The ZLINE RA-HG-PK-48 Propane Conversion Nozzle Kit is designed to fit ZLINE 48-inch all-gas ranges with the High Grate configuration. This is compatible with 48-inch range models that start with the model numbers RA and include the High Grate option.
Quick answer: The ZLINE RA-HG-PK-48 Propane Conversion Nozzle Kit converts your 48" ZLINE all-gas range with High Grate burners from natural gas to liquid propane (LP). It's the exact replacement kit you need if your original LP orifices were lost, damaged, or never included. Always match the kit to your range's size AND burner configuration before ordering.
What This Kit Does
If your kitchen runs on liquid propane instead of municipal natural gas, your ZLINE range needs a different set of internal burner orifices. Propane burns at a different pressure and energy density than natural gas — the orifices in this kit are precisely sized to deliver the correct flame height, heat output, and safe combustion when your range is connected to an LP tank.
This kit is specifically designed for ZLINE 48" all-gas ranges that ship with the High Grate burner configuration. If your range is 36", you'll need the RA-HG-PK-36 instead.

Do You Actually Need to Buy This Kit?
Before you add this to your cart, check your situation:
✅ You need this kit if:
- You bought a pre-owned ZLINE 48" range with High Grate burners and the original LP kit is missing
- Your existing propane orifices were lost, damaged, or swapped
- You're converting a 48" High Grate natural gas range to propane and need a fresh kit
⚠️ You probably DON'T need this kit if:
- You bought a new ZLINE all-gas range — the LP kit is already in the box
- Your range is 36" — use RA-HG-PK-36 instead
- Your range uses standard grates — contact us for the correct kit
- You're not sure — contact us first →
⚠️ Professional Installation Required
Propane operates at a different pressure than natural gas, and the orifices in this kit must be installed correctly to ensure safe combustion. ZLINE requires that a licensed gas technician or plumber perform this conversion. DIY installation can void your warranty and create safety risks including irregular flame heights, carbon monoxide production, or gas leaks.
Buying a New Range Instead?
If you're shopping for a new ZLINE range rather than a replacement kit, here's something worth knowing: most new ZLINE all-gas ranges already include the propane conversion kit in the box. You won't need to buy this separately.
