GENERAL5
Remove the packaging and check that the contents
are present and correct. If any parts are missing, con-
tact your reseller.
The convection heater must be installed by a techni-
cian qualied pursuant to Italian Law 5 March 1990 n°
46, who will issue a declaration of conformity with the
installation regulations and instructions provided by
the manufacturer in the included booklet.
The convection heater must be used for the purpose
specied by the manufacturer.
The manufacturer is not liable in anyway for damage
or injury to persons or animals resulting from incorrect
installation, adjustments or improper use of the appli-
ance.
If the convection heater is not used for a long time, the
following procedure must be completed:
• set the appliance's master switch to OFF;
• set the master switch of the installation (if present) to
OFF or pull its power plug;
• close the gas supply cock.
This booklet is an integral part of the appliance and
must be kept carefully and ALWAYS accompany the
convection heater when it is handed on to another
user or installed in another system.
If it is damaged or lost, please request a new copy
from your local Technical Service.
Certain basic safety rules apply to the use or electrical
and fuel/gas powered equipment, as follows:
Do not allow children or unsupervised disabled per-
sons access to the convection heater.
Do not use electrical equipment such as switches, do-
mestic appliances, etc. if you detect a fuel/gas leak or
combustion fumes in the room.
Should you do so:
• ventilate the room by opening the doors and win-
dows;
• close the fuel/gas supply cock;
• contact Technical Service or a qualied technician

GENERAL WARNINGS
BASIC SAFETY RULES

GENERAL 6
Convection heaters are standalone gas powered room
heaters. They have an atmospheric burner with TYPE C
combustion chamber which is sealed off from the room
to prevent hazardous fumes and gas returning to the
inhabited area.
The combustion air and ue gas are taken from and
discharged outside the room via two concentric pipes,
exploiting the balanced upwards draught of the com-
bustion fumes.
Given their small size, they can be installed even in re-
stricted spaces. They are equipped with a humidier
tank to optimise comfort in the heated room.
They are factory equipped for METHANE operation,
but can be adapted to operation with LPG (G30/G31)
with the included kit of nozzles.
Note: The appliance can be supplied already adap-
ted to LPG operation on request.
SC/SV - The thermostatic ignition/control/regulation
valve, controls all main functions and automatically
shuts off the gas supply in case of malfunction.
The control panel allows you switch on the appliance's
electrical power (appliances with tangential fan or timer
only), to start and stop it manually or automatically us-
ing the timer, to set its heating power and start/stop the
fan, adjust the room temperature setting and restore
operation after a malfunction.
SE - The heat exchanger, which is made of die cast
aluminium and with ns, assures highly efcient com-
bustion. The tangential fan rapidly heats the room when
heating is required.
The appliance is controlled by an electronic controller
which automatically shuts off the gas supply in case of
malfunction.
The control panel allows you switch on the appliance's
electrical power, to start and stop it manually or auto-
matically using the timer, to set its heating power and
start/stop the fan, adjust the room temperature setting
and restore operation after a malfunction.
The convection heater can be identied by:
- its packaging label:
this gives the product name, code, serial number and
gas type.
- nameplate
this gives the serial number, model and main technical
data.
- gas type label:
Gives the appliance's gas type; it must be replaced with
the appropriate new label if the appliance's gas type is
changed.
Spare parts and service can only be provided if the
model of the appliance is properly specified.
Tampering with, removing or losing the nameplate
means that the appliance cannot be properly identi-
fied, and makes it very hard to safely install or ser-
vice the appliance.

15 INSTALLER
GENERAL INFORMATION
The appliance is sealed off from the room; its combustion
air is drawn from outside.
- DO NOT use non-original accessories or parts for the
installation; doing so is hazardous.
- DO NOT route the power cable over hot surfaces such
as the air outlet grilles or ue pipes.
once the appliance has been installed, the installer must
inform the user on how to use it:
- DO NOT place curtains, towels or other such objects
on the appliance; doing so can cause it to malfunction
and compromise the circulation of air in the room.
- DO NOT obstruct the appliance's intake/discharge
terminal with laundry or carpets.
POSITIONING THE APPLIANCE
Before you install the appliance, make sure there is
sufcient clearance for it to operate properly and for
maintenance.
Make sure that the wall to which you are going to mount
it is able to support its weight; check that the included
plugs can bear the appliance's weight in relation to
the material of the wall; if not, use more appropriate
equipment.
Check for wooden, plastic and other non-heat resistant
mouldings which may come into contact with the ue
pipes.
The material of the wall must be able to handle the heat
of the ue pipes (around 180°C)
If the wall is not sufciently heat resistant, you must
provide an air gap around the ue pipe and insulate it
with heat resistant material, or make a hole at least 4 cm
larger than the ue pipe.
Do not install the heater inside the clearances for
bathrooms or showers, or close to water delivery
equipment.
Such installations require special protective equipment
to make the appliance conforming with the applicable
electrical safety regulations.

INTAKE/FLUE PIPE ASSEMBLY AND GAS
CONNECTION
- Cut the pipes to length to suit the thickness of the wall,
as shown in the gure.
IMPORTANT: the outer steel pipe must be cut to the
same length as the thickness of the wall.
IMPORTANT: cut the inner pipe (ue) so that, when it is
installed, it is aligned outwardly with the external pipe
and protrudes by 10 mm from the interior wall. Cut the
pipe using the adhesive cutting tape as a guide stuck to
the pipe at the position of the cut itself.
IMPORTANT: Cutting must be perpendicular to the pipe
axis, please handle with care in order not to deform the
pipes.
Insert the outer pipe through the hole, then t the inner
pipe into the outer one.
- Insert the ue/intake terminal onto the concentric
pipes; mark the centres of the four holes for the 6 mm
wall mounting plugs.
- Remove the terminal, drill the four 6 mm holes, and t
the plugs into them.
- Fit the terminal onto the concentric tube and secure it
tightly to the wall with the wall screws.
IMPORTANT: if the outside pipe protrudes from the
wall (terminal not snug against wall), the burners may
malfunction and even go out or shut off the pilot light,
especially in bad weather (strong wind, rain, etc.).

18INSTALLER
Installing the SPECIAL PIPES KIT from inside the
room
First make the hole in the wall, the cut the SPECIAL
KIT pipes to length (thickness of the wall), removing the
excess length as shown in the gure.
IMPORTANT: The external pipe (xed to the aluminium
outlet) must be cut to match the exact thickness of the
wall.
IMPORTANT: cut the inner pipe (ue) so that, when it is
installed, it is aligned outwardly with the external pipe
and protrudes by 10 mm from the interior wall. Cut the
pipe using the adhesive cutting tape as a guide stuck to
the pipe at the position of the cut itself.
IMPORTANT: Cutting must be perpendicular to the pipe
axis, please handle with care in order not to deform the
pipes.
Before inserting the pipes into the hole in the wall, x
the special kit to the anging on the mounting template.
Use the included screws.
IMPORTANT: The Special Kit is different from the
Standard one: the centring spring is missing. You don’t
need it because the pipes are xed coaxially to the
aluminium outlet.
ASSEMBLING THE CONVECTION HEATER
- Make sure you have completed the previous steps
correctly: You can now install the heater to the wall.
Remove the jacket from its packing. Now extract the
body of the heater.
- Fit the O-Ring gasket to the intake tting.
- Now t the lower section of the gasket to the bottom
of the metal template mounted to the wall. Fit it snugly
so that the discharge stub of the heat exchanger ts
onto the inner pipe in the wall. Tighten the back plate
down with the 2 5MA screws on the bracket (the gasket,
mounted onto the outer tube, must be completely
compressed between the lower chamber of the heater
and the metal template; if it is not, the circuit is no
longer air tight, which is hazardous and can cause
malfunctions).

19 INSTALLER
The equipment is supplied completely cabled and with
a mains plug.
You need only make up a HAR H05 RRF power cable
with at least 1 mm2 cross section wires, assembled to
the loose plug at one end and to the plug or master
switch at the other.
A proper earth connection is obligatory. The
manufacturer is not liable for any damage caused by
unearthed equipment.
For all electrical work, refer to the wiring diagram
included in this booklet
Provide a mains disconnection device upline of the
power cable (omni-polar disconnector or plug), with a
contact air gap of at least 3 mm.
The polarities must be observed: blue is NEUTRAL and
yellow/green is EARTH.
Strip the earth wire at least 2 cm longer than the other
two wires.
Do not use the gas or water pipes to earth the appliance.
Ensure that the heater is congured for your gas supply;
this information is given on the nameplate mounted to
the heat exchanger jacket.
Connect the heater to the gas supply line with the union
and cock included with the appliance, using a rigid pipe
and regulatory ttings.
The tting on the appliance itself is a 3/8” M union per
UNI ISO 7/1.
If the gas supply is on the right side of the heater, use a
nipple to resolve any clearance issues.
Once you have completed the gas line hookup, run the
tightness tests specied in the applicable installation
regulations.
ELECTRICAL HOOKUP
GAS HOOKUP

20INSTALLER
The convection heater is supplied congured for
methane gas (G20), and is pre-adjusted at the factory.
Note: the apparatus can also be requested in the LPG
version.
Before commissioning the heater, check that:
- that the appliance is of the correct gas type;
- that the gas hookup has been completed properly and
the gas cock is open;
- that the electrical hookup has been completed
correctly.
The neutral/phase polarity and the earth connection
must also be correct (for models with fan / timer).
During commissioning, you may note unpleasant odours
and vapours - these are not hazardous. We recommend
ventilating the room thoroughly.
TURN THE APPLIANCE ON:
- Check that the gas cock is open;
- t the loose plug into the socket on the appliance (fan/
timer models);
- Set the master switch, if present, to ON, or t the
power plug into the wall socket (fan/timer models);
- Set the fan mode with the fan On/Off switch (fan
models);
- Set the timer mode switch to Manual (timer models);
SC/SV model (piezoelectric ignition)
- Turn the thermostat knob to 7 (maximum setting).
- Press in and turn the ignition knob from “OFF I”
to “spark” and then “ame”; you will hear a click
(piezoelectric ignition).
- Keep holding the ignition knob down for a few seconds
to allow the ame to stabilise, then release it and check
that the pilot is still on (just as for kitchen hobs).
- With the pilot still burning, turn the ignition knob
leftwards to the “small ame + large ame” position.
