A gas outdoor fireplace burns propane or natural gas inside a masonry, steel or cast surround, giving a patio or deck the look of a hearth without hauling wood or sweeping ash. We have not used these products ourselves, so this page does not rank anything by personal experience. It lays out the features that separate one fireplace from another, so you can read a listing with a clear checklist in hand.
The main choices are the fuel the unit is built for, the heat output the maker claims, how the flame is lit, and how the body is made and finished. Local codes and the maker’s manual govern placement, clearances and connections, so use this guide to compare features and not as a promise about any single model.

What to Look For
| Factor | Why it matters | What to check |
|---|---|---|
| Fuel type | Decides whether you need a tank or a fixed gas line | Propane, natural gas or convertible, and whether a conversion kit is listed as included |
| Heat output | Gives a rough idea of how large an area the flame can warm | The maker’s stated output figure compared with the size of your seating area |
| Ignition | Affects how easily and reliably you light the flame | Electronic push button, match lit or remote control, and what power source it needs |
| Build and finish | Sets how well it handles sun, rain and temperature swings | Material of the shell and burner, coating type and the maker’s care notes |
| Size and clearance | Determines where it fits and how it sits near walls | Listed footprint, height, weight and the clearances the manual calls for |
| Weather protection | Helps the unit last through the off season | Whether a fitted cover is included or sold separately |
Setup and Care Tips
- Read the manual in full before the first use, including its notes on gas connections and clearances.
- Place the fireplace on a level, non-combustible surface in the open air, as the maker directs.
- Have a qualified installer handle any fixed gas line work and check local rules first.
- Wipe the surround and burner area with the cleaning method the maker suggests, and keep vents clear of debris.
- Cover the unit when it is not in use and close the gas supply before storing it for the season.
Mistakes to Avoid
- Choosing by looks alone without checking the heat output and the size of your seating area.
- Ignoring the fuel type and discovering later that a gas line or tank swap is needed.
- Overlooking the clearances and surface requirements listed in the manual.
- Skipping the cover and leaving the burner exposed to rain and leaves all winter.
- Assuming a conversion kit is included when the listing does not say so.
FAQ
Propane or natural gas?
Propane gives you freedom to place the unit anywhere a tank can go, while natural gas suits a spot near an existing line and removes the need to swap tanks. Some models can switch fuel with a kit, so read the listing closely for what is included.
How big should the fireplace be?
Think about how many people will sit around it and how much space the patio offers. A larger body gives a broader flame display and more presence, while a compact one fits tighter corners. Always compare the footprint with the clearances in the manual.
The Short Version
Match the fuel type to your setup, compare the maker’s stated heat output with your seating area, check the ignition style and materials, and plan for a cover. Follow the manual and local codes for placement.
