Arc Lite Replacement Stone: When and How to Swap It

Learn when your Arc Lite stone truly needs replacing and follow a safe, step-by-step swap process, including the tools and checks that prevent damage.
Quick answer
Replace the Arc Lite stone only when it is cracked through, deeply pitted, or no longer sits flat in the oven. The swap itself takes about ten minutes: let the oven cool completely, remove the old stone, drop in the replacement, and use the included adjustment tool to level it. Most surface discoloration is normal and does not require a new stone.
Signs the stone actually needs replacing
Not every mark on a pizza stone means it is finished. Dark patches, light scorching, and a chalky surface are typical after repeated high-heat baking and do not affect performance. A true replacement is needed when the stone has a crack that runs through its thickness, when a corner has chipped away so the surface no longer sits flush, or when the stone has warped enough that a pizza rocks on it. If the stone still lies flat and holds heat evenly, keep using it.
- Crack that goes all the way through the stone
- Chipped or crumbling edges that change how it sits
- Visible warp or wobble when you press the center
- Deep pits that catch dough and make launching difficult
What the Arc Lite replacement kit includes
The Arc Lite Replacement Stone is sold as a kit, not just a bare stone. It contains the stone itself, a stone adjustment tool, a landing bay protective screen, and protective gloves. Those extras matter because the stone must be leveled correctly after installation, and the screen and gloves help you handle hot or sharp edges safely. The kit is intended for Arc Lite ovens only. If your stone is fine but your gas connection is damaged, you would need the Arc Lite Gas Hose and Regulator - US instead, which is also Arc Lite-specific.
Before you start: cool, clear, and check the manual
Never attempt a stone swap while the oven is warm. The stone holds heat for a long time, and the gloves in the kit are not a substitute for a fully cooled oven. Once cool, remove the oven door or any accessory that blocks the stone, and work on a stable surface. The kit's instructions refer you to the product manual for your specific oven; check it before forcing anything, because the Arc Lite stone sits in a shaped cradle and may need to be lifted at a slight angle rather than pulled straight up.
Step-by-step Arc Lite stone swap
- 1. Cool the oven completely: Turn off the gas, close the valve, and wait until the oven is cold to the touch. Do not rely on the gloves to handle a warm stone. Checkpoint: the stone should feel room temperature before you touch it.
- 2. Remove the old stone: Open the oven and lift the stone out of its cradle. If it resists, check the manual for the correct angle; do not pry it with metal tools. Common mistake: forcing a stuck stone and cracking the new one during installation.
- 3. Clean the stone cradle: Brush out any ash, crumbs, or debris from the base of the oven where the stone sits. A clean cradle helps the new stone sit flat. Checkpoint: no loose grit remains under the stone area.
- 4. Seat the replacement stone: Lower the new stone into the cradle, following the manual's orientation. It should drop in without rocking. Common mistake: setting the stone in at an angle so one corner sits high.
- 5. Level with the adjustment tool: Use the stone adjustment tool from the kit to fine-tune the stone's position until it is flush and stable. Checkpoint: press gently on each corner; there should be no movement.
- 6. Reinstall the landing bay screen: Fit the protective screen from the kit according to the manual. This helps shield the stone edge during loading and unloading. Common mistake: leaving the screen out, which exposes the stone edge to knocks.
- 7. Run a short heat cycle: Fire the oven for 15–20 minutes on a moderate setting to drive off any moisture and settle the stone. Let it cool again before your first pizza. Checkpoint: no cracking or shifting sounds during the first heat-up.
Arc Lite spare parts that pair with this job
- Arc Lite Replacement Stone: Kit to replace the stone in an Arc Lite. Includes stone, stone adjustment tool, landing bay protective screen and protective gloves. You get the leveling tool and safety gear in the same box, so you do not need to source them separately.
- Arc Lite Gas Hose and Regulator - US: Arc Lite Gas Hose with 30mbar screw fit adaptor for connection to a standard US propane tank. Note this is for Arc Lite ONLY and cannot be used with other Gozney ovens. If your stone is fine but the hose or regulator is worn, this is the correct replacement for an Arc Lite in the US; it will not fit other Gozney models.
- Tread Venture Stand - Leg Replacement Kit: Kit of 4 x replacement legs for Tread stand. This is a stand part, not an oven part, so it is only relevant if you also own a Tread stand and its legs are damaged.
