Direct Hot Surface Ignition System features an advanced silicon nitride igniter for years of reliable starts.
The RPJ® III primary heat exchanger is made of corrosion-resistant weld-free stainless steel. The unique integrated ripple-edged design forces more heat to the outside surface area for higher efficiencies.
Heating On Demand
Two-stage redundant gas valve, two-speed induced draft blower assembly, and variable-speed motor operate normally at the lower stage and ramp up as needed.
Variable-speed circulation blower motor is pre-lubricated, dynamically balanced, and resilient mounted to reduce vibration and noise.
State-of-the-art electronic controls monitor system operation and allow for advanced diagnostics, a timesaving tool for technicians.
