Description
Pentair ETi 250 High Altitude Conversion Kit 4,500–10,000 Ft | 462057
The Pentair ETi 250 High Altitude Conversion Kit (462057) is a specialized accessory designed for thePentair ETi 250 Condensing Gas Heater. This kit adjusts the combustion settings so the heater can operate safely and efficiently at high elevations between approximately 4,500 ft and 10,000 ft above sea level. At higher altitudes, thinner air affects combustion and burner performance, and this conversion kit helps ensure proper fuel delivery and combustion stability under those conditions.
What This Part Is For
This conversion kit is intended for use with the Pentair ETi 250 Condensing Gas Heater when the installation site is located at high elevation (generally above 4,500 feet). It includes the necessary orifices and components to optimize combustion for the reduced oxygen levels found at altitude, ensuring the heater meets performance and safety requirements when operating on natural gas (NG) or propane (LP) in thinner air.
Features & Benefits
