LP-to-NG (or NG-to-LP) Conversion on Crown Verity Grills
Conversion kits exist for most Crown Verity models, but installation is NOT a DIY job — a licensed gas technician must do the work.

What you need
Step by step
Confirm your model allows conversion
Natural Gas models have part numbers ending in NG. Propane models are built for standard 20-lb tanks. Built-in models end in NG or LP. Not every model has a conversion kit — call 1-888-505-7240 with your serial to confirm.
Order the correct kit from Crown Verity or an authorized dealer
Kits include orifices and sometimes regulator components sized to the destination fuel. The kit must match your exact model and generation.
Have a licensed gas technician install
The technician will swap the orifices, adjust the regulator, verify pressure at the manifold (NFPA 54 / CSA B149.1), and leak-test every connection. They should document pressure readings for your records.
Update the rating plate record
Keep a note of the conversion (date, technician's license number, new fuel type) attached to the warranty folder. If you ever sell the grill, disclose the conversion.
Common mistakes
- DIY orifice swap without regulator adjustment. Just changing orifices without adjusting the regulator causes the grill to run too lean or too rich — poor performance and a safety risk.
- Using a rigid gas pipe for a built-in connection. Built-in grills need a flexible corrugated stainless steel hose (not rigid pipe) between the supply line and the grill — so the grill can be pulled for service.
Hands-on tips
- Converting to NG is usually the right call for a permanent patio install (no tank swaps). Propane is the right call if you move the grill or can't run a gas line.
- Built-in grills include a factory-set regulator but no hose — the gas tech specs the hose length to your plumbing.
Questions people ask
Can I convert a Mobile grill back and forth as needed?
Not practically — each conversion is a service event. Pick the fuel type you'll use most and stay.
What's the operating pressure for a built-in grill?
Rating plate on the grill lists the correct operating pressures. The gas tech verifies at the manifold.
