Cleaning the flue pipe. The flue pipe must be cleaned on an annual basis.
Air recovery
No air recovery. The stove can still be lit but soon burns up the available oxygen, reducing
combustion and causing the gases to build up and come out of the stove. The purity of the
ambient air is compromised as a result. In this case you definitely need an outside air vent.
Insufficient air recovery. If there is insufficient air recovery, combustion is poor and gases
will come out of the stove especially when you open the door to add more wood. If the stove
is installed in a room with double-framed doors or double-glazed windows, a suitable air vent
must be installed to ensure a good flow of air.
Other reasons
The position is too windy. You need to install a WINDPROOF chimney pot, otherwise any
change in the direction of the wind will compromise evacuation of the gases.
Presence of two flue pipes in the same room or in two adjacent rooms. The flue pipe with the
more powerful draught pressure will draw the gases from the one with the least powerful
one; as a result gases will come out of the stove with the poorer flue draught pressure.
Presence of a ventilating hood in the room. The ventilating hood is normally designed to
evacuate 300/400 cubic metres of air per hour. If there is insufficient air recovery, the air will
be retrieved by the stove causing smoke.
If you switch on the hood while the stove is in use, you must leave a window ajar for all the
time the ventilating hood is in operation.
Poor connections. Narrow sections, internal edges, imperfect joints and sharp bends might
accidentally be created when connecting the stove to the flue that could impede the
evacuation of the gases.
Uninsulated flue pipe. Gases passing through an uninsulated flue pipe will cool down and
compromise flue draught pressure. This causes atmospheric pollution, condensation and the
deposit of unburned products inside the pipe, affecting its efficiency.
Note: an uninsulated flue pipe causes the gases to cool down by 30 to 50°C per linear metre.
5 . MAINTENANCE
5.1 ROUTINE CLEANING AND CHECKS
The cooker is at its most efficient when all the surfaces and pipes the gases come in contact
with are kept perfectly clean. We advise regular maintenance by a qualified technician.
All maintenance and cleaning must only ever be carried out when the stove has fully cooled
down:
a) Remove the iron cooking plate and clean underneath thoroughly with a brush
b) Remove the pressurized door under the oven and use the small shovel to clean the flue-
ways, removing all the ash at the base
c) “Rustica” models: the pressurized door is removed by undoing its two retainer screws and
removing the oven door by opening and turning the safety catches 180°.
d) F6000 model: the flue gas pass under the oven is cleaned by removing the iron plate at
the base of the oven; be careful not to damage the fibre-glass seal when you put the
plate back again.
e) DOMINO models: the flue gas pass is cleaned as above; the part above the oven, instead,
is accessed by removing the closures under the ash drawer.
f) Clean all accessible areas.
Cleaning the ceramic glass of the combustion chamber’s door
Eliminate all traces of soot on the inner side of the ceramic glass using a soft cloth dampened
with a little clean ash, or with a suitable product in the event of stubborn traces of tar. Dry
well afterwards.
Clean the outer side of the ceramic glass with a damp cloth or, if necessary, with a little
neutral detergent. Dry well afterwards.
