Installation is intended to be straightforward for those comfortable with basic appliance connections. The kit includes the essential fittings and hand tools to secure hoses and regulator connections; however, orifices are not included and may be required for some burners. If you’re unsure or want to ensure code compliance, have a qualified technician perform the final hookup and leak testing.

• Recommended step: perform a pressure/leak test after installation

What does the kit include and why each part matters?

The kit combines the components required to convert fuel type and establish a secure natural gas supply. The regulator adapts incoming line pressure to the grill’s needs, while the quick-connect 10 ft hose gives flexibility in positioning the grill relative to your gas line. The hand tools help tighten fittings to create gas-tight connections and reduce the chance of leaks.

• 10 ft natural gas hose with quick connector — extends reach to the gas outlet
• Natural gas regulator and 5.9 in regulator hose — controls line pressure for safe burner performance
• 6 mm wrench, nut driver, hex key — tools to secure fittings without extra purchases
• No orifices included — buy model-specific orifices if required

Can I switch back to propane after installing this conversion kit?

Reverting to propane is possible but requires reinstalling the original propane regulator, hoses, and any propane-specific orifices removed during conversion. Keep original parts in a safe place if you anticipate switching fuels, and follow manufacturer instructions to ensure correct connections and safe operation each time you change fuel type.

• Keep original propane regulator and hoses for reversal
• Reinstall model-specific orifices for proper fuel flow
• Always perform a leak check after any fuel-change work

This SPIRE Natural Gas Conversion Kit is for grill owners who want a reliable, continuous natural gas supply instead of swapping propane tanks. It suits owners of the listed SPIRE and KA models who are comfortable with moderate DIY tasks or who have access to professional installation. If you need orifices, manufacturer-specified parts, or local plumbing work, factor that into your plan and budget before installing.
