COMBUSTION SPEED

You can adjust the air control devices and grill to increase or
decrease combustion speed and therefore the heating or
cooking temperature:
• Fast combustion: primary air lever open (fully to right)
CLOSED OPEN (only for F80/F90 OPEN
to left);
• Slow combustion: primary air lever closed (fully to left)
CLOSED OPEN (only for F80/F90 primary air OPEN
CLOSED fully to right)
AVOID OVERLOADING THE APPLIANCE.
A relatively small and well oxygenated fire will burn better
and produce more heat than a large stack of wood blocking
the hearth.
IMPORTANT: during fast combustion make sure there is
no more than 2/2,5 kg of wood in the stove at all times.
A greater amount of fuel requires you to reduce the
combustion speed proportionally by closing the primary
air control and opening the secondary one. Adding more
fuel without changing the combustion speed will produce
thermal power greater than the cooker – environment
exchange capacity.
This will not only waste fuel but could also damage and
deform the appliance.
The ideal load for efficient and clean combustion
is 1,5 kg of wood per hour.
WARNING: Thermal shock caused by a sudden increase in
temperature can form cracks in the refractory bricks. These
cracks will not compromise the structure and resistance of
the bricks or cooker in any way.
When combustion has ended close all air lever and to
prevent the heat in the stove escapes with the flow of air
in the flue.
Lack of flue draught pressure. A column of cold air could
form in the flue pipe for a variety of reasons. These could be
low atmospheric pressure, humidity, strong winds or depres-
sion in the house (e.g. if the hood above your kitchen stove
is switched on).
In the event of low atmospheric pressure or rain, the flue
draught pressure will not be nearly as good as on a clear day
or during a cold, dry winter. Humidity can also form in the
flue pipe if the stove is not used for a long period of time.
It is worth keeping the stovés doors ajar to let air circulate
in the flue pipe.

3.2 USING THE OVEN

The oven always needs to be pre-heated for cooking. Add a
suitable amount of fuel to the combustion chamber, open
the primary air lever to obtain the required temperature.
Leave the fire to burn for about an hour with the primary air
valve open and then wait for about ten minutes after the
CLOSED fully
flames have died down in the combustion chamber.
Keep the temperature constant by adding thin wood to the
stove measuring about 3 cm in diameter at a rate of one or
two pieces every ten minutes.
DOMINO MODELS: oven chamber steam
release valve
On the right-hand side of the oven is a valve for releasing any
steam generated during the cooking phase. To operate the
valve, simply turn it with the poker.

3.3 USEFUL NOTES

COOKING PLATE
The cast iron cooking plate must never become incandescent.
Always use receptacles with flat heavy bases.
(for maintenance see chapter 4.2)
HEARTH GRILL
Poking the embers on the iron grille in the combustion
chamber will make the ash fall through into the ash drawer
below. This clears the way for the supply of primary air to the
combustion chamber – particularly important when starting
up your fire. combustion chamber – particularly important
when starting up your fire.
The slits in the grill have two specific functions: they let com-
bustion air pass through and, at the same time, enable the
disposal of the embers and ash.
The slits are wide enough to let through the ash and any
dead embers; while the walls of the slits are conical so as to
not block the flow of air.
INTERNAL ASH DRAWER
The ash drawer must be emptied on a regular basis to pre-
vent the iron grill from overheating.

THE GRILL MUST BE POSITIONED WITH THE NARROW
SIDE OF ITS SLITS FACING UPWARDS.
THERE MAY STILL BE SOME GLOWING EMBERS
IN WITH THE ASH.
