Ultra-High ASME® certified performance in a compact, quiet, and eco-friendly design for your commercial application.

• The bronze header design allows for easy access to the thermal regulator and bypass valve service without the use of special tools.
• Upgrades to the thermal regulator include a governing stainless steel sleeve for better wear protection.
• All internal components of the bronze header are now plastic for lightweight, corrosion, and wear protection.
• The ignition Control Module includes more diaphragm spring force for better gas control and robust operation.
• A fuller pre-mixed system with a highly efficient air and gas mixture allows for faster heat-up times.
• Efficiencies up to 84%
