It boasts energy-efficient features such as a seven-stage modulating gas valve and a variable speed inducer motor, which help in maintaining consistent and cost-effective heating.

The electronic spark ignition and electronic thermostat, which ranges from 60°F to 80°F, offer precise control over the heating process. Additionally, its direct vent design ensures safe and efficient operation by expelling combustion gases directly outside. Safety is another strong point with this furnace, featuring child lock and self-diagnostic electronics that provide auto shutdown codes and automatic restarts in case of ignition or combustion failure. These features ensure peace of mind, especially in homes with children.

The design includes timer settings for added convenience and a relatively compact size that can be wall-mounted, saving floor space. However, it's worth noting that this model has been discontinued, and potential buyers might need to look at the new model, EX38DTN, for updated features and support. The heater's weight of 88 pounds means it requires proper installation support, and assembly is needed.

With a heating capacity of 21,500 BTU, it effectively warms a variety of spaces while maintaining consistent temperatures. This model utilizes advanced modulating technology, which reduces cold spots, ensuring a comfortable environment throughout your home.

One of the standout features is its energy efficiency. The heater is designed to minimize fuel consumption by adjusting heat output based on your specific needs, which can lead to noticeable savings on energy bills. The programmable thermostat further enhances this efficiency, allowing you to set and maintain your preferred temperature easily.

It can fit seamlessly into various room layouts without becoming an eyesore. Additionally, the unit operates noiselessly, providing a quieter alternative to some traditional heating systems.

While the heater is efficient, its initial purchase price might be higher compared to some less advanced models. Also, as it requires professional installation due to its direct venting system, this could add to the overall cost. Potential users should ensure that their home’s ventilation system is compatible with this type of heater, as this could limit installation options.

The heater boasts a programmable thermostat for precise temperature control and adaptive heating, making it a convenient choice for maintaining comfort during colder months. Notably, the heater features several safety mechanisms, including a flame failure device, overheat switch, oxygen depletion sensor, and tilt switch, which help ensure safe operation by automatically disabling the heater if hazards are detected.

Additionally, the cool-to-touch child-safe cabinet and safety lock offer peace of mind for households with children. The ventless design simplifies installation, though professional installation is recommended to ensure proper setup and safety compliance.
