• ProTek Shield — replaceable corrosion-protection module that extends heat exchanger life
• Digital LCD thermostat with on-board diagnostics — live water temp readout and fault codes displayed on the panel

Rated for 0–2,000 ft elevation only. Verify your propane supply line sizing with a licensed gas technician before install — undersized LP lines are a common cause of ignition and performance issues on high-BTU heaters.
