The Duet see-through fireplace is a lyrical expression of industry-defining technology and luxurious contemporary design. The only double-sided wood burning fireplace that meets the EPA’s most exacting emission standards, the Duet confirms Supreme’s position as the industry leader of clean burn technology. It is the perfect choice for environmentally-aware consumers seeking an efficient two-sided fireplace that doubles as a striking visual feature.
The combustion chamber has been refined over many years to offer the ability to burn large logs while remaining compact enough not to impede the flow of light and movement within a space. The Duet serves as a visually compelling feature in any interior scheme, whether installed as a centrepiece or as a decorative divider between two rooms.
Enjoy the views of the dancing flames from two sides along with an impressive ability to heat a room within minutes. Courtesy of several patented technologies, the Duet ensures user-friendly ignition and operation of the fireplace along with fires that can last throughout an entire night. Adding to the sense of the delight is the drop down grill that allows flavorsome barbecued meals to be prepared over the coals.
The Duet will introduce a sense of harmony along with superior heating capability to your home.


  • Stainless Steel Firebox: A result of more than 30 years of pioneering research and development, our combustion chamber provides superior heat transfer; within minutes of lighting, radiant warmth will be permeating your home. Unlike traditional fireboxes built with refractory bricks, prone to cracking, our heavy-duty chamber will last the test of time. We guarantee its reliability and durability with a market-leading, 25-year limited lifetime warranty.
  • Patented Automatic Air Control: This patented, user-friendly mechanism automatically reduces the amount of combustion air introduced during ignition to the desired burn rate setting. The result is a beautifully consistent fire burning to its full capacity.
  • 2 Premium Blowers (135 CFM Total): This powerful yet whisper-quiet system effortlessly distributes heat over significant distances. As the combustion progresses, the high-quality blower automatically activates and is set using the variable speed controller.
  • Built-In Barbeque Grill: This exceptional feature offers the ability to create meals imbued with flavorful smokiness inside the comfort or your own home. Simply drop down the grill once the wood has reduced to embers and place your food inside; the result is memorable barbecued dishes all year-round.
  • Sealed Ash Pan: Simple and mess-free: Ashes fall through a perforated grate into the sealed ash pan that is effortlessly removed and emptied.
  • Removable Ash Lip: Offering another layer of protection against ashes, this removable accessory can be attached below the door to prevent spills when the fireplace is opened.
  • Easy-Light Control: There is no need to bother with kindling wood or newspaper when lighting our products. The patented easy-light mechanism releases a quick boost of air to aid ignition, ensuring warming your home is as simple as pushing a button.
  • Chimnet Sweeping Cap: Located on the baffle, this convenient feature allows the chimney to be easily accessed for cleaning, without requiring the removal of any additional components.
  • Unique Door Operation: Our finely crafted door handle has an ergonomic design and keeps the door shut by means of a latch for a secure operation.
  • Hot Air System : Enjoy watching the beauty of your fire for longer thanks to this advanced design feature. Pre-heated air is forced onto the glass viewing pane, keeping it clean from soot even while burning at low temperatures.
  • Innovative Baffle Design: Most EPA units on the market feature secondary air tubes that hamper access to the chamber when filling it with wood and require constant maintenance and regular replacement. Instead, our products have a unique design that allows secondary air to enter through a perforated baffle offering an unimpeded viewing area to the fire all while increasing the efficiency and prolonging the combustion.
  • Patented Variable Secondary Air Control: This patented control introduces a variable amount of secondary air into the firebox via a downward path that mixes with the rising gases of the wood. The result is a unique, appealing arrangement of flames that prolongs the combustion, increases the efficiency of the fire and minimizes the amount of emissions released.
