B) ASSEMBLY, USE AND MAINTENANCE OF THE OVEN
1. Lay the support top with ceramic fi bre (or equivalent), capable of withstanding a temperature of at
least 500 ° C.
2. Set the components of the base on the ceramic fi bre. Following the numbering shown here, (see
numbered exploded view) proceed with the components which make up the dome. The components
of the oven, in refractory material expand with heat. Therefore they must be held together only by
steel wire. Do not glue or seal these components together.
3. The components of the oven must be insulated in order to achieve better heat results. This opera-
tion must be completed prior to assembling the other components of the Barbecue. It is advisable to
cover the external part of the oven with a layer of at least 5 cm of insulating material like ceramic fi bre
(or DIN 4102 A1 mineral wool ). The insulation must also be secured by means of steel wire. Do not
insulate with sand, salt or ash.
4. The ovens are complete with a smoke valve placed on the dome or on the connection. Seal the joint
with glue type
SUNDAY® BETONFAST®.
5. Once the oven and cladding have been assembled we recommend building a series of small fi res to
drive out any traces of humidity in the single components, thus avoiding possible breakage. Humidity,
especially on fi rst ignition, can cause the formation of black smoke.
6. Check that the oven draws well: burn some paper inside the oven and check that the fl ame is drawn
towards the smoke outlet.
7. The oven is ready for use when the internal surface becomes white. The formation of small black
incrustations indicates that the oven is still cold, and not yet ready for cooking.
8. Always start a fi re slowly and add wood gradually.
9. We recommend the use of dry, good quality, small cut wood with humidity inferior to 20%.
10. Micro fi ssures due to manufacturing or thermal dilation are typical characteristics of refractory pro-
ducts and do not jeopardise their stability, lifespan and functionality.
11. Do not put the fi re out by throwing water on it.
12. Always use an insulating glove when using the oven.
13. It is advisable to perform the fi rst ignition without any food followed by a series of brief ignitions (at
least 3), using MAX 3.5 kg per ignition.
14. The temperature inside the oven must not exceed 350 °C ; open the oven door to rapidly reduce the
temperature.
15. In order to regulate the input of combustion air, move the door forward or backwards.
16. Periodically check that there are no cracks in the cladding as these can cause water leaks which will
dampen the insulation and compromise the correct use of the oven.
There are two ways in which the single chamber refractory oven can be used both for combustion and
cooking:
a) Indirect radiation cooking: heat up the oven until reaching the desired temperature. Remove the em-
bers. Introduce the food. This cooking mode is suitable for baking bread or biscuits.
b) Direct radiation cooking: the embers remain inside the oven and can be kept burning to maintain the
high temperature. Cooking mode suitable for pizza, roasted and grilled meat or fi sh.
