1 FEATURES AND TECHNICAL DATA
1.1 FEATURES
1.1.1 Operation
The Supercromo gas-red convector is an independent
heating appliance with sealed combustion chamber and
forced draught.
It has been designed to be installed inside the room to be
heated.
It is suitable for operation with natural gas (G20) and LPG
(G30/G31) (gas-red convector belonging to category
II2H3+ according to EN 1266).
The combustion air intake and the exhaust of ue gases
take place outside via two coaxial pipes and are ensured
by the operation of a blower placed in the combustion cir-
cuit. Therefore, the gas-red convector must be installed
on an external perimetral wall or close to it, depending
on the maximum extension of the pipes (see Paragraph
3.4 p.12 ).
The operation principle of the Supercromo gas-red con-
vector is based on a convective motion of room air that
passes through the gas-red convector from bottom to
top, is heated and diused into the room through the up-
per grille. The recirculation of the room air is facilitated by
the presence of a fan placed in the lower part of the gas-
red convector.
For this reason, do not place clothes, newspa-
pers or any other object that could obstruct the
air outlet directly on the grille. Also make sure
that curtains, backs of chairs or furniture are
not placed at a distance of less than 30 cm from
the gas-red convector.
The operation of the gas-red convector, very simple in
itself, is made completely automatic by the thermostatic
regulation and the programmable timer (standard in the
3002 model, optional in the 3001 model): the user is only
required to switch on the gas-red convector beforehand,
to choose the desired temperature (set on the regulation
thermostat) and, for the 3002 model, the operating period
(set on the programmable timer).
The sealed combustion chamber is the best guarantee of
safety for the environment in which the gas-red convec-
tor is installed: there is no possibility of the products of
combustion leak, nor is the oxygen necessary for combus-
tion taken from the environment. The appliance, once in-
stalled in accordance with the installation standards, does
not require any ventilation openings in the room.
A ame detection device using an ionisation probe in-
terrupts the gas supply in the event of an accidental
shutdown.
1.1.2 Mechanical components
▶ Sealed combustion chamber.
▶ High-eciency tubular steel heat exchanger.
▶ Centrifugal fan.
▶ Ø 49/35 mm coaxial combustion air intake and ue
gas exhaust pipes.
▶ External windproof terminal in aluminium alloy (pat-
ented).
▶ Casing in epoxy powder-coated sheet metal.

If the appliance is installed with separate pipes, suitable
pipes and components, available as optional, must be
used.
At the design stage, it must be veried that the sum of the
pressure drop of all components used does not exceed
the value of the available residual head (Table 3.2 p.13 ).

on the pipe as close as possible to the appliance. To limit
the formation of condensate, it is in any case advisable to
insulate the ue gas pipe with a material resistant to high
temperatures.
Due to the high temperatures that the ue gas pipe
can reach, it is still advisable to insulate it from the
wall and from potential contact with things and
people, for example by using rock wool or glass
wool.
The ue gas exhaust terminal, if used only for ue
gas exhaust, must also be protected against acci-
dental contact with people and things, due to the
high temperatures it can reach.
3.5 INSTALLATION PROCEDURE
In accordance with the installation project, prepare the
gas and electrical supply lines, as well as the holes for the
ue gas outlet and combustion air intake.
3.5.1 Install the gas-red convector on the wall
1. Check the packaging for visible signs of damage, oth-
erwise, notify the carrier immediately.
2. Remove the gas-red convector from its packaging
by rst removing the air intake and ue gas exhaust
pipes. Do not damage or discard the cardboard jig
with the drilling template required for installing the
gas-red convector.
3. Fix the jig to the wall where the gas-red convector is
to be installed, making sure it is perpendicular to the
oor.
4. Drill the hole (Ø 50 mm) to house the larger pipe and
holes A (Figure 3.6 p. 15 ) to x the support brack-
et (drill 6 mm holes to insert the provided wall plugs).
The Ø 50 mm hole for the duct can be made with a
suitable core drill or by means of a succession of small-
er holes made with a simple drill on the perimeter to
be removed.
5. Adjust the length of the pipes (air intake and ue gas
exhaust) to the actual thickness of the wall by cutting
o the excess length: to determine the exact length
see diagram Figure 3.5 p.14 .
The coaxial duct must in any case not be less than
20 cm in length (ue gas pipe 200 + 33 mm, air in-
take pipe 200 + 2 mm).
In the Ø 49 pipe, do not cut the side with the
edging, which will later be used to secure the pipe.
In the Ø 35 pipe, do not cut o the side with a skirt-
ed end that will be used to t the pipe to the gas-
red convector.
6. Remove the jig from the wall.

conditions are in place, rst start-up may be eected.
5.2 CHECKING BURNER GAS PRESSURE
Paragraph reserved exclusively toTACs.
The gas supply circuit is equipped with a gas so-
lenoid valve with double safety shutter and pres-
sure regulator to control the gas ow. All models
are factory-set to operate with natural gas and can
be converted to LPG (see Paragraph 5.3 p. 18 ).
Each gas-red convector is calibrated during fac-
tory testing for operation with natural gas. After
installation, check that the gas pressure at the
burner complies with indications in Paragraph
5.3.1 p.18 .
All adjustments must be made with the appliance
switched on and after removing the casing.
After completion of the gas pressure check at
the burner, the valve adjustment screws must be
sealed.

6.3.1 Switching on
1. Open the gas valve.
2. Power up the gas-red convector.
3. In the presence of the programmable timer (standard
on 3002 model, optional on 3001 model), program the
timer according to your needs (Paragraph 6.4 p.20 ).
Set the manual/programmed button E (Figure
6.1 p. 20 ) to the desired function (button released
or MAN position if you want the appliance to be con-
trolled only by the room thermostat or button pressed
or AUTO position if you want it to be controlled also by
the programmable timer).
For the 3002 model, make sure the programmable
timer operation is set to AUTO if you want to acti-
vate the time schedule.
4. Turn temperature control knob B to the highest tem-
perature setting.
5. After about 30 seconds the gas solenoid valve opens
and the ignition electrode begins to spark, for a maxi-
mum of 10 seconds.
6. If the ame is present, the detection electrode
automatically interrupts the sparking and keeps the
appliance running; the green operation signal light D
lights up.
7. If this is not the case, the control unit locks out the
appliance and the blower stops, lighting up red signal
light C. The reset must be carried out manually using
reset button A.
8. Once the appliance is switched on, turn knob B on the
thermostat clockwise to increase the room tempera-
ture and counterclockwise to decrease it.
9. The fan starts automatically only when it receives
the consent of the ventilation control thermostat, i.e.
when the heat exchanger is hot, in order to prevent
cold air from being introduced into the room and will
switch o when the heat exchanger is cold.
The gradation of the thermostat is purely indicative. The
value of the set temperature depends on the type of room
in which the appliance is installed. A relationship between
the position of the thermostat and the actual room tem-
perature can be obtained by measuring the room temper-
ature at a given thermostat setting.
6.3.2 Switching o
1. To temporarily switch o the appliance (e.g. during
the night period) turn knob B of the thermostat to
the minimum temperature position. This will ensure
a minimum temperature (antifreeze) for the room. For
models with a programmable timer (standard on 3002
model, optional on 3001 model) the appliance can be
temporarily switched o by setting the programmable
timer operation to OFF (Paragraph 6.4 p.20 ).
2. For the season stop it is advisable to disconnect the
appliance from the power supply and close the gas
tap.
In models with a programmable timer (standard on
3002 model, optional on 3001 model), cutting the
power supply loses the day and time setting, which
must be reset the next time the power is turned on.
