IMPORTANT
Before using the space heater, carefully read all of the instructions and follow them scrupulously. The manufacturer cannot be
held responsible for damage to persons and/or property caused by improper use of the equipment.
This instruction manual is an integral part of the equipment and must therefore be stored carefully and passed on with the unit in
the event of a change of ownership.
1. DESCRIPTION
Space heaters described in this manual, are designed for use in
medium to large-sized rooms and buildings where a fixed or mobile
heating system is required.
The air required for combustion is sucked directly by the burner (6)
installed on the heater, and can be supplied:
• from the outside by using the flexible connection tube (available
as an accessory), which avoids consuming oxygen in the room to
be heated, or
• from inside the room to be heated. In this case, the room must be
well ventilated to guarantee sufficient exchange of air.
The flow of hot air is moved by the high-efficiency fan (4): air is
heated by the thermal energy generated during la combustion and
heat from the smoke is transmitted to the fresh air through the
metal walls of the sealed combustion chamber and the heat
exchanger. After the combustion products are cooled, they are
conveyed to a discharge duct and eliminated through a chimney or
flue large enough to guarantee their removal.
The space heaters can work with burners having ON-OFF work
modes and fuelled by natural gas or propane.
Warning
Only burners approved by the manufacturer and listed in
the “TECHNICAL SPECIFICATION TABLE” can be used.
The heater’s certification and warranty will lapse if the
burner is replaced with a non-original model, even if it has
similar specifications.
All of the space heaters are fit with an electronic device that
controls the flame and with:
• safety devices (safety thermostat with manual reset, flame
control, air pressure switch) that trip in case of serious
malfunctions and cause a safety stop. In this case the heater
stops, button (d) lights with a steady red light (Stop Light) and the
heater can resume operation only after the cause of the stop has
been identified and eliminated;
• control devices (temperature controller to control temperature of
air outflow, complete with hour counter, fan thermostat, burner
thermostat, voltage control) that trip in case of minor operating
faults or supply faults, causing temporary stop of the space
heater. In this case, the heater will restart automatically when the
required condition is restored.
The section “TROUBLESHOOTING” describes all possible operating
faults and their possible remedies.
2. CONDITIONS OF SUPPLY

A) Minimum 1 m
B) As short as possible
C) Minimum 1 m
D) Chimney draught H shape
4.7. FIRST START-UP
The heater is supplied after a complete functional test and it’s
therefore prearranged for one of the gas (natural or L.P.G.) indicated
in Tab. I: an adhesive label applied on the manual gas selector valve
(Fig. 4) indicates the working gas (usually it’s natural gas). Should it
necessary to change the kind of gas (from natural gas to L.P.G or
viceversa) follow the detailed instructions indicated in section
“CHANGING TYPE OF GAS”.
Only when the heater has been prearranged according to the proper
working gas it will be possible to carry out the following operations:
• Leak away some gas from the feed pipe;
• Check that the pipe is gas proof;
• Open the gas stopcock and start the hot air generator;
For installation in the U.S.A. at elevation above 2,000 feet (610 m),
the appliance shall be derated 4 per cent for each 1,000 feet (305 m)
of elevation above sea level.
For installation in Canada at elevation above 2,000 feet to 4,500 feet
above sea level, the heater is deratedy reducing the input for the
appropriate fuel in accordance with the rating plate manifold
pressure.
Warning
THE CONVERSION SHALL BE CARRIED OUT BY A
MANUFACTURER’S AUTHORIZED REPRESENTATIVE, IN
ACCORDANCE WITH THE REQUIREMENTS OF THE
MANUFACTURER, PROVINCIAL OR TERRITORIAL
AUTHORITIES HAVING JURISDICTION AND IN
ACCORDANCE WITH THE REQUIREMENTS OF THE
CAN/CGA-B149.1 OR CAN/CGAB149.2 INSTALLATION
CODES.

You can continue and start up the heater only after it has been
prepared it according to the instructions for the work category to be
used.
4.8 CHANGING TYPE OF GAS
This operation may be carried out several times during the working
life of the machine and not only at initial start-up. Therefore, first of
all check the adhesive label attached to the manual gas selector
valve (a) in Fig. (2) to establish the original category of the gas and
then consult Tab. I to identify the supply pressure, the working
pressure, the use conditions of manual valve.
To change kind of gas it is necessary (Fig. 2):
• to remove the sticker on the manual gas selector valve stating the
gas used at that time,
• to remove the screw under the sticker and turn the manual handle
on the correct side according to the condition described in Tab.I and
by following instruction:

EN
L-L 265.00-BM 12 / 24
Fig. 4
• After having moved the handle into the opposite position, put
again the fixing screw and a new sticker on it, stating the gas which
has to be used (a number of different stickers are supplied with the
machine)
Warning
Burner pressure shall not be adjusted: the heater is ready
to run on the new gas
Should it necessary to check the burner pressure:
• connect a manometer to the pressure port located on the burner
support ,
• carry out the pressure reading on the manometer and turn the
pressure regulator (c) if necessary to obtain the correct burner
pressure value indicated in Tab. I
4.9. REGULATING COMBUSTION AND ANALYSING COMBUSTION
PRODUCTS
Warning
The first start-up should always be carried out by a
specialised technician checking the correctness of the
combustion parameters.
Warning
The burner settings are pre-set at the factory and may not
comply with those required, therefore, the settings need to
be checked and, where necessary, corrected.
The adjustment values (gas fuel pressure, burner gas pressure,
combustion head position, air adjustment) for each of the burners
approved for these units are indicated in the “TECHNICAL
SPECIFICATION TABLE”.
The probe used to periodically check combustion and flue smoke
temperatures is to be inserted as indicated:
Combustion is clean and stable when combustion values are as
follows:
NATURAL GAS
G20 - G25
LIQUID GAS
G30 - G31
Index Bacharach - 0 (white)
CO28.5 ÷ 9.5 % 11.5 ÷ 12.5 %
Oxygen (O2) 4.5 ÷ 6 % 4.5 ÷ 6 %
COma 100 ppm 100 ppm
You may have to change the burner settings due to the fuel used
and/or installation conditions (high altitude, air suction pipe with or
without Snorkel, etc.) if combustion parameters are not correct.
When inspection tests are completed, the hole drilled for the probe
must be sealed with a material that is resistant to high
temperatures and that ensures the tube remains airtight.
5. OPERATING INSTRUCTIONS
5.1. START
To start the heater:
• Raise panel (n) on the electrical panel box;
• Make sure the switch (a) is set to “0”;
• Supply electrical power to the space heater by pulling up the
disconnecting switch on the electric power panel: the green lamp
(b) will light up indicating that power is being supplied to the
panel;
•Turn switch (a) to position H or H+V: the burner will begin the start-
up and pre-wash cycle, after which the flame will ignite; after the
combustion chamber has been heating for a few minutes, the
main fan will start up;
Warning
The fan runs continuously in H+V mode, even when the
desired room temperature has been reached, and the
burner turns off.
Warning
In H mode, the fan only runs when the combustion
chamber is sufficiently hot. Therefore, when the desired
room temperature has been reached, the burner turns off
and the fan keeps running only until the combustion
chamber has cooled completely.
• If the heater does not work during the start cycle or work cycle,
consult “TROUBLESHOOTING” to find the cause of the
malfunction.
Warning
If the burner goes into safety stop (lamp m) push reset
button (d) for 3 seconds to restart the heater..
Warning
If the safety thermostat goes into safety stop (lamp h),
push reset button (i) for 3 seconds to restart the heater.
Warning
NEVER do more than two restarts in a row: unburned fuel
can accumulate in the combustion chamber and suddenly
flare up at the next restart.
5.2. STOP
Stop the heater by turning switch (a) to “0” position or, if the heater
is in automatic mode, by setting the room thermostat to a lower
temperature: the burner shuts off and lamp (f) goes out. The fan
keeps working, starting and stopping several times until the
combustion chamber has cooled completely.

EN
L-L 265.00-BM 13 / 24
Warning
Never stop the heater by simply turning off the
disconnecting switch on the panel.
The electrical supply must be disconnected ONLY when
the fan has come to a complete stop.
5.3. VENTILATION
To run the heater only in continuous ventilation mode, turn switch
(a) to the position with the symbol V.
5.4. TEMPERATURE CONTROLLER
The heater is equipped with a temperature controller (g) with LCD
screen, which displays and controls the following parameters:
• Display of air outflow temperature
• Display of hours of operation
• Control of trip temperature of fan thermostat
• Control of trip temperature of burner thermostat
Display of air outflow temperature
The screen displays the measured temperature in [°C]:
Display of hours of operation
Press key (a) twice: the screen shows the operating time in hours
[h]:
Warning
The time shown is not actual heating time, but connection
time to the electrical power supply line.
Reset the counter as follows:
• Turn the heater’s main switch to position “0” (OFF)
• Press button P on the temperature controller for at least 3
seconds: the word “PASS” will flash for 5 seconds
• Enter code “-481” by pressing key (b) several times until obtaining
the number required; press key P to confirm and go to the next
number
• Lastly, press key U: the display again shows the air outflow
temperature
Control of trip temperature of fan thermostat
The temperature controller is programmed to start and stop the
main fan automatically when the combustion chamber reaches the
set temperature. This prevents cold air from blowing when the
burner starts and the combustion chamber is not yet hot enough,
and ensures that residual heat in the heater is dissipated when the
burner stops.
The temperature is factory-set to 35°C, with hysteresis of 5°C.
Red LED “OUT 1” shows the operating state of the fan thermostat:
• LED ON: the fan is on
• LED OFF: the fan is off
Control of trip temperature of burner thermostat
The temperature controller is programmed to start and stop the
burner automatically when the combustion chamber reaches the set
over-temperature. This prevents excessive overheating of the
combustion chamber and subsequent tripping of safety thermostat
L2, which blocks operation of the heater (see chapter 7 for details
on operating problems that cause tripping of safety thermostat L2).
The temperature is factory-set to 95 °C, with hysteresis of 5°C.
Red LED “OUT 2” shows the operating state of the burner
thermostat, while the LED group “- = +” indicates the current
temperature compared to the set temperature:
• if the red arrow at the symbol “-“ is ON, it means that the
temperature is below the set value and, therefore, the thermostat
is ON, i.e., the burner is ON.
• if the green LED at the symbol “=1“ is ON, it means that the
temperature is at the set value.
• if the red arrow at the symbol “+“is ON, it means that the
temperature is above the set value and, therefore, the thermostat
is OFF, i.e., the burner is OFF.
Warning
The trip temperatures of the fan thermostat and burner
thermostat should be changed only if absolutely
necessary. Contact the manufacturer for information
needed to reprogram the temperature controller..
6. MAINTENANCE

6.1. CHECKING THE HEATER AND THE GAS SUPPLY LINE
Perform the following checks:
• Make sure the heater is not installed where there may be a risk of
fire or explosion
• Make sure that flammable materials are kept a safe distance away
• If you smell:
• Open the windows immediately
• Do not touch electrical switches
• Close the gas stopcock
• Find and repair the source of the gas leak
• Do not use the heater if any removed panels have not been
remounted
• Make sure the room to be heated is sufficiently ventilated
• Make sure that the air intake and outlet are completely
unobstructed
• Make sure that the heater is not covered by any sheets or covers;
• Check that the heater is in a fixed and stable position;
• Make sure the heater is constantly monitored during operation and
checked before being started
6.2 CLEANING THE EXTERIOR OF THE HEATER
To ensure efficient operation, clean the following parts:
• Burner:
• Remove all external dirt and debris
• Make sure the air inlet is not obstructed.
• Pipes, connectors and joints:
• Clean with a cloth.
• External body:
• Clean with a cloth.
• Air inlet/outlet:
• Remove all dirt and debris
• Make sure the air inlet is not obstructed.
6.3 Cleaning the motor and the fan
Clean the fan blades and the motor as follows:
• Remove the fan group fixing screws and then remove the fan
group.
• Clean the motor with compressed air.
• Clean the fan blades with a hard brush.
• Reinstall the fan group.
6.4 CHECKING THE ELECTRICAL CONNECTIONS
After detaching the power cable, check all electrical connections as
follows:
• Make sure that all connections are complete and tight.
• If there are traces of dirt or corrosion, clean or replace the
connections if necessary.
• Replace any damaged wires or connectors if necessary.
6.5 CHECKING AND TESTING THE BURNER
To reach the burner:
• Remove the burner fixing screw.
• Remove the burner and follow the checking and cleaning
instructions in the burner manual.
• Reinstall the burner.
• Run the procedures described in paragraphs 4.7 and 4.8 to
measure combustion parameters and check that combustion is
stable and clean.
6.6 CHECKING THE THERMOSTATS
Inspect the thermostats as follows:
• Remove any air outlet connection ducts
• Find the thermostats fixed to the internal panel of the space
heater.
• Clean with a dry cloth, taking care not to cut or bend the capillary
tube.
6.7 CLEANING THE INTERIOR OF THE HEATER
For thorough cleaning, the heater can be cleaned and washed inside
and outside with water. It is however necessary to ensure that:
• the electrical cable is disconnected and unplugged from the
socket
• completely close all access panels
• do not use water jets at a pressure exceeding 70 bar at a distance
less than 30 cm
• completely dry all parts before reconnecting the electrical cable.
6.8 CLEANING THE COMBUSTION CHAMBER
To maintain the burner’s high efficiency and prolong its life, the
procedure described in this paragraph must be done at least once at
the end of the work season or more frequently if there is an
excessive build-up of soot. Excessive soot may be caused by poor
chimney draught, poor fuel quality, poor regulation of the burner, or
more or less frequent alternation of burner starts and stops.
Pay attention during operation: pulsations at start may be due to
excessive amounts of soot.
To access the heat exchanger (1), take off the rear panel (3), remove
the smoke box inspection panel (2), and then remove baffle plates
(7).
To access the combustion chamber (4) remove the burner (5).
Clean with compressed air or, if necessary, with a metal brush to
remove any deposited soot and combustion residues.
Warning
After any technical work, always check that the heater
works correctly.
7. TROUBLESHOOTING
In the event of serious anomalies, various safety devices are able to
block the machine's operation and signal the same:
• on the electrical panel
the blocking signal following intervention by safety
thermostat L2: the reset button is located inside the burner
box.

EN
L-L 265.00-BM 15 / 24
• on the burner
the blocking signal following intervention by the burner's
flame control box.
Warning
NEVER do more than two restarts in a row: unburned fuel
can accumulate in the combustion chamber and suddenly
flare up at the next restart.
If the heater is still not working properly, please contact your
nearest dealer or authorized Service Centre.
