Pizza Oven Safety
Outdoor cooking is one of life's great pleasures — the crackle of a fire, the smell of wood smoke, and the satisfaction of pulling a perfectly charred pizza from a blazing oven. But like any high-heat appliance, your outdoor pizza comes with safety risks if set-up or used improperly.. A little preparation and the right habits go a long way toward keeping every cook fun, stress-free, and safe for everyone in your backyard.
Here's everything you need to know about outdoor pizza oven safety, from placement to post-cook cleanup.
Determining Safe Placement for Your Outdoor Oven
The ovens (both wood and gas) need plenty of airflow for proper combustion. Any gas-fueled oven (Hybrid, Gas, or Smart) MUST be installed with the proper accessories. If on a countertop, the ovens come with four feet that raise it off of the countertop by a minimum of 2 inches. This airflow is absolutely necessary for proper oxygenation to the burner for combustion.
Any wood-fired unit should also have the provided feet installed so that it has a minimum of 1/4 inch of airspace. All of Fontana's ovens have a clearance to combustibles of 1" of airspace. However, all units need a minimum of 3 feet from the exit of the chimney to a non combustible roof.
The short answer: Your outdoor pizza oven should be placed on a stable, non-combustible surface, at least 3 feet from the exit of the chimney and a one inch clearance to combustibles for the rear and sides.
Where you set up your oven matters more than most people realize. Before you fire it up for the first time, work through this checklist:
Surface & Stability
-
Place the oven on concrete, stone, brick, or a purpose-built outdoor kitchen structure
-
Avoid wooden decks without a proper protective barrier — wood can char or ignite under prolonged heat exposure
-
The surface must be level to prevent tipping
Clearances
-
Maintain at least 3 feet of clearance from overhangs, and structures
-
Overhead clearance is especially important — avoid placing ovens directly under low patio covers or pergolas without proper ventilation
-
Fontana ovens only need one inch clearance to combustibles for the rear and sides of the oven
Can you put an outdoor pizza oven under a patio cover? Yes, but only with adequate height (typically three feet) and open sides for ventilation. Enclosed or low-clearance patios can trap heat and smoke, creating a fire and health hazard. If you are burning wood the concern is more about discoloring your roof (vs a serious fire) If your wood has any moisture in it and starts smoking, you risk discoloring your overhead structure like a pergola.
Wind & Weather
-
Position the oven so the opening faces away from prevailing winds to avoid flare-ups and uneven heating
-
Keep your fuel — whether gas lines or wood storage — nearby but safely away from the heat source
Thinking about integrating your oven into a full outdoor kitchen? Fontana's Elysia modular outdoor kitchen system is designed with clearance and safety in mind, making it easy to build a beautiful, code-friendly cooking space.
What to Do If a Flare-Up Occurs
The short answer: Stay calm, keep the oven door open, and never use water on a grease fire inside a pizza oven. Most flare-ups are brief and self-contained.
Flare-ups happen — especially when roasting meats or cooking dishes with high fat content. Knowing what to do ahead of time makes all the difference.
Step-by-Step Flare-Up Protocol
-
Don't panic. Brief flare-ups inside the oven are normal and usually burn off quickly.
-
Leave the oven door open to allow oxygen flow — this helps the flame regulate naturally.
-
Do not use water. Water on a hot fire stone can cause cracking, and water on a grease fire can cause dangerous splattering.
-
Use a long-handled pizza peel to remove food if the flames are excessive.
-
Reduce your fuel source — lower the gas or stop adding wood until the fire settles.
-
Keep a Class K or ABC fire extinguisher nearby for grease fires. Never use a standard water extinguisher on a cooking fire.
Given that most flare-ups in the oven are self-contained you likely won’t need a fire extinguisher but it’s always good to have one for the grill or other fires.
Materials to keep on hand:
-
Long-handled pizza peel (keeps hands away from heat)
-
Heat-resistant gloves rated for high temperatures
-
ABC or Class K fire extinguisher
Post-Cook Safety: Cooling Down and Cleaning Up
The short answer: Wait at least 2–3 hours after cooking before attempting to clean your oven. The interior stones can retain heat for several hours after the flame is out.
Rushing the cool-down process is one of the most common — and preventable — safety mistakes.
After Every Cook
-
Turn off gas completely at the source, not just at the control knob
-
For wood-fired ovens, allow ash to cool fully before brushing it out of the oven
-
Keep children and pets away from the oven for at least 2–3 hours post-cook
-
Cover the oven only after it has fully cooled to prevent moisture buildup and warping
Cleaning the Oven Safely
-
Use a brass or stainless steel brush to clean the cooking stone — never use soap or water on a hot stone
-
Ash can be swept out with a small brush and metal dustpan once fully cooled
-
Wipe down the exterior with a damp cloth after it reaches ambient temperature
Ongoing Maintenance Tips
-
Inspect gas connections regularly for leaks
-
Check the door seal and hinges for wear
-
For wood-fired ovens, inspect for cracks in the dome or floor seasonally
Why Fontana Ovens Are the Safest Option on the Market
Not all outdoor ovens are built the same — and when it comes to safety, the difference in design really shows.
Is the outside of a pizza oven safe to touch? On most ovens, no — the exterior can reach dangerously high temperatures. Fontana ovens are different. Thanks to advanced multi-layer insulation, the exterior and roof of every Fontana oven stay cool to the touch during operation, making them significantly safer in family settings, especially around children.
Here's what sets Fontana apart from the competition:
Cool-Touch Exterior
Fontana's proprietary insulation keeps the outer shell safe to touch even when the interior is blazing at 900°F+. This is a major differentiator from most competing brands, where the exterior can reach burn-causing temperatures.
Low Clearance Requirements
Fontana ovens are engineered with some of the lowest clearance requirements in the industry at 1’ to combustible on the sides and rear, making them easier to install safely in a wider range of outdoor spaces.
App-Controlled Smart Ovens
Ever left a cookout wondering, "Did I actually turn the oven off?" Fontana's smart ovens (currently the Volta only) connect to a companion app, allowing you to monitor and control your oven remotely. No more second-guessing — and no need to run back outside.
Consistent, Predictable Heat
Digital temperature probes and smart controls (Volta only) mean you're not guessing at temperatures. Precise heat management reduces the risk of overheating and unexpected flare-ups.
Frequently Asked Questions
How far should a pizza oven be from a house?
At a minimum, keep your outdoor pizza oven at least 3 feet from any overhead structure. There is a one-inch clearance to combustible rear and sides. Always check your local fire codes, as requirements can vary by region.
Can you put an outdoor pizza oven under a patio cover?
Yes, with the right conditions. You'll need at least 3 feet of overhead clearance, open sides for ventilation, and ideally a non-combustible ceiling material. Enclosed patios without proper airflow are not safe for outdoor oven use.
Is it safe to use an outdoor pizza oven on a wooden deck?
It's not recommended without protection. If you must use a deck, place a non-combustible mat or stone slab beneath the oven to protect the wood from radiant heat. Always check with a fire safety professional before doing so.
Can I use an outdoor pizza oven in a garage?
No. Outdoor pizza ovens — whether gas or wood-fired — produce carbon monoxide and require open-air ventilation. Using one in an enclosed garage is a serious safety and health hazard.
Is the outside of a pizza oven safe to touch?
It depends on the brand. Most standard pizza ovens have exteriors that get dangerously hot. Fontana ovens feature advanced insulation that keeps the exterior cool to the touch — one of the key safety advantages that sets them apart from competitors.
