FAQ System baking ovens

• What should be considered during planning?

  Once a wood-fired oven is in place, it cannot easily be moved. That’s why the location should be carefully considered before construction. Such an oven is also a semi-open fireplace. It produces smoke and always poses a potential fire risk, which is why it should be positioned at a safe distance from the house or other buildings – while still being conveniently accessible. These and other planning aspects are taken into account by the stove builder, who will provide detailed advice.

• What needs to be considered from a legal perspective?

  A stone baking oven in the garden or courtyard requires approval, as it is considered a “stationary” structure that is not temporarily removed, for example during winter. If the wood-fired oven can be moved away at any time, no permit is needed because the unit does not fall under building regulations. However, neighborhood law requires consideration for others. If you build a small shelter around your wood-fired oven, for example as weather protection, this may not only require a building permit but also regular inspections by the chimney sweep.

  If you want to build without a permit, you must maintain a distance of three meters from the property line and/or public areas. In addition, the wood-fired oven must not exceed a certain volume or maximum height. These limits vary from one federal state to another. Information is provided by the district chimney sweep or the local building authority. If you live in a rented property, you should also inform the landlord or obtain permission. In some cases, the unit may have to be dismantled when moving out, which can be costly.

• How big should the wood-fired oven be?

  The size of the baking surface depends on what you want to prepare in the wood-fired oven – whether baking, cooking or roasting. A baking surface of 30 by 30 centimeters is perfect for one pizza, one tarte flambée or a loaf of bread. If the surface is doubled to 60 by 60 centimeters, there is enough space for four pizzas or tarte flambées or four to six loaves of bread. You can also comfortably fit several roasting pans, clay pots or pans.

• What do I need to consider when lighting the fire?

  To light the fire, place chopped firewood on top of crumpled newspaper and ignite it, then add larger logs. The dome will turn black at first – this is normal. Once the right temperature is reached, the soot will burn off again. The loading door should only be closed once only embers remain, as this further increases the temperature. After two to three burns and a maximum of seven kilograms of wood, the Grannus is hot enough. Grannus and the Fire Igloo guarantee culinary enjoyment in the open air.
