2. IMPORTANT SAFETY INFORMATION
2.1. General Safety Rules
Read instructions carefully. Read and follow all instructions. Place instructions in
a safe place for future reference. Do not allow anyone who has not read these
instructions to assemble, light, adjust or operate the heater.
If the information in this manual is not followed exactly, a fire or explosion may
result causing property damage, personal injury or loss of life.
Service must be performed by a qualified service agency.
Unvented portable heaters use air (oxygen) from the area in which it is used.
Adequate combustion and ventilation air must be provided. Refer to instructions.
Work area safety
•keep work area clean and well lit. Cluttered or dark area invite accidents.
•Do not operate heaters in explosive atmospheres, such as in the presence of
flammable liquids, gas or dust. Heaters create sparks which may ignite the dust
or fumes.
•Keep children and bystanders away while operating a heater. Distractions can
cause you to lose control.
Electrical safety
•heaters plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) heaters. Unmodified plugs and
matching outlets will reduce risk of electric shock.
•Avoid body contract with earthed or grounded surface such as pipes, radiators,
ranges and refrigerators, there is an increased risk of electric shock if your body
is earthed or grounded.
•Do not abuse the cord. Never use the cord for carrying. Pulling or unplugging
the heater. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
•When operating a heater outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
Personal safety
•Stay alert, watch what you are doing and use common sense when operating

4
a heater. Do not use a heater while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating heaters may
result in serious personal injuries.
•Prevent unintentional starting. Ensure the switch is in the off position before
connecting to power source.
•Remove any adjusting key or wrench before turning the heater on. A wrench or
a key left attached to a rotating part of the heater may result in personal injury.
•Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or long hair
can get sucked into the in moving parts of the heater.
Heater use and care
•DO NOT move the heater when it is in operation or when plugged into the
mains supply. Only move heater once it has cooled and it has been unplugged.
•Use the correct heater for your application. The correct heater will do the job
better and safer at the rate for which it was designed.
•Do not use the heater if the switch does not turn in on and off. Any heater that
cannot be controlled with the switch is dangerous and must be repaired.
•Disconnect the plug from the power source before making any adjustments.
Such preventive safety measures reduce the risk of starting the heater
accidentally.
•Store idle heater out of the reach of children and do not allow persons
unfamiliar with the heater or these instructions to operate the power tool. Heaters
are dangerous in the hands of untrained users.
•Maintain heaters. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the heaters operation.
If damaged, have the heater repaired before use. Many accidents are caused by
poorly maintained heaters.
•Use the heater, in accordance with these instructions, taking into account the
working conditions and the work to be performed. Use of the heater for
operations different from those intended could result in a hazardous situation.

4.3 Instructions for Use
4.3.1 Start-up
Fill tank with clean fuel. Only use Diesel or Kerosene.
The fuel gauge on top of the tank allows to check fuel level
Connect the power cord plug to a AC220-240V 50 Hz earthed electrical supply
system.
Earthing is mandatory.
When complete “start-up” above, the left display window shows “--”, the right
display window shows ambient temperature value.
Push the power switch to “ON”(1) position.
The default temperature setting is 20℃, be showed on the left display window.
If the ambient temperature is lower than default temperature, the electrodes start
sparking, after 7 seconds, the heater starts.
If the ambient temperature is higher than default temperature, turn thermostat
control knob to desired temperature, the electrodes start sparking, after 7
seconds, the heater starts.
COLD START-UP: at low temperature keep the air vent hole closed by a finger
during ignition to make start-up easier.
ABNORMAL OPERATION: in case of malfunction (flame failure, reduced air flow,
bad combustion, etc.) the heater stops and the indicator light starts FLASHING
(THE LOCK-OUT MODE code will be showed on the display window).
4.3.2 Manual reset/restart
If the heater is in lock-out mode, check and remove the cause of lock-out before
restarting the heater. To reset, turn the ON/OFF switch to 0 and then again to I. In
case of repeated malfunction, call technical service. Turning the thermostat
control knob will NOT reset the heater.

10
4.3.3 Shut-down
Move switch to "OFF" (O) position. Unplug the unit when not used for a long
time.
Never disconnect the heater from mains to stop it while in operation.
Always allow the cooling sequence to be completed (BGO1601-50), otherwise
the residual heat could damage internal components.
Do not cover the heater. Do not block the air inlet and outlet.
The heater outlet is very hot during operation and after use. Do not touch!
Use personal protecting equipment if needed.
Children should be supervised to ensure that they do not play with the
appliance.
The appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge.
Unplug the heater before moving it. Never pull the cable to unplug or
move the unit.
Do not leave the heater unattended when in use.
Never use the appliance with wet hands or when either the heater or the
power cable is wet.
If the supply cable is damaged, it must be replaced by the manufacturer,
by a service agent or a similar qualified person.
5. CLEANING, MAINTENANCE AND STORAGE
Regularly wipe the enclosure using a soft sponge or cloth. For very dirty parts,
use a sponge wetted with lukewarm water and a mild detergent, then dry using a
clean cloth.
Keep air inlet and fan free from dust and dirt. To clean inner parts, gently blow
compressed air through air inlet.
Regularly inspect the power cable: if worn, cracked or damaged have it replaced
by technical service.
Before storing the heater, make sure it is perfectly cool and dry. Cover the unit
with a plastic bag, put it in its packing box and store it in a dry, ventilated place.
Before starting any maintenance task, shut down, unplug and let the
heater cool down for at least 15 minutes.
Do not attempt any electrical repair yourself. If the heater needs
service or repair, contact a qualified technician.

11
Do not use a faulty unit unless a qualified technician has inspected and
repaired it.
When cleaning, make sure that water does not enter the unit.
Do not open the enclosure to clean the inner parts. Do not spray water
into the heater.
Never use solvents, gasoline, toluene and similar aggressive
chemicals to clean the heater.
The following checks BY QUALIFIED PERSONNEL ONLY are recommended
before every seasonal use:
Nozzle
Carefully unscrew nozzle from nozzle fitting. Blow compressed air through
nozzle orifice to free it from dirt. Replace nozzle if necessary.
Air Filters
Clean air filters. Remove filter end cover (11), wash air intake filter (10) using a
light detergent and dry it thoroughly before re-installing. Replace air delivery filter
(9) once a year.
Ignition Electrodes
Clean, adjust and if necessary replace ignition electrode. For electrode gaps see
Fig. following (dimensions in mm).

12
Compressor Pressure Adjustment
The compressor pressure is factory set and must be checked and
adjusted by qualified technicians only. Tampering with the unit may be
dangerous.
Remove pressure gauge cap. Connect a pressure gauge on the pressure
measuring port on the rear guard. Start heater and read air pressure value. If
necessary adjust pressure to the correct value turning the adjusting screw (the
air vent hole in the adjusting screw middle) clockwise to increase, anticlockwise
to decrease the pressure:
