FITTING CLEARANCE

CONNECTION REGULATOR & HOSE TO PIZZA OVEN

The regulator and hose are not assembled to the oven. Please make sure it is connected before use and is compliant with your country’s standards.

• Please always keep the gas bottle in an upright position.
• If the appliance is not in use, the gas must be turned OFF at the supply cylinder.
• The cylinder used must include a collar to protect the cylinder valve.
• The minimum distance between the appliance and the gas tank is 1 m.

CONNECTING THE GAS CYLINDER TO THE APPLIANCE

This appliance is only suitable for use with low-pressure butane or propane gas or LPG mixtures, fitted with the appropriate low-pressure regulator via a flexible hose. The hose should be secured to the regulator and the appliance with hose clips. Make sure the flexible hose does not come in contact with a hot surface and avoid twisting. Use a suitable regulator that is certified to BSEN 12864 or EN 16129. Make sure the regulator and flexible hose comply with local standards. Please consult your LPG dealer for information regarding a suitable regulator for the gas cylinder.

Natural Gas

The appliance must be installed by a competent gas installer. Conversion kit required. Gas conversion must only be carried out by a qualified and registered gas installer. Do not attempt conversion yourself.

Regulator & Hose

Use only regulators and hoses approved for LP Gas at the above pressures. The life expectancy of the regulator is estimated to be 2 years. The use of the wrong regulator or hose is unsafe; always check that you have the correct items before operating the appliance. The hose used must conform to the relevant standard for the country of use. Worn or damaged hose must be replaced. Ensure that the hose is not obstructed, kinked, or in contact with any part of the appliance other than at its connection.

For Flexible hose:

Avoid twisting the flexible tube when the appliance is in use. The length of the flexible hose shall not exceed 1.5 m. In Finland, the length shall not exceed 1.2 m. The hose should be certified according to the applicable EN standard and comply with local code.

Storage of Appliance

Storage of an appliance indoors is only permissible if the cylinder is disconnected and removed from the appliance. When the appliance is not used for a period of time, it should be stored in its original packaging and stored in a dry, dust-free environment.

Gas Cylinder

The gas cylinder should not be dropped or handled roughly. If the appliance is not in use, the cylinder must be disconnected. Replace the protective cap on the cylinder after disconnecting the cylinder from the appliance. The gas cylinder must be sited outside the body of the appliance.

Always connect or replace the cylinder in a well-ventilated area and away from any source of ignition, never in the presence of a flame, spark, or heat source. Cylinders must be stored outdoors in an upright position and out of the reach of children. The cylinder must never be stored where temperatures can reach over 50ºC. Do not store the cylinder near flames, pilot lights, or other sources of ignition. NO SMOKING.

This gas pizza oven is designed for use outdoors, away from any flammable materials. It is important that there are no overhead obstructions and that there is a minimum distance of 1 m from the side or rear of the appliance. It is important that the ventilation openings of the appliance are not obstructed. The appliance must be used on a level, stable surface. The appliance should be protected from direct draughts and shall be positioned or protected against direct penetration by any trickling water (e.g., rain).

Make sure that the gas cylinder compartment (if any) is not obstructed; keep it ventilated and clean. Parts sealed by the manufacturer or their agent must not be altered by the user. No modifications should be made to any part of this pizza oven, and repairs and maintenance should only be carried out by a registered service engineer.

Connection to Appliance

Before connecting the appliance, ensure that there is no debris in the gas cylinder valve, regulator, burner, or burner ports. A blocked burner may result in fire damage beneath the appliance. For the UK, the appliance is fitted with a push-fit connector. To connect, simply push the female end of the hose directly onto the male gas inlet valve on the appliance.

For Germany, Luxembourg, Austria, and Switzerland, the appliance is fitted with a G 1/4” left-hand (LH) threaded appliance connection. Ensure the correct connector is used for these markets. Attach the hose to the appliance and securely tighten it onto the threaded connection using a suitable spanner. If the hose is replaced, it must be securely fastened to both the appliance and regulator connections using appropriate hose clips. When the appliance is not in use, disconnect the regulator from the gas cylinder in accordance with the regulator manufacturer’s instructions.

For other EU countries, the gas hose connects directly to the appliance using the ribbed nozzle and clip as specified for the local market. To connect, warm up the hose end by submerging it in warm water. Ensure the hose is dry, then push it onto the nozzle, ensuring a good, tight fit. Complete the connection by securing it using the tightening clip provided.

NOTE – Appliances supplied with a 50 mbar nozzle for use in the following EU countries: Germany, Luxembourg, Austria, Switzerland, and the Slovak Republic. Only use the correct nozzle and regulator specified for your country and gas type. The appliance must only be used in a well-ventilated area. Do not obstruct the flow of combustion air to the burner during operation. THIS DUAL FUEL PIZZA OVEN IS FOR OUTDOOR USE ONLY.

BEFORE USE, CHECK FOR LEAKS

Never check for leaks with a naked flame; always use a soapy water solution.

To Check for Leaks

• Make leak-detecting fluid by adding one part washing-up liquid to 3 parts water.
• Ensure the control valve is “OFF”.
• Connect the regulator to the cylinder, and then turn on the gas supply.
• Brush the soapy solution onto the hose and all joints.
• If bubbles appear, you leak; turn off the gas supply at the gas cylinder immediately.
• Check the tightness of connections. If the leak cannot be stopped, do not try to repair. Call for replacement parts.
• Always turn off the gas at the cylinder after performing a leak test.

USER INSTRUCTIONS – GAS OPERATION

Before use, ensure that the oven and burner are free from blockages (e.g., food residue and insect nests – ants, bees, wasps, etc.). If an insect is found, they can be dangerous and must be cleaned out thoroughly. Please refer to the care of the oven for guidance. Should the appliance go out for any reason, no re-ignition should be attempted within 5 minutes. Always turn off the gas at the cylinder after performing a leak test.

Lighting Instructions (IMPORTANT)

From the OFF position, depress the control knob and hold it in for 10 seconds; this will allow gas to flow to the pilot. Turn the control knob anti-clockwise through the “Spark” decal to the “MIN” logo. The pilot should now light; if not, repeat the process. Continue to hold the control knob in for a further 10 seconds and release.

Turn on the main burner.

From the pilot position, turn the right-hand control knob to the large flame decal. The main burner should now light.

Adjusting Heat Setting

Leave the control knob set to the “MAX” decal.

Cook

After pre-heating, turn the knob to the Cook position; the oven will keep the best temperature to cook your pizza. Turn the control knob anti-clockwise to increase the flame height and thus the temperature setting. Turn the control knob clockwise to decrease the flame height and thus the temperature setting.

Turn OFF the burner

From any heat setting, turn the control knob fully clockwise to the “OFF” mark.

LIGHTING BY MATCH

1. Make sure the knob is in the “OFF” position.
2. Push down the knob and keep pressing whilst turning anti-clockwise to the “HIGH” position (a clicking sound is heard). Put the lit match near the ports of the burner; this will light the burner. Observe if the burner has lit. If not, repeat this process.
3. Adjust the heat by turning the knob to the High/Low position.
4. To turn the pizza oven ‘OFF’, turn the cylinder valve or regulator switch to the ‘OFF’ position and then turn the control knob on the appliance clockwise to the ‘OFF’ position.

WARNING: If the burner fails to ignite, turn the control knob off (clockwise) and also turn the cylinder valve off. Wait five minutes before attempting to relight with the ignition sequence. Before cooking for the first time, operate the pizza oven for about 15 minutes with the gas turned on LOW. This will “heat clean” the internal parts and dissipate odour from the painted finish.

USING WOOD

The Delivita Dual Fuel oven offers great flexibility, allowing you to cook using wood only or a combination of wood and gas to enhance flavour. Cooking with wood alone delivers a traditional, authentic wood-fired taste, while combining wood with gas allows you to introduce subtle smoky notes without relying entirely on wood as the heat source. This versatility lets you tailor both heat control and flavour to suit your cooking style.

When using wood only, it is strongly recommended to purchase the Wood Shelf accessory, which includes a protective cover designed to shield the gas burner from direct exposure to embers and ash. For combined wood and gas cooking, significantly less wood is required, as the primary heat is generated by the gas supply, with wood used mainly for flavour rather than sustained heat. In all cases, it is important not to overfill the oven with wood and to maintain a steady, controlled flame – this ensures efficient combustion, consistent temperatures, and optimal cooking performance.

LIGHTING & COOKING WITH WOOD

1. Once you have cured the oven, you’ll be ready to start cooking.
2. Place an eco fire-lighter towards the front/middle of the oven. Create a Jenga-like tower around the fire-lighter: position two pieces of kindling lengthways on either side of the fire-lighter; place the third piece on top and across the two pieces.
3. Light the eco fire-lighter and add a fourth piece of kindling on top of the existing kindling. Then add a small piece of hardwood, around 3 cm width on top of your tower.
4. After 10 minutes, the flame will have reached the top of the log. Add another small hardwood log. Nudge the logs together so they overlap one on top of the other and leave for approx. 20 minutes. TIP: Always allow airflow. If the wood is directly on the base with no embers underneath, the flame will go out, creating a lot of smoke.
5. The fire should now have taken. At this point, push the fire to the back of the oven slowly using the wire brush or the prodder. Add further wood to maintain the fire, but not exceeding two small logs at any one time.
6. Allow a further 7-10 minutes for the oven to reach its optimum temperature of 450°C to 550°C. Clean the cooking area using a metal wire brush, and you’re ready to go.

TIP: If the flame goes out and/or you have a lot of smoke coming out of the oven, ensure the log has airflow, then tear some bits from your eco lighter, position them onto the prodder, and light. Place the log on top of the oven; this will light the log and stop the excess smoke. Our Prod & Blow accessory can also help you re-ignite the flame by gently blowing down the pipe handle with the base directed at the embers.

SERVICING

Your pizza oven should be serviced annually by a competent registered person. Any modification of an appliance may be dangerous. If a replacement is necessary, please contact our Customer Service Department or your local dealer.

CLEANING & CARE

1. All cleaning and maintenance should be carried out when the pizza oven is cool and with the fuel supply turned “OFF” at the gas cylinder.
2. Store the pizza oven out of direct sunlight and indoors, where possible, when storing for extended periods of time. The pizza oven should not be exposed to harsh weather conditions such as snow, heavy rain, or strong winds.
3. Wait for the pizza oven to cool completely before moving.

Maintenance:

1. Keep appliance area clear and free from combustible materials, gasoline, and other flammable vapours and liquids;
2. Do not obstruct the flow of combustion and ventilation air;
3. Keep the ventilation opening(s) of the cylinder enclosure free and clear from debris;
4. Clean appliance, including special surfaces, with recommended cleaning agents, if necessary;
5. Check and clean the burner tubes for insects and insect nests. A clogged tube can lead to a fire beneath the appliance. Your pizza oven will look better and last longer if you keep it clean.

Care & Maintenance:

Apart from cleaning, your gas pizza oven is a fairly low-maintenance item. A couple of things are worth looking at, though. Remember to turn off and disconnect the gas before any maintenance is carried out.

1. If your gas pizza oven uses a flexible hose to connect to the gas, check the rubber O-ring on the regulator end of the hose assembly at least once a year. If it appears worn or cracked, have it replaced.
2. If you use a portable LPG gas cylinder, you will need to have the cylinder serviced or replaced every ten years. The date of the last service should be stamped on the neck of the bottle.
3. A rain cover is also recommended to cover your gas pizza oven and maintain and protect it from all weather conditions.
4. We recommend cleaning and maintaining the pizza oven monthly.
