Heating Principles

The Forno oven employs three primary heat sources to achieve optimal cooking temperatures:

• Radiant Heat: Direct heat from the flame or hot dome walls cooks the top of the pizza.
• Convection Heat: Hot air circulates within the oven chamber, cooking the sides and ensuring even heat distribution.
• Conduction Heat: Direct heat transfer from the hot refractory hearth stone to the bottom of the pizza, creating a crispy crust.

4. Setup

4.1 Unpacking and Inspection

1. Carefully remove all packaging materials.
2. Inspect the oven and cart for any shipping damage. Report any damage to your retailer immediately.
3. Ensure all components listed in the packing list are present.

4.2 Choosing a Location

• Place the oven on a level, stable, non-combustible surface.
• Ensure adequate clearance from combustible materials (e.g., walls, fences, trees). Consult local fire codes for specific requirements. A minimum of 3 feet (0.9 meters) from sides and back is generally recommended.
• Ensure the area is well-ventilated and not under any overhead combustible construction.

4.3 Cart Assembly (if required)

The oven typically comes pre-mounted on the cart. If assembly is required, follow the separate cart assembly instructions provided with the unit. Ensure all bolts are securely tightened.

4.4 Gas Connection (Natural Gas)

IMPORTANT: Gas connections must be performed by a qualified gas installer or service agency in accordance with all local codes and regulations.

1. Ensure the main gas supply valve is OFF.
2. Connect the oven's gas inlet to your natural gas supply line using appropriate fittings and a flexible gas hose (if applicable).
3. Perform a leak test: Turn on the gas supply. Apply a soapy water solution to all connections. Bubbles indicate a leak. If a leak is detected, turn off the gas, tighten connections, and retest. Do not operate the oven if a leak persists.

4.5 Initial Burn-In (Curing)

Before cooking food, the oven's refractory materials must be cured. This process removes moisture and strengthens the oven. Perform a slow burn-in over several hours:

1. Start with a small, low gas flame or a very small wood fire for 1-2 hours.
2. Gradually increase the heat over the next 2-3 hours, allowing the oven to reach medium temperatures.
3. Finally, bring the oven to full operating temperature for about an hour.
4. Allow the oven to cool completely. This process should be done once.

During the curing process, some smoke or steam may be visible, which is normal. Ensure good ventilation.

5. Operating Instructions

5.1 Gas Operation

1. Ensure the gas supply valve is open.
2. Locate the electronic ignition switch and gas control knob.
3. Push and turn the gas control knob to the 'PILOT' position. Press and hold the ignition button until the pilot flame ignites. Continue holding for 10-15 seconds to allow the thermocouple to heat up.
4. Once the pilot is stable, turn the control knob to the desired temperature setting. The main burner should ignite.
5. Allow the oven to preheat for 30-60 minutes, or until the hearth reaches the desired cooking temperature (typically 700-900°F / 370-480°C for pizza).
6. To shut down, turn the gas control knob to the 'OFF' position and close the main gas supply valve.

5.2 Wood Operation

For wood-fired cooking, the gas burner can be off or used to assist in initial heating.

• Wood Selection: Use only seasoned hardwoods such as oak, maple, or fruitwoods. Avoid softwoods, treated wood, or wood containing resins, as these can produce excessive smoke and creosote.
• Starting the Fire: Place a small amount of kindling and a fire starter (no lighter fluid) at the back or side of the oven chamber. Light the kindling.
• Building the Fire: Gradually add small pieces of wood as the fire grows. Aim for a consistent flame that rolls across the top of the oven dome.
• Preheating: Allow the oven to preheat for 60-90 minutes, or until the dome and hearth are glowing white and the temperature reaches 700-900°F (370-480°C).
• Maintaining Heat: Push the burning embers to the side or back of the oven. Add small pieces of wood as needed to maintain temperature.

5.3 Dual Fuel Operation

You can use both gas and wood simultaneously. The gas burner can provide a consistent base heat, while wood adds flavor and higher temperatures. Ignite the gas burner first, then introduce wood as described above.

5.4 Cooking

1. Once the oven is preheated to the desired temperature, use a pizza peel to place your pizza directly onto the hot hearth stone.
2. Monitor the pizza closely. Pizza cooks very quickly in a high-temperature oven (often 60-120 seconds).
3. Rotate the pizza periodically with the peel to ensure even cooking and browning.
4. Remove the pizza when the crust is golden brown and the cheese is melted and bubbly.

6. Maintenance

6.1 Cleaning the Hearth and Interior

• After the oven has cooled completely, use a brass-bristle brush to scrape any food residue from the hearth stone.
• Use a small shovel or ash scoop to remove ash and debris from the oven chamber.
• Do not use water or chemical cleaners on the refractory surfaces, as they can damage the material. The high heat of the oven naturally sanitizes the cooking surface.

6.2 Ash Removal (Wood Fired)

Regularly remove ash from the oven. Ensure ashes are completely cold before disposal. Place them in a metal container with a tight-fitting lid, away from combustible materials.

6.3 Exterior Cleaning

Clean the stainless steel and glass tile exterior with a mild soap and water solution and a soft cloth. Avoid abrasive cleaners that could scratch the surfaces.

6.4 Gas System Inspection

Periodically inspect the gas hose, regulator (if applicable), and connections for signs of wear, damage, or leaks. Replace any damaged components immediately. Have the gas burner and lines inspected annually by a qualified technician.

6.5 Winterization

In colder climates, it is recommended to cover the oven with a weather-resistant cover when not in use, especially during winter months, to protect it from moisture and freezing temperatures.
