Direct Vent Gas Fireplaces

Direct Vent Gas Fireplaces burn natural gas to create heat and flames. They are versatile and easy to install. Enjoy a Direct Vent Gas Fireplace in the living room, bedroom, the basement, kitchen, bathroom, den, and even the home office – wherever you want to enjoy the comfort and warmth of a fire. Direct Vent Gas Fireplaces average about five times more efficient than traditional fireplaces while maintaining air quality and evenly distributing heat throughout a space.

Installation eliminates drafts because the unit is completely sealed and requires no chimney for venting, also ensuring that no gases are released into the home. Cooler air is drawn into the firebox from the outside, which then efficiently pushes the hot air inside the box out through the venting. Indoor air is pulled in and circulated around the outside of the box that is heated by the fire and moved into the room for cozy heat. One of the best parts about a Direct Vent Gas Fireplace is that they do not require electricity to operate. Instead batteries or a self-sufficient control can light the fireplace in the event of a power outage, ensuring light and warmth.

Featuring premium log sets for a traditional look, the Ascent X Series offers you a wide range of heat output options and control.

Napoleon’s exclusive NIGHT LIGHT™ illuminates the firebox for a comforting glow even if the flames are off.

        • 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.
