitable materials and install the tempered-glass windscreen before operating the appliance.
Do not install beside heat-sensitive finishes. Wallpaper, laminate, veneer, adhesives, and other materials not designed for high temperatures can discolor, deform, or fail when exposed to heat.
Clearance, Ventilation, and Location Rules
Combustible-Material Clearance
Select a spacious, open location and maintain at least 1500 mm / 59.1 inches from combustible materials such as curtains, wallpaper, veneer, furniture, paper, or other ignition hazards.
Minimum Room Size
The 72-inch firebox with 60-inch manual burner requires a minimum room size of 100 m². Do not install it in a room that cannot meet this ventilation requirement.
Installation Below a Television
When installed beneath a recessed television, maintain at least 14 inches / 35.5 cm between the top of the firebox and the bottom of the television.
Outdoor Location
Outdoor installations must be placed beneath a protective overhang. Damage caused by installation in an exposed location is not covered by the manufacturer warranty.
A ventless fireplace still requires adequate room ventilation. “Ventless” means the appliance does not require a chimney or flue; it does not eliminate the minimum room-size, airflow, or clearance requirements in the installation manual.
Fueling and Operating Safety
Approved Fuel
- Use The Bio Flame Bioethanol Fuel or the manufacturer-listed e-NRG alternative.
- Never use gasoline.
- Keep fuel in its original container.
- Store fuel away from heat and ignition sources.
Before Refueling
- Confirm that the flame is fully extinguished.
- Allow the burner to cool completely.
- Confirm that the fuel chamber is empty.
- Clean and fully dry any spilled fuel before relighting.
During Operation
- Never leave the flame unattended.
- Keep children and pets at a safe distance.
- Do not move the firebox or burner while in use.
- Do not operate near oxygen tanks or flammable vapors.
Prohibited Uses
- Do not cook food or boil water over the flame.

Flame Authority Recommendation
Who Is This 72-Inch Firebox Best Suited For?
Choose this model when the project calls for a large, uninterrupted single-sided flame presentation without adding a chimney, gas pipeline, or conventional fireplace vent. Its size is best suited to spacious rooms and commercial interiors that can meet the manufacturer’s 100 m² minimum room requirement.
Do not choose this model solely for primary heating. It is a decorative, occasional-use appliance, and its installation requires non-combustible construction, adequate room ventilation, the supplied glass windscreen, and compliance with all manufacturer clearances.
Frequently Asked Questions
Does the Bio Flame 72-Inch Firebox require a chimney or vent?
No chimney or flue is required. The room must still meet the 100 m² minimum size and all ventilation requirements in the installation manual.
Does the 60-inch manual burner require electricity?
The included manual burner does not require an electrical connection for normal operation. Electricity is required only if a compatible powered burner upgrade is selected.
Can this ethanol firebox be used as a primary heat source?
No. Bioethanol fireplaces are decorative appliances intended for occasional use and must not replace a primary heating system.
What is the minimum room size for the 72-inch manual firebox?
The minimum room size is 100 m² for the included 60-inch manual burner. Do not install the unit in a smaller room.
Can the 72-inch Bio Flame firebox be installed under a television?
Yes, when the television is recessed and at least 14 inches above the top of the firebox. Additional protection can be necessary for heat-sensitive equipment or finishes.
Can this firebox be installed outdoors?
It can be installed outdoors only beneath a protective overhang. Do not install it where rain, water, or direct weather exposure can damage the appliance.
What fuel should be used in the Bio Flame manual burner?
Use The Bio Flame Bioethanol Fuel or the manufacturer-listed e-NRG alternative. Never use gasoline or an unapproved combustible liquid.
Can I refill the burner while it is still warm?
No. Refill only after the flame is extinguished, the burner is completely cool, and the fuel chamber is empty.
Can the firebox be installed into combustible framing?
The firebox must be surrounded by non-combustible materials and the cavity must be lined with at least 3/8-inch cement board. Do not place heat-sensitive finishes directly beside the appliance.
Can the fireplace be operated without the glass windscreen?
No. Removing or failing to install the glass voids the approval for use with the included burner and can void the warranty.
What is the difference between the Flush and Spacer versions?
The Flush version aligns more closely with the finished frame, while the Spacer version sits slightly away from it. Confirm the selected SKU before completing the surrounding wall.
How long does the 60-inch manual burner operate?
The manufacturer lists an approximate burn time of 10 hours with an 18-liter capacity. Actual performance varies with fuel quality, installation conditions, and operation.
Does this firebox include automatic refilling or WiFi control?
No automatic refilling or WiFi control is documented as included with these manual-burner SKUs. Confirm a separate SmartFlame upgrade before ordering powered controls.
Should I frame the opening from the published dimensions alone?
No. The manufacturer allows approximately ±2% dimensional variation and recommends using the actual firebox for final cutout measurements.
Confirm Your Installation Before Ordering
Verify the selected finish, Flush or Spacer configuration, room size, framing dimensions, non-combustible materials, clearances, and local installation requirements before purchasing this 72-inch bioethanol firebox.
