Natural Gas vs Liquid Propane: How Prism Ships Your Fire Feature
Every Prism gas fire feature is available in both liquid propane (LP) and natural gas (NG) configurations — but you choose at the ORDER stage, not after delivery. All burner systems are CSA-certified for outdoor installation. Here's what's involved in the fuel-type decision and whether you can convert later.

What you need
Step by step
Pick LP or NG at the ORDER stage
The burner orifice, air-mix, and regulator are configured at the factory for the fuel you specified. LP burners run at different pressure than NG burners — you can't just swap a propane tank onto a factory-NG unit and expect correct combustion.
Verify factory configuration on arrival
The data plate on the unit specifies the configured fuel. If the plate says NG and you ordered LP (or vice versa), do not install — contact your dealer immediately. Installing on the wrong fuel is a warranty-voiding event.
Confirm supply-side compatibility
LP installs typically run off a 20-lb or 100-lb tank (your installer confirms sizing based on BTU rating). NG installs require a plumbed line from your home gas meter with correct pressure — most home NG supply is 7" W.C. working pressure; your appliance may need a regulator step-down. Your installer specs this.
Know that conversion requires dealer service
If you move to a house with different fuel, don't DIY the conversion. Contact Prism (or the dealer) for the correct conversion kit — orifice, air-mix setting, and regulator all need to change together. A field conversion by a certified gas tech is possible on most Prism units; a DIY conversion voids coverage.
Common mistakes
- Ordering NG and planning to "just hook up a propane tank later". The orifice size won't match. Running LP through an NG orifice produces too-lean combustion and can damage the burner.
Hands-on tips
- Confirm your home's actual NG supply pressure with your utility before ordering an NG unit — some rural areas have lower pressure than the appliance's nominal spec.
- For LP installs, Prism recommends placing the tank at least 5 ft from the fire feature per most local codes. Confirm locally.
Questions people ask
Can I use a dual-fuel setup?
Not on the same burner. Prism's fire features are single-fuel at the appliance level. You can have one LP fire bowl and one NG fire bowl in the same backyard, but the burners themselves are single-source.
Do pool-rated units come in both LP and NG?
Yes — the pool rating is independent of fuel type. Pool Collection units ship in either LP or NG configuration.
