Product: GordonRay^® DF

Description: Due to its ability to fire at two distinct rates, this product provides energy-efficient heat that can effectively adjust to sudden high heat-loss conditions or economically maintain steady comfort levels. This dual-stage heater connects to a two-stage thermostat that uses an algorithm to control the heater’s output based on load conditions. If the thermostat does not sense a temperature rise during a heat cycle, it will prompt it to operate in high-fire. Once a steady heat rise is sensed, the heater will then go to low-fire until the call for heat is met. The two-stage thermostat has an internal memory that automatically adjusts the output to improve operation efficiency during each cycle. Other features include: dual-burner status-indicator lights, eternal thermostat connection points that can also power a low-voltage thermostat, a hinged door for easy access to electrical components during annual maintenance and fall season startup, and an internal partition that separates the combustion air from the electrical components for reduced maintenance.
