OVEN INSTALLATION
IN THE EYES OF THE LAW, THE FLUE MUST SERVE ONLY ONE APPLIANCE.
CONNECTING MANY OVENS TO THE SAME FLUE COULD COMPROMISE A
REGULAR EVACUATION OF SMOKE.
Contact local re services to nd out about any restrictions
regarding ue installation or inspection of oven installation.
INDOOR FLUE CONNECTION
For the Napoli oven to function correctly, it needs a ue with a diameter
of 250 mm (10 in) and at least 4 metres (13 ft) high.
1. For existing and insufcient ues, it is advisable to use stainless steel
connecting pipes with right diameter and proper insulation.
2. Seal with materials resistant to high temperatures (450°C-840°F).
3. This connection must avoid as far as possible any bends or diversions
that can prevent the smoke evacuation.
4. Any bend must be no greater than 45 degrees.
5. To prevent smoke from travelling back into your home, place the
chimney pot in the highest part of the roof fully exposed to the wind
(anti-downdraught chimney cowls).
6. Do not connect the ue with other ducts.
7. The ue must be thermally insulated to prevent heat loss and to allow
the smoke to rise.
8. All installation work must be carried out by an authorized expert.
9. The following table shows the correct diameter (D) of the ue as its
height varies.
H < 3 m 3 m < H < 5 m H > 5 m
D 300 mm D 250 mm D 200 mm
N.B. A buttery valve, not included, can
improve the draught and smoke regulation.

15
PYROMETER
- The pyrometer detects the temperature at a
given point inside the oven. The value gauged
by the pyrometer is only indicative. With expe-
rience, you will better assess when the oven is
ready for various types of cooking. Gradually,
you will have command of your oven and beco-
me very adept at choosing the cooking tempe-
rature. The Alfa Pro laser thermometer comes as
an optional extra in the tool section of the web-
site.
OVEN DOOR
- If the re is too high and spills out of the oven
mouth, use the door to adjust the ame.
WARNING: this product has not been tested for
use with the door. To reduce the risk of re and
injuries, do not use the oven door.
Keep the oven door open when the re is on.
PUTTING OUT THE FIRE
To extinguish the re, close the oven door and wait for the ash to form. Make
sure the oven is cold and remove the ash with the help of metal tools.

16
WARNING: Before ring the oven, follow the instructions.
-Do not use ammable liquids or other fuels to light the re.
-Make sure that there are no ammable materials near the oven and that the
minimum safety distance is respected.
IGNITION
1. Make a small pile of dry kindling in the centre of
the oven.
2. When the re gets going, add two large logs and
move the re to one side of the oven.
3. After a few minutes of continuous burning, the
oven will reach the temperature of 400°C (750°F)
burning soot. Now the oven is ready to cook.
PUTTING OUT THE FIRE
-To extinguish the re, close the oven door and wait for ash to form
-After about 30 minutes, remove the ash.
DIFFERENT TYPES OF FIREWOOD
-Use small-sized dry wood for lighting the re.
-Never use treated, resinous or scrap wood to make the re.
-Wet or damp wood can pop due to the water trapped inside.
It will produce a lot of smoke and less heat.
IGNITION
WOOD-FIRED OVENS
FOR YOUR SAFETY:
-Do not leave the oven unattended while the re gets going
-To keep constant temperature, throw in small amounts of rewood at
regular intervals. Do not keep adding more logs to avoid a dangerous
rise in temperature or ames spilling out of the oven that could damage
people or things.
