Converting a Natural Gas Fire Pit to Propane

As an Amazon Associate we earn from qualifying purchases. Details

Converting a natural gas fire pit to propane is a question about your own appliance, and the answer is in its manual and in the kit the manufacturer sells for it. The listings we saved do not give you a conversion procedure, and none of them is a conversion kit for another brand’s natural gas pit. This guide explains what the listings do show, what to check before you buy, and when a propane fire pit you can buy as a complete unit makes more sense than converting one.

At a glance: the 2 picks, by their own spec fields

Pick	Output	Dimensions / weight	Included accessories
Outland Living, 19″	58,000 BTU/hour	19x19x11 in, 23 lbs	Cover, carry kit, 10ft pre-attached hose with regulator, lava rock; CSA approved; 1-year limited warranty
Ciays Large, 19″ (grate + folding legs)	58,000 BTU	19.49×16.93×9.45 in (folds to 19×8 in), 23 lbs	10ft preassembled hose, grate, lava rock, hose hooks, carrying strap, tank holder, lid; piezo ignition, flameout protection

Specs are from each product’s Amazon listing, checked 2026-10-18 (full citations in this guide’s sources section). Neither pick is a natural-gas-to-propane conversion kit — both are complete new propane fire pits. Neither includes the 20-lb propane tank itself. If you specifically need to convert an existing natural gas pit, look for a conversion kit accessory instead of these full units.

Quick answer

Start with your existing fire pit. Find the model number and the manual, then contact the manufacturer or its dealer for a propane conversion kit made for that model. A kit is model-specific, so a part from one brand is not a safe bet for another. If the manufacturer offers no kit for your model, the simpler choice is to buy a complete propane fire pit. Two complete propane fire pits from the listings are described below, both rated at 58,000 BTU in their listings.

What the listings show

The Outland listing mentions a natural gas kit, not a propane one

The Outland Living listing says it includes a pre-attached 10-foot hose and a regulator, and it lists a “CSA approved Natural Gas Conversion Kit 780″ as an optional accessory. That kit name points the other way: it appears to convert a propane pit to natural gas, not a natural gas pit to propane. The listing does not say what it fits or whether it works with other brands. Do not read it as a propane conversion kit for your pit.

What the propane listings do state

Both propane listings we saved state a fuel type of liquefied petroleum gas, which is what a propane tank supplies. The Outland listing gives a maximum gas supply pressure of 250 PSI and a regulator with a chrome valve knob. Neither listing describes how to convert a natural gas unit, and neither says whether its burner can be fitted to another pit.

Gas use and local rules

A gas fire pit is for outdoor use only. Follow the manufacturer’s manual for lighting, hose connection and tank handling. Local codes and fire restrictions also apply, and the Outland listing says to check current fire restrictions in your area before use. Gas lines, regulators and burner parts are not a place for improvised parts. If your manual calls for a licensed installer or your local code requires one for a gas line change, follow that requirement.

Products worth checking

When buying a new propane pit makes more sense

If the manufacturer has no propane kit for your model, or the kit costs more than a new unit, buying a complete propane fire pit is the simpler route. Keep the old natural gas pit out of service until you know its condition. A complete unit also removes the question of whether a burner or regulator is compatible with your setup. Check the listing’s fuel type, BTU rating and hose length against your gas source before you buy.

Propane tank and fittings

Both listings are built around a propane tank, and the Outland listing names a standard 20-pound cylinder as the one it expects, but that cylinder is not included. Plan the tank position and the hose route before you set the pit down. Worked example (rough estimate, not from a listing): a 20-pound tank holds about 430,000 BTU if propane contains about 21,500 BTU per pound, a common reference figure. At the Outland listing’s 58,000 BTU per hour, that is about 7 hours at full output. Burn rates drop at lower settings. For national standards on outdoor gas appliances, see the National Fire Protection Association. For tank choice, see our guide on propane tanks for a gas fire pit and our guide on 20-pound propane tanks for a patio heater. For a burner accessory question, see air mixers for a propane fire pit.

Mistakes to avoid

• Using a kit from another brand. Conversion parts are model-specific.
• Reading an accessory name as a conversion kit. The Outland listing’s kit points from propane to natural gas.
• Using a pit indoors or in a garage. Both listings are for outdoor use. Check the manual before any use in an enclosed space.
• Assuming a warranty. The Outland listing gives a one-year limited warranty. The Ciays listing gives none in the specs we saved.

How we chose these products

We did not test either fire pit. The specs and claims come from the Amazon listings we saved, checked on 2026-10-18, and the bullets are the seller’s claims. The research file for this keyword holds four listings: the two propane units, a wood-burning pit and a patio heater reflector. We left out the last two because they do not match a gas fire pit. We found no conversion kit for a natural gas pit in that data.

Frequently asked questions

Can I convert a natural gas fire pit to propane myself?

Only if the manufacturer’s manual and kit allow it, and only by following the manual exactly. For a gas line or regulator change, follow any licensed-installer requirement in the manual or local code.

Is there a conversion kit in these listings?

Not for natural gas to propane. The Outland listing names a natural gas conversion kit as an accessory, which points from propane to natural gas.

What size tank do these pits use?

The Outland listing names a standard 20-pound cylinder, which is not included. The Ciays listing includes a tank holder but does not state a tank size.

Can I use either pit indoors?

Both listings are for outdoor use. Do not use a gas fire pit in a garage or enclosed space unless the manual allows it.

Does a propane pit burn smokeless?

The Outland listing describes a smokeless flame, and the Ciays bullets describe a smoke-free warmth. These are seller claims. A gas flame produces less smoke than a wood fire, but neither listing gives a measured figure.

Conclusion

To convert an existing natural gas pit, start with the manual and the manufacturer’s kit for your model. If no kit exists for it, a complete propane pit like the two listed here is the simpler route. Check the fuel type, BTU rating, hose and tank before you buy, and follow the manual for any gas work.
