EX22DTWN is a quick, flexible installed, ductless, natural gas, direct vent wall furnace from Rinnai; the perfect supplemental or specific zone heating solution that seeks out cold spots and within seconds begins to gently heat the room or space for maximum comfort. WiFi enabled thermostat connection ready.

The EnergySaver Direct Vent Wall Furnaces feature modulating technology to optimize the efficiency of the unit. It offers just the right amount of heat at any given moment by constantly monitoring the room temperature and detecting temperature fluctuations. Room temperature is monitored 2" from the floor and detects temperature changes of less than 1°F. If a door opens and a sudden gush of cold air rushes into the room, the furnace automatically adjusts the fan speed and BTUs to restore the room back to its set temperature quickly.

The EX22DT features a built-in humidifier tray. The 1.5 pint, the enamel-coated tray is located on the bottom front of the unit for easy access. As warm air passes over the water in the tray it is humidified.

It is recommended that you allow for 40 inches of clearance in front of the unit and 10 inches from the top and sides to allow for easy maintenance and service access.

    • 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.
