Concentric Vent or 2 in. Exhaust: Allows for easy use of concentric 2/4 in. or 3/5 in. direct vent or exhaust in 2 in. pipe or room-air configurations
2 in. Intake Vent Connections: Allows for maximum flexibility with the use of 2 in. PVC/CPVC/PP on vent runs up to 65 ft.
Primary Stainless Steel Heat Exchanger: Resists the corrosive nature of the condensate, which occurs early in the highefficiency combustion process
Fiber Mesh Premix Burner: Provides even flame distribution for optimal performance for any demand
Integrated Check Valve: Located between the turbo fan and combustion chamber. Prevents cold air from entering the venting system and backflow of exhaust in common vent applications
Turbo Fan: Enables longer vent runs and flexible vent options. Up to 65 feet vent runs with 2/4 in. concentric and 2 in. PVC/CPVC/PP. Up to 150 ft. vent runs with 3/5 in. concentric and 3 in. PVC/CPVC/PP
Switching Venturi: Provides consistent mixture of air and gas to burner for low turndown ratios. Self-compensates in areas with low or fluctuating gas pressures
NEW Zero Governor Gas Valve: Optimizes combustion performance by consistently delivering gas and air mixture
