ZLINE Propane Conversion Guide: Which Kit Fits Your Range? (2026)

If you've landed here, you're probably staring at a ZLINE range wondering whether you need a propane conversion kit — and if so, which one. Maybe you bought a used range and it didn't come with one. Maybe you're switching your home from natural gas to propane. Or maybe you're just trying to figure out what this part even does before you spend money on it.

Good news: this isn't complicated once someone explains it plainly. So let's do that.

💡 What Is a Propane Conversion Kit?

Natural gas and propane (LP) are not interchangeable fuels, even though your range can burn either one. The difference comes down to pressure and density. Propane is a denser fuel, stored and delivered at higher pressure than natural gas.

If you hooked a natural-gas-configured range up to a propane line without changing anything, you'd get a flame that's too large, unstable, and inefficient — and potentially unsafe.

A propane conversion kit fixes this mismatch. It typically includes:

• Brass orifices — small, precisely drilled fittings that sit at each burner. Propane orifices have smaller holes than natural gas orifices, because propane needs less volume to produce the same heat output.
• Pressure regulator components — these manage the fuel pressure coming into the range so it matches what propane requires.

Swapping in the correct orifices and regulator parts recalibrates your range to burn propane cleanly and safely, with the same flame quality and cooking performance you'd expect from natural gas.

This matters for more than convenience. Incorrect pressure or orifice sizing can cause incomplete combustion, which produces more carbon monoxide, along with soot, uneven flames, and long-term burner damage. This is a safety component, not just an accessory.

🔥 Do You Actually Need to Buy One?

This is the first question worth answering honestly, because the answer depends entirely on your situation.

If you're buying a new ZLINE all-gas range: Most new ZLINE all-gas ranges ship with the propane conversion kit already included in the box. You won't need to buy one separately — you'll just need a licensed technician to install it if you're running on propane from day one. Browse the ZLINE All-Gas Ranges collection if you're still shopping.

Buying new and leaning dual-fuel? Those work differently — only the cooktop needs conversion, and the kits are model-specific. Take a look at our ZLINE Dual-Fuel Ranges collection to see what's included with each model.

If you have a pre-owned or previously installed ZLINE range: This is where most people end up needing to buy a kit separately. If the range changed hands, was installed by a previous owner, or the original kit was lost, tossed, or never used, you'll need to purchase the correct kit on its own. This is the single most common reason people find this guide.

If you have a dual-fuel range: Dual-fuel ranges (gas cooktop, electric oven) work a little differently. Only the cooktop burners need conversion — there's no oven-side gas component to worry about. Dual-fuel LP kits are also model-specific, which is why ZLINE sells separate high-grate kits for dual-fuel ranges rather than using the same kit across the board.

✅ Which Kit Fits Your ZLINE Range?

This is where people most often get tripped up — not because it's hard, but because two things have to match: range size and burner configuration (Standard Grate vs. High Grate).

*The RA-PK-30 is made for 30" dual-fuel ranges. We don't currently stock this kit ourselves, but it can be ordered directly from ZLINE Parts (zlineparts.com). Always confirm your exact model's kit requirement against your data plate before ordering.

Here's what those model names are actually telling you:

• RA-PK-30 — the standard propane conversion kit for 30" dual-fuel ranges. We don't carry this one in our store, but it's available directly from ZLINE Parts (zlineparts.com) if this is your size.
• RA-PK-36 — a standard propane conversion kit, sized for ranges with standard grates. View the RA-PK-36 product page.
• RA-HG-PK-36 — "HG" stands for High Grate, built specifically for 36" dual-fuel ranges with the high-grate burner design. View the RA-HG-PK-36 product page.
• RA-HG-PK-48 — the same high-grate design, sized for 48" dual-fuel ranges. View the RA-HG-PK-48 product page.

🔥 Installation: Why You Shouldn't DIY

We're going to be straightforward here: this is not a project for a Saturday afternoon and a YouTube video.

Propane runs at higher pressure than natural gas, and the entire point of the conversion kit is to correctly recalibrate your range for that pressure. Getting it wrong isn't a "the burner looks a little weird" problem — it's a gas leak, fire, or carbon monoxide problem.

A licensed technician typically charges a modest service fee for this kind of job, and it buys you certainty that the pressure, orifice sizing, and regulator setup are all correct. This is one of the few areas where it's genuinely not worth trying to save the labor cost yourself.

💬 Common Questions & Misconceptions

✅ The Bottom Line: Buy the Kit or Buy a New Range?

If you already own a ZLINE range and it's just missing the conversion kit — buy the kit. It's a small, inexpensive part relative to the cost of the range, and it's the correct fix for exactly this situation. There's no reason to replace a perfectly good range over a missing accessory.

If you're in the market for a new range and know you're running on propane, look for ZLINE all-gas models, most of which include the LP kit standard. That saves you a separate purchase entirely.

Either way, match your kit carefully to your range's size and burner configuration, and have it installed by a licensed gas technician. That combination — the right part, installed correctly — is really the whole safety story here.
