How do I switch my PENTAIR ETi 250 pool heater from natural gas to propane?

Converting your PENTAIR ETi 250 High-Efficiency Pool and Spa Heater from natural gas to propane gas involves several crucial steps and requires specific tools. Here's a breakdown to guide you: Tools You'll Need: Gather the necessary equipment. This includes a socket wrench, channel lock pliers, adjustable wrenches, a screwdriver, a hex key, pipe sealant, a pressure gauge, and a flue-gas analyzer. Gas Connection Prep: Before you begin, confirm your gas supply pressure is within the specified range of 4" to 12" wc. Install a manual shut-off valve and a sediment trap outside the heater jacket. Always use the gas pipe sizes recommended for propane gas supply piping. Gas Orifice Swap: Replace the existing gas orifice with the new one included in the conversion kit. Make sure the o-ring is correctly installed and that the gas orifice is seated flush inside the union. Air Orifice Replacement: Swap out the existing yellow air orifice for the new blue air orifice that comes with the kit. Use a socket wrench to secure the new air orifice. Air Flow Switch Update: Replace the existing Air Flow Switch with the new one included in the kit. Attach the bracket to the new Air Flow Switch and connect the PVC tubing. Verification and Testing: Once you've completed the conversion, use a pressure gauge to verify the gas supply pressure. Before you turn on the heater, always leak-test all gas connections using soapy water. Final Inspections: Double-check that the gas orifice union and the union outside the heater are secure, and that the air orifice is properly seated. Then, turn on the gas supply valve and the heater to observe its operation. Completion: If the combustion appears satisfactory and the exhaust analysis falls within the recommended range, complete the conversion. Attach the conversion label provided in the kit. By following these steps and using the correct tools, you can successfully convert your PENTAIR ETi 250 Heater from natural gas to propane, as per the manufacturer's guidelines.
