FAQ
What does Ready to Finish mean on the Square Fire Pit Form?
It means the engineering is done and the aesthetics are yours. The Square Form arrives as a raw hardie board shell with the entire gas fire system included and fitted; your contractor applies tile, stone, stucco, or brick. You get a custom-built look without designing a fire system from zero.
Which sizes does the 16-inch-tall Square Form come in?
Five, per the spec tab: 36, 48, 60, 72, and 84 inches square (OPT-S36PB through OPT-S84PB), all at 16 inches tall. The 36-inch is patio-corner scale; the 84-inch square is a statement centerpiece with seating on all four sides.
What hardware ships inside?
The full working set: stainless steel drop-in pan, burner, key valve, whistle-free hoses, and stainless steel air vent, sized to your chosen Square Form. Whistle-free hoses matter more than they sound — they eliminate the hum cheap gas lines make at pressure.
Why choose the 16-inch height?
Low and social: at 16 inches the Square Form’s flame sits just below the sightline of seated guests, so conversation flows over the fire rather than around it. If you want a taller masonry presence or deeper skirt for finishing, its 24-inch sibling is the move.
Which ignition options come with the Square Form?
All five in the TOP lineup: Match Lit, Match Lit with Flame Sense (LC certified), Flame Sense with Spark, Low Voltage Electronic (CSA certified), and Plug and Play (CSA certified). The Square Form ships configured to your choice, propane or natural gas.
Is a square pit harder to veneer than a round one?
Easier, usually — the Square Form’s flat faces and clean corners take large-format tile and ledger stone with minimal cutting, which trims contractor hours. It is the shape most installers recommend when the budget favors materials over labor.
Can the finished fire pit get rained on?
Yes — stainless components and a masonry-veneered shell are built for weather. Let the pan dry before lighting after storms, and consider a cover to keep leaves out of the media. Compare finished-look options in our gas fire pit collection.
