Operation & Installation
SAFETY CONSIDERATIONS This appliance must be installed on a secure level base prior to use. WARNING: This appliance will become very hot, do not move it during operation. WARNING: Keep away from children and pets. The Dome unit and the burner must always be well ventilated. Do not move or leave Dome unattended whilst in use. Do not operate Dome in strong winds. Wind can extinguish flame. Do not spill or pour water onto the cooking floor. This is dangerous and 14 can crack the stone.
CARBON MONOXIDE Carbon Monoxide is a highly poisonous gas which can be produced when the device isn’t receiving enough ventilation. We therefore recommend using wood or gas fuels in a well ventilated area away from direct wind and to never cover the oven mouth when there is an open flame present. It is difficult to know if your device is producing Carbon Monoxide as it is an odourless and colourless gas.
This section details the set up of the oven and the accessories included with your Dome.
Set Up & Accessories
Moving the Oven The lifting straps located on the bottom of the oven are only suitable for single use. Please remove them once the oven is located to it's final location and use hand holds below. Do not move Dome whilst in operation or when it is still hot.
Never attempt to move the oven on your own. Two people should pick up the oven lifting from under the rounded ends of the oven, do not use the mouth of the oven as a lifting point. Remove anything loose on the oven before moving. Always plan the route you are going to take, remove any obstacles on your path and ensure the oven will fit through the intended route. Ensure the area you are moving the oven to fits with the guidelines on the following page.
732mm OVEN PLACEMENT When deciding where to place Dome ensure the area is large enough to accommodate the oven with 5cm around the base of the dock for air intake. It is important nothing is blocking the meshed panels as this will affect the performance of Dome. 630mm 660mm 488mm 226mm WARNING When placing your oven it is important to maintain proper clearances from combustible construction. Ensure Dome has 30cm clearance (back and sides) and 100cm clearance (front) from any combustible construction.
We recommend the height of the floor to be around the level of the bottom of the users elbow (usually around 120cm from the ground) Ensure the surface the oven is being placed on is completely level, stable and capable of easily holding the weight of the oven - 60kg. Floor Height WARNING Never operate the oven in high winds or if the wind is blowing into the oven mouth. Wind should be taken into consideration when choosing a location.
The flue is designed to have a rain guard which has a 5mm gap from the Dome. FLUE ASSEMBLY The rain cap prevents moisture from getting into the oven and should only be used when the oven is cooled and not in use.
STEAM PLUG The steam plug should always be inserted into Dome unless you are using the oven in conjunction with the steamer accessory. ASH TRAY Before firing the oven, make sure you have removed the ash tray and disposed of any packaging. The ash tray should always be inserted into its slot when the oven is in use. See the “Firing up wood” chapter for further details.

Firing Up Gas
Connecting to Gas Check that the gas you are using is specified on the data plate page. The gas cylinder used must have a safety collar to protect the valve assembly. Do not use a cylinder that is rusty, dented or has a damaged valve. We recommend using a 13kg gas bottle in conjunction with Dome. Connect the regulator to the gas canister, following the instructions for your regulator accordingly. Do not force the regulator as this could damage the gas bottle.
WARNING: If at any point you smell gas: Shut off the gas from the cylinder, turn off the switch on Dome and extinguish any open flames. 19 kg Capacity 5 kg If odour continues, move away from the Dome and gas supply then contact your gas supplier or fire service. Ensure that the LPG cylinder or regulator valve is closed. Do not store a spare LPG cylinder under or near this appliance.
Gas Safety Prior to use, check the oven, burner and venturi for blockages (e.g. food residue or insect nests - Wasps, Bees or Ants.) If an insect nest is found they can be dangerous and must be cleaned out thoroughly. Please refer to the cleaning and maintenance section for guidance. Should the appliance extinguish for any reason, turn off the control knob and the cylinder gas valve. Wait 5 minutes before attempting to relight the appliance. Some foods produce flammable fats and juices.
Keep the cylinder outdoors in its upright position. Make sure the flexible tube is not twisting when the appliance is in operation. Do not connect multiple gas canisters to Dome or store a spare within the same vicinity. A regulator which complies with EN16129 or EN12864 must fit between the gas canister and the oven. Do not position the gas canister under the oven. Never use a naked flame to check for gas leaks. Maximum length of hose cannot exceed 1.5m. In Finland, hose length cannot exceed 1.2m.
Indoor Use For indoor LPG or Natural gas installations a qualified gas engineer will need to be called to install the appliance to national and local legislation. It is important to service the oven extraction device regularly. Failure to do so may result in a fire. Contact your local professional ventilation company for more details.
PUCK CONFIGURATION (GAS) When firing the oven on gas you should have the burner guard over the burner and the stone puck covering the ash shoot.
INSTALLING THE IGNITER BATTERY Before using the gas burner for the first time you’ll need to install an AAA battery into the ignition module. To do this remove the rear panel on the dock to find the module. Unscrew the cap and place the battery in (negative end first). Replace the cap and panel and you're ready to connect the gas bottle to the oven.
CONNECTING THE GAS HOSE To attach the quick connection gas hose to your Dome pull the collar back on the connector and place the hose onto the gas inlet. When you release the collar it should return to its original position freely. This connection must be tested for leaks before using the oven.
PUSH FIT REGULATOR Make sure the lever is in the horizontal position so the button can be pressed. Pressing in the button, place the regulator onto the gas bottle. After releasing the button, turn the lever to a vertical position. This connection must be tested for leaks before using the oven. CLOCKWISE/ANTICLOCKWISE REGULATOR Ensure the gas bottle is turned off. Align the regulator and the gas bottle threads and carefully begin to tighten ensuring the threads aren’t crossed.
Testing For Leaks You should always check for gas leaks every time you disconnect and reconnect a gas fitting. Never ignite burners when leak checking. If there is a leak at the hose to oven connection, re-tighten the fitting with a spanner and check for leaks by applying a soap-and-water solution to the highlighted areas with a brush. If a leak persists turn off the gas and DO NOT OPERATE THE OVEN.
Pilot Light Ignition To ignite the pilot light press the control knob in until you hear a constant clicking sound. Then, still pressing, turn the knob 90˚ and hold it there until the pilot light is lit. You may not be able to see the naked flame but there should be clear reflections of it on the internal sides of the oven.
First Firing Only when you have a pilot light, turn the control dial anti-clockwise and the burner should light. On your first firing we highly recommend to put the burner on a medium to low flame for 30 minutes to help cure the oven before moving to a high flame. 30 Minutes Approx On subsequent firings after curing, you can bring the oven up to the desired temperature from ignition. If the oven has been dormant for an extended period, you should cure the oven again as if it was a first firing.
Gas Flame The flame should be yellow in colour and roll along the top of the oven.
Disconnecting Gas 3 Minutes PUSH FIT REGULATOR After cooking, be sure to turn off the gas from the gas canister first before turning of the Dome. This will allow any gas left in the burner or pipe to be used up safely. Three minutes after turning the gas off it will be safe to remove the regulator and turn the control dial back to the off position.
3 Minutes CLOCKWISE/ANTICLOCKWISE REGULATOR After cooking, be sure to turn off the gas from the gas canister first before turning of the Dome. This will allow any gas left in the burner or pipe to be used up safely. Three minutes after turning the gas off it will be safe to remove the regulator and turn the control dial back to the off position.
Maintenance CLEANING THE VENTURI If your burner’s flame is overly yellow or making more noise than usual you may have debris blocking the venturi. When the oven is turned off and cool, remove the maintenance hatch and use a vacuum cleaner with a long plastic nose to remove any debris. It’s good practice to check the inside of the dock for debris regularly.
This section details safety considerations and how to get the most from your oven when firing on wood.
Firing Up Wood
First Firing WARNING: Before lighting the oven, ensure you have adhered to the extraction specified in this manual. If you are unsure, do not use the oven. INTRODUCTION When firing the oven for the first time, it is important to slowly bring the oven up to temperature. This will help prevent thermal shock to the stone floor. WOOD SAFETY Do not use spirit or petrol for lighting or re-lighting! Use only fire-lighters complying to EN1860-3 or subsequent! Do not use treated or painted wood.
Wood To Use 140mm 20-50mm 20-50mm Wood is the most important factor when firing the oven on wood. It will determine the level of performance you will get from the oven. SIZE WOODS TO USE Smaller is better, we recommend using small pieces of kindling at 140mm by 20 - 50mm by 20 - 50mm. • • • • • • MOISTURE CONTENT 16% is the optimum moisture level for your wood, but anywhere between 10-20% is good.
Wood Fire Set Up When firing the oven on wood you should have the stone puck covering the burner hole and the mesh puck over the ash shoot.
Fire Starting 1x Natural Odour Free Firelighter 57
Moving The Fire 30 Minutes Approx Once the fire has established itself in the centre of the oven push it over to the left and continue to feed it for approximately 30 minutes or until the oven is fully saturated. Then move the fire to the right of the oven (over the mesh puck). and continuously add wood to the fire to keep a rolling flame across the top of the oven.
The flame from the wood fire should roll across the length of the oven’s roof. Avoid overfeeding the fire, there should never be flames coming out the mouth of the oven. If you are struggling to get a good flame, ensure the wood you are using follows our guidelines at the beginning of this chapter.
Ash Tray FLOOR TYPE AND TEMPERATURE Large rolling flames. Temperatures of 400˚C+ After moving the fire over the mesh puck turn the control dial on the ash tray to the fully open position. This allows more oxygen to get to the fire and will help you achieve a good rolling flame across the top of the oven. Always wear oven gloves when adjusting the dial on the ash tray. 60 Small flames. Temperatures of 250˚C - 350˚C Embers, fires died down.
FINISHED COOKING COOKING WITH WOOD TIPS Allow the fire to die down until there are no naked flames and only embers remain. The door can then be placed in the closed position to retain heat. For the best results and ease of cooking, be sure to use kiln dried wood with a moisture content of 20% or less. Standard logs (including kiln dried) should not be stored in a commercial kitchen.
ASH DISPOSAL Ensure you wait until the oven is cool before attempting to remove the ash. Don’t dispose of ash near or into anything flammable.
FUEL OVERLOADING CLEANING THE OVEN Overloading is dangerous and can cause excess smoke and flame. There should never be flames coming out the mouth of the oven, if this happens step away from the oven and wait for the fire to die down. The oven floor should reach temperatures of 343˚C to start “self-cleaning”. To do this raise the temperature of the oven to above 343˚C for a period of four hours.
Your guide to general maintenance.
General Maintenance
Cleaning The Oven INTERNAL The best way to clean the inside of the Dome is to burn off any food debris or soot that is left behind. When the oven is over 343˚C it will start self cleaning and any burnt on food will burn off after a period of four hours. If there is any soot or debris left, wait for the oven to cool down and use a soft brush to dislodge, being careful not to apply too much pressure and damage the oven. Use a vacuum cleaner with a plastic attachment to remove the loose debris from the oven.
EXTERNAL For the exterior of the oven use a non caustic bleach free cleaning spray on the dirty areas. Clean the area with warm soapy water and a sponge or non abrasive dish cloth and then wipe clean with paper towels. Avoid spraying directly onto the thermometer, control dial or meshed areas on the base of the oven. When the oven isn’t in use it should be kept under cover away from rain. If you are placing a cover directly on Dome, ensure it’s completely cooled down before covering.
Replacing The Probe Only when the oven is cold, remove the rear panel to access the probe terminal. The terminal is held with a magnet so can be removed from the dock easily to gain better access. Lift all the levers on the left hand side of the terminal to release the probe wires. Unscrew the probe from inside the oven and pull the old probe out the mouth of the oven.
Push the new probe's wires into the hole and feed them through until they are visible from inside the rear panel. Hand tighten the probe in place, avoid using a spanner as you may damage the probe. BEWARE: Don’t over tighten probe.
To wire the new probe, lift all the levers on the left hand side up and insert the wire into the holes on the side of the junction. The pattern/colour of the wire should match the corresponding wire on the opposite side of the junction. When the wire is fully inserted, push the lever back to its original position to clamp the wire in place. Ensure the wire is fully clamped in place before moving onto the next wire. Then reinsert the terminal into the dock and ensure the magnet engages with the metal plate.
Double check the probe is functioning by checking the digital temperature display and return the panel to the back of the oven.
