INSTRUCTIONS FOR THE
INSTALLER
2.1. Warning to installers
All local and national regulations,
including all those referring to national and
European standards, must be observed
when installing the appliance.
Installation of the appliance must be
performed by an authorised installer.
An incorrectly installed appliance may
lead to serious incidents (fires, creation of
harmful gases, deterioration of nearby
fixtures, etc.).
Lacunza’s liability is limited to the
supply of the material and does not include
installation of the appliance.
2.2. Room for installation
2.2.1. Ventilation of the room
The appliance needs to consume
oxygen (air) in order to work properly.
Ensure a suitable air supply in the room in
which the appliance is fitted. This quantity
of oxygen is additional to the oxygen that
we need in order to breathe (air renewal).
In order to ensure the high quality of
the air you breathe and to avoid potential
accidents resulting from high
concentrations of the gases produced by
combustion (mainly carbon dioxide and
carbon monoxide), it is absolutely crucial to
ensure the suitable renewal of the air in
the room in which the appliance is fitted.
the room must always have at least two
permanent grilles or openings to the
exterior in order to renew the air (one for
intake and the other for extraction).
For the installation of its appliances,
Lacunza recommends an additional section
for these openings. One of these two grilles
must be situated high up in the room (at
less than 30 cm from the ceiling) and the
other one low down (at less than 30 cm
from the floor). Both grilles must open
outdoors in order to renew the air in the
room with fresh air.
The minimum section that each of these
grilles must have depends on the nominal
output of the appliance in accordance with
the following table:
Figure No.4 - Guideline indications for
ventilation grilles
In the case of appliances on which it is
possible to pipe combustion air in from
outdoors, the specifications described in
the Table above are not necessary.
The appliance must always be used with
the door(s) closed.
In rooms equipped with Controlled
Mechanical Ventilation, the system
extracts and renews the ambient air; in
such cases, the room is at slightly low

pressure and it is necessary to install a non-
closable outside-air inlet with a section of
at least 90 cm².
2.2.2. Location of the appliance in the
room
Choose a location in the room which
favours good hot-air distribution by
convection and radiation.
The appliance comes with wheels to
help move it into position. In order to
move it, it is necessary to make sure that
the support legs are raised by turning them
with the aid of a spanner. Once in position,
lower the legs until the appliance is at the
desired height.
2.3. Installation of the appliance
2.3.1. Floor
Make sure that the base can withstand
the total constructed weight of the
appliance and its casing.
When the floor surface (base) is
combustible, fit suitable insulation.
2.3.2. Safety distances
Be sure to respect the appliance
installation distances from combustible
materials. Looking at the appliance head-

Bear in mind that it may even be
necessary to protect non-combustible
material in order to prevent breakage,
deformation, etc., as a result of
overheating if the non-combustible
material is not designed to withstand high
temperatures.
2.3.3. Checks before lighting for the first
time
•Make sure that the glass/es is/are
not broken or damaged.
•Make sure that the flueway is not
obstructed with packing or loose parts.
•Make sure that the airtight joints
on the flue circuit are in perfect
condition.
•Make sure that the doors close
properly.
•Make sure that all moving parts are
fitted in place.
•Check that the two deflectors are
fitted properly; the lower deflector has
four positions with which to open or
close the flue to a greater or lesser
extent. On the NON-BASIC version of
Itaca, make sure that the flue damper
flapper valve works properly. When the
guillotine door is raised, the flapper
rotates to allow for greater smoke
evacuation to avoid smoke entering the
room. When the door is closed, the
flapper returns to its horizontal
position, acting as a flue damper.
•Remove the bolts securing the
counterweights before trying to close
the guillotine door: when you remove
ITACA fireplace models from their
packaging, you will see that the door is
open at its highest position and cannot
be lowered. This is because the
counterweights are secured with M6
bolts on the 2 front legs at the bottom
of the appliance so that they do not
swing and damage the appliance during
transportation. Do not try to move the
door before removing the bolts that
secure the counterweights

INSTRUCTIONS FOR THE INSTALLER 8
2.
IMPORTANT: Remove the nut and bolt on
each side of the appliance before lowering
the guillotine door
Figure No.5 - Access to remove the bolts
securing the counterweights
2.3.4. Height adjustment and levelling the
appliance
The appliance must be perfectly level,
horizontally and vertically, both at the
front and on the sides (use a spirit level).
The appliance has adjustable legs with
which to adjust its height.
IMPORTANT! When it is level and
before encasing the appliance, check that
the guillotine door works properly; the
door rises and lowers smoothly and
without any friction or noise other than
that of correct operation of the guillotine
system.
2.3.5. Casing
Make sure that the material around the
appliance is not flammable or likely to
deteriorate as a result of heat (wallpaper,
carpet, plastic-based casing, Silestone,
etc.).
The image below gives an example of
how the appliance can be encased
properly:

2 Flue
3 Incombustible material (Inner hood
insulation)

incombustible material
5 Wall
6 Fresh-air inlet (1,000 cm2)
7 Hot-air outlet (1,000 cm2)

INSTRUCTIONS FOR THE INSTALLER 9
2.
Figure No.7 - Exterior diagram of the casing
In order to enable suitable air
circulation and correct operation, the
casing must have a fresh-air inlet with a
minimum section of 1,000cm2beneath the
level of the actual appliance and a hot-air
outlet measuring at least 1,000cm2above it
(just before the insulating deflector inside
the casing). These inlet and outlet sections
must ensure air renewal in such a way as to
avoid damage to parts inside the hood due
to excess temperature.
This specification must be observed
regardless of the type of installation
chosen (with or without forced ventilation,
combustion air from indoors or outdoors,
directed hot-air outlets with or without
pipes, etc.). A further hot-air ventilation
grille is also recommended between the
insulating deflector on the hood and the
ceiling.
Warning: on appliances on which it is
possible to pipe air to the firebox, the hood
requires a further air inlet at the bottom, in
addition to the 1,000cm2inlet, if the air
supply comes from the room in which the
appliance is fitted.
On non-central-heating appliances
(without back boiler), Lacunza does not
recommend enveloping the outside of
appliances with insulation.
The installer must fit the necessary
inspection accesses (trap doors, hatches,
etc.) so that everything inside the hood
that may need maintenance work or
replacement can be accessed at any time,
e.g. counterweight system, hydraulic
components, heating circuit safety
components.
2.3.6. Connection to the flue
The appliance must be connected to the
chimney flue using special piping designed
to resist the products of combustion (e.g.
stainless steel, enamelled steel, etc.).
To connect the flue to the socket flange,
insert the piping inside the flange and seal
the joint with fire sealant or fire cement to
make it completely airtight.
The installer must ensure that the pipe
connected to the appliance is well secured
and there is no chance of it coming free
from its housing (e.g. as a result of
dilatation due to temperature, etc.).
2.3.7. Piping air to other rooms
It is possible to pipe some of the heat
generated to other rooms in the house
using the appliance. This does not mean
that the appliance works more efficiently,
but it does mean that the heat it creates is
distributed better. For this purpose, in the
top surface of the appliance there are 4
potential hot-air outlets with diameters of
120mm on the top shell of the appliance.
Pipes can be fitted from these outlets to
other rooms. If you intend to do this, bear
the following points in mind.
•The air ducts must always be heat
insulated and smooth inside (not
corrugated).

INSTRUCTIONS FOR THE INSTALLER 10
2.
•The pipes must always have an
upward slant to facilitate movement by
air density.
•On routes with a lot of load loss (a
lot of retention), air movement can be
forced along the ducts using a motor or
fan, provided that it is designed to
withstand such temperature conditions.
Bear in mind that air ducts mean that
noise travels more easily from one room to
another.
The following table shows the heat
output of the air from the hot-air outlets

Figure No.8 - Table showing heat output of the
air leaving the appliance
Note: The values shown in the above
table were measured at the appliance
output point and based on tests performed
at nominal heat output and maximum fan
speed.
All hot-air ducts lose heat, meaning that
the heat output obtained at the end of
piping always depends on its design.
2.3.8. Piping air to the firebox
On this model, it is possible to pipe air
to the appliance for combustion straight
from outdoors. We recommend that, if
possible, air be drawn from outdoors for
combustion via a non-closable pipe with a
diameter of 120mm leading to the nozzle
on the bottom-front of the appliance. This
is the best option because it means that
draughts are not created in and oxygen is
not consumed from the room in which the
appliance is fitted. A further advantage is
that there is no danger of downdraught
which may hinder the correct updraught of
the appliance when an extractor or
mechanical ventilation appliance is used in
the same room as the central-heating
appliance or in another one alongside it.
If this is not possible, ensure that the
appliance receives air for combustion via
the relevant grille at the bottom of the
hood (in addition to the hood ventilation
grilles).
2.3.8.1. Combustion-air intake and hot-air
output installation options
Different installation systems need to
be borne in mind depending on the source
of combustion air (air from outdoors or
from inside the room in which the
appliance is fitted) and the hot-air output
system (air output by natural convection or
by forced convection involving a fan) to
ensure that ITACA-INCA appliances work
properly. There now follows a description
and image of each of these options:

Key to combustion-air intake and hot-air
output installation option diagrams:
1 Hot-air output grille
2 Combustion-air intake grille
3 piping
4 Combustion-air intake nozzle
5 Combustion-air intake from outdoors
OPTION A: Combustion-air intake from
inside the room and hot-air output by
natural convection (without fan).
With this option, it is not necessary to
lead the hot air along piping to the hot-air
output grilles, as shown in the image, or
from the combustion-air intake grille to the
combustion-air nozzle that feeds
combustion air to the firebox.
Figure No.9 - Image showing Option A
OPTION B: Combustion-air intake from
inside the room and hot-air output by
forced convection (with fan).
With this option, the hot air can be led
along piping from the hot-air output
nozzles on the appliance to the hot-air
output grilles on the casing or to other
rooms. The air flow required at any given
time can also be regulated via the
potentiometer on the fan. Up to 4 outputs
can be fitted (the nozzles not to be used
should be capped). In such cases, the
combustion-air intake must be led via
piping from the grille on the outside of the
casing to the combustion-air intake nozzle
so that it does not interfere with the air
drawn in by the fan.
Figure No.10 - Image showing Option B
OPTION C: Combustion-air intake from
outside the room and hot-air output by
natural convection (without fan).
With this option, the combustion-air
intake is led from outside the room in
which the appliance is fitted (other room
or outdoors) to the combustion-air intake
nozzle via piping with a diameter of
120mm and it is not necessary to lead the
hot air coming out of the nozzle on top of
the appliance to the hot-air output grilles
on the casing with piping.

INSTRUCTIONS FOR THE INSTALLER 12
2.
Figure No.11 - Image showing Option C
OPTION D: Combustion-air intake from
outside the room and hot-air output by
forced convection (with fan).
The installation system for this option is
the same as that of the previous option,
but also involves leading the hot-air output
from the nozzles on top to the hot-air
output grilles or to other adjoining rooms
via piping with a diameter of 120mm. The
nozzles on top of the appliance not to be
used should be capped.
Figure No.12 - Image showing Option D
WARNING!: When the appliance has a
fan (C/V option), it is important that the
shell is well ventilated through both the
upper and lower grilles on the casing.
Respect the minimum sections
recommended for the grilles (larger grilles
are no problem); otherwise, overheating
problems may arise inside the shell and
excess air temperatures may cause the fan
to stop by triggering its overload safety
system (in this case, due to excess
temperature).
The combustion air intake (through the
120mm-diameter nozzle on the front-
bottom of the appliance, which can be
piped in from outdoors) MUST be fully
independent from the fan air intake
(through the grilles at the bottom of the
sides of the casing, which draw air in from
the room the appliance is fitted in)
because they are separate air circuits.
WARNING: In all cases involving piping
to lead hot air, the piping must be
insulated and tend or slant upwards; never
downwards. Bends, bottlenecks and
horizontal sections more than 1m long
should be avoided as much as possible.
Bear in mind that the air circulating along
the piping loses speed as it advances due
to friction with the walls and the reduction
in temperature. The ends of the piping
used to lead air must be well sealed with
fire sealant or fire cement. We recommend
that the pipes used for forced convection
do not exceed 4 metres in length.
2.3.9. Exterior Frame. Removal and
assembly
If you need to remove the exterior
frame from the appliance (casing,
transportation, etc.), proceed as follows:
•Unscrew the 2 sliding knobs that
control inlets 1 and 2 and remove them.

INSTRUCTIONS FOR THE INSTALLER 13
2.
Figure No.13 - Unscrew the 2 sliding knobs for
inlets 1 and 2
•Unscrew the 6 M6 screws that
secure the sides of the frame.
Figure No.14 - Unscrew the 6 screws that
secure the exterior frame
•Remove the frame from its
housing, being careful not to damage
the enamel. First lift the frame to free
the screws made visible by removing
the sliding knobs and then pull it
forwards.
Figure No.15 - Removing the frame
•Perform the removal process in
reverse order to refit the frame
2.3.10. Fan-potentiometer connection
(only for models C/V)
ITACA c/v models (the models with
fans) are prepared for connection on the
potentiometer supplied. The appliance has
2 hoses protruding from it:
•PROBE hose (TERM), 2 wires.
•Fan hose (VENT), 3 wires.
The two hoses are connected to the
potentiometer according to the connection
diagram in the potentiometer instruction
manual.
The 3-wire power hose for the fan
(LINEA) is not supplied and must be
connected by a person qualified to install
it.
Figure No.16 - Connections to make on the
Itaca fan potentiometer

INSTRUCTIONS FOR THE INSTALLER 14
2.
IMPORTANT: We recommend that a
switch be fitted between the power hose
and the power socket with which to be
able to cut the power supply to the fan
manually and not by means of the
potentiometer switch.
The potentiometer has a safety system
which starts the fan when the thermostat
probe detects temperatures of more than
50ºC even though the potentiometer is set
to OFF; regardless of whether it is in
automatic or manual mode. If the
appliance is no longer going to be loaded
with wood (e.g. when you go to bed) and
the noise of the fan may prove annoying, it
can be switched off by cutting the power
supply to it using the switch suggested
above.
Earth the system on the plastic terminal
strip supplied with the potentiometer.
WARNING: the operating temperature
of the potentiometer supplied by Lacunza
on ITACA C/V models (with fan) is from 0
to 40ºC. Be particularly careful when
choosing the place to fit it so that it
cannot be damaged by temperatures of
over 40ºC. Fully insulate the
potentiometer in order not to encounter
this problem.
Read the potentiometer instruction
manual.
2.4. Chimney flue
The chimney flue must comply with
present standards on the installation of
chimneys.
In rooms equipped with Controlled
Mechanical Ventilation, the ventilation
outlet must never be connected to the
flue.
The appliance must always have its own
chimney flue, never sharing a chimney flue
with another appliance.
2.4.1. Type of flue
The flue must be made of special
material designed to resist the products of
combustion (e.g. stainless steel, enamelled
steel, etc.).
Non-central-heating appliances
(without back boiler) require an insulated,
double-sleeve flue only on those sections
that run outdoors or through cold areas.
Single piping can be used inside the
building, the heat of the gases serving to
heat rooms, insulating only those sections
where excess temperature may cause
damage.
If the chimney is constructed, then it is
necessary to pipe and insulate it to ensure
correct updraught.
The diameter of the pipe must be the
same as the diameter of the flue socket on
the appliance over its entire length in order
to ensure correct operation.
The flue must prevent the entry of
rainwater.
The flue must be clean and airtight over
its entire length.
The flue must be at least 6m tall and the
chimney cap must not hinder the free
release of gases.
If the flue tends to suffer from
downdraught, then it is necessary to fit an
effective anti-downdraught cowl, a static
cowl or a smoke extraction fan, or reshape
the chimney.
Never make 90º bends, due to the great
loss of draught they cause, and reduce 45º
bends down to an absolute minimum. Each
45º bend is equivalent to a 0.5m reduction
in flue length. Horizontal flue sections
should not be installed because they cut
updraught a great deal.
If the flue draws at more than 20 Pa on
12Pa appliances and more than 25Pa on
17Pa appliances, then an effective damper

INSTRUCTIONS FOR THE INSTALLER 15
2.
must be fitted on the flueway. This damper
must be visible and accessible.
The chimney flue must not rest on the
appliance.
Bear in mind that high temperatures
may be reached in the flue, meaning that it
is essential that insulation be enhanced in
sections in which combustible material is
present (wooden beams, furniture, etc.). It
may even be necessary to protect non-
combustible material in order to prevent
breakage, deformation, etc., as a result of
overheating if the material is not designed
to withstand high temperatures.
It must be possible to clean the entire
flue, no sections being left inaccessible for
cleaning purposes.
2.4.2. Chimney crown
The upper end of the chimney must
clear the roof, the roof ridge or any
obstacle located on the roof by at least 1m.
Figure No.17 - Distances between chimney
crown and roof ridge
The chimney crown must clear the
highest point of any neighbouring building
or obstacle located within a 10m radius of
the chimney outlet by more than 1m.

INSTRUCTIONS FOR THE INSTALLER 16
2.
Figure No.18 - Distances between the chimney

INSTRUCTIONS OF USE
The manufacturer accepts no liability
whatsoever for damage caused to parts as
a result of the improper use of non-
recommended fuels, modifications made
to the appliance or how it is installed.
Only use original replacement parts.
All local and national regulations,
including those referring to national and
European standards, must be observed
when using the appliance.
Heat is diffused by radiation and
convection via the front and exterior of the
appliance.
3.1. Fuel
This appliance must not be used as an
incinerator. Do not use non-recommended
fuels.
•Use dry logs (max. 16% humidity),
cut at least 2 years ago, clean of resin
and stored in a sheltered, ventilated
place.
•Use hard woods with high calorie
values and good ember production.
•Large logs should be cut to useable
lengths before being stored. The logs
should have a maximum diameter of
150mm.
•Finely-chopped wood produces
greater heat output, but also burns
more quickly.
Optimum fuels:
•Beech.
Other fuels:
•Oak, chestnut, ash, maple, birch,
elm, etc.
•Pine and eucalyptus logs are low
density and produce very long flames,
and may cause the parts of the
appliance to wear out more quickly
than normal.
•Resinous wood may mean that the
appliance and the flue need to be
cleaned more often.
Non-permitted fuels:
•All types of coal and liquid fuel.
•“Green wood”. Green or damp
wood reduces the performance of the
appliance and leads to soot and tar
build-up on the inner walls of the flue,
obstructing it.
•“Recovered wood”. The burning of
treated woods (railway sleepers,
telegraph posts, plywood, fibreboard,
pallets, etc.) quickly blocks the system
(soot and tar build-up), harms the
environment (pollution, smells) and
may lead to deformation of the firebox
due to overheating.
•All materials which are not wood
(plastic, spray cans, etc.).
Green and reprocessed wood may cause
chimney fires.

humidity of firewood affects its heat
output:

humidity and heat output.

3.3. Lighting
Use of the appliance in warm weather
(warm days, early hours of the afternoon
on sunny days) may lead to lighting and
updraught problems.
Certain weather conditions, such as fog,
ice, humidity entering the flue, etc., may
hinder sufficient updraught in the flue and
lead to suffocation.
Proceed as follows in order to light the
appliance satisfactorily:
•Open the firebox door(s) and open
all the firebox air-intake inlets to the
full.
•Place paper or a firelighter and
some wood chips in the firebox.
•Light the paper or firelighter.
•Leave the door slightly ajar, the
width of two or three fingers, for about
15 minutes until the glass warms up.
•The first time the appliance is lit,
the fire should be gentle to allow the
parts of the appliance to dilate and dry.
Important: The first time it is lit up, the
appliance may give off smoke and strange
smells. This is not a cause for concern.
Open an outdoor window to ventilate the
room during the first few hours of
operation.
If you notice water around the
appliance, this is produced by the
condensation of the moisture in the wood
on lighting the fire. This condensation will
no longer appear when the appliance has
been lit three or four times and has
adapted to its flue. If it does not disappear,
then check the flue draught (length and
diameter of the flue, flue insulation,
airtightness) and the humidity of the wood
used.
3.4. Loading fuel
In order to load firewood, open the
firebox door gently, preventing the sudden
entry of air to the firebox so that smoke
does not enter the room that the appliance
is installed in.
Perform this operation with the glove to
prevent burns to the hands.
The maximum load height is 2 logs with
diameters of approx. 10 cm.
The minimum interval between loads
for nominal heat output is 60 minutes.
Always load with the nominal amount
(see table in section 1.1).
For minimum burning (e.g. at night), use
thicker logs.
When the firebox is loaded, close the
door.
3.5. Operation
The appliance should be operated with
the door closed.
For safety reasons, never close all the
appliance’s combustion-air intakes.
Primary-air intake
By opening this inlet, air enters the
firebox via the firebox grille.
Secondary-air intake
By opening this inlet, air enters the
firebox via the top of the firebox door.
IMPORTANT: Keeping the secondary-air
intake open helps keep the door glass
cleaner for longer.
