I don't know about this one, but if you're looking for direct vent linear gas fireplaces, there are several manufacturers, including Spark, Montigo, Napoleon, Majestic, and Heat N Glo. All are sealed units with a required glass front. The unit in the picture does not appear to have a glass front.

Good call, @eggfarkarch.

I believe the photo above is a marketing photo of the <b>Heat & Glo</b> RED linear fireplace: http://www.heatnglo.com/en/Products/RED-Series-Gas-Fireplace.aspx

The odd thing is that the website shows a metal frame around the glass front. I believe the lack of a glass reflection is simply some Photoshop magic, just as is the addition of the glass frame.

I think it could also be a Modern Flames fireplace, was just at a home show and they had something that looked exactly the same!

Modern Flames makes beautiful fireplaces, but they are all electric, and the one shown above is gas.
This is a Modern Flames fireplace:

@COASTROAD Hearth & Patio - you are spot on!

This is the Heat & Glo RED Series Gas Fireplace. This same fireplace also comes in a see-through version for impact in two rooms. The site has more pictures of the finishing options that are available. We're also more than happy to help if you have any other questions!
